OpenAI, Inc. is an American artificial intelligence (AI) organization headquartered in San Francisco, California. It aims to develop "safe and beneficial" artificial general intelligence (AGI), which it defines as "highly autonomous systems that outperform humans at most economically valuable work".[6] As a leading organization in the ongoing AI boom,[7] OpenAI is known for the GPT family of large language models, the DALL-E series of text-to-image models, and a text-to-video model named Sora.[8][9] Its release of ChatGPT in November 2022 has been credited with catalyzing widespread interest in generative AI.
The organization has a complex corporate structure. As of April 2025, it is led by the non-profit OpenAI, Inc.,[1] founded in 2015 and registered in Delaware, which has multiple for-profit subsidiaries including OpenAI Holdings, LLC and OpenAI Global, LLC.[10] Microsoft invested over $13 billion into OpenAI,[11] and provides Azure cloud computing resources.[12] In October 2025, OpenAI conducted a $6.6 billion share sale that valued the company at $500 billion.[13]
In 2023 and 2024, OpenAI faced multiple lawsuits for alleged copyright infringement against authors and media companies whose work was used to train some of OpenAI's products. In November 2023, OpenAI's board removed Sam Altman as CEO, citing a lack of confidence in him, but reinstated him five days later following a reconstruction of the board. Throughout 2024, roughly half of then-employed AI safety researchers left OpenAI, citing the company's prominent role in an industry-wide problem.[14][15]
Founding
[edit]
In December 2015, OpenAI was founded as a not for profit organization by Sam Altman, Elon Musk, Ilya Sutskever, Greg Brockman, Trevor Blackwell, Vicki Cheung, Andrej Karpathy, Durk Kingma, John Schulman, Pamela Vagata, and Wojciech Zaremba, with Sam Altman and Elon Musk as the co-chairs.[16][17] A total of $1 billion in capital was pledged by Sam Altman, Greg Brockman, Elon Musk, Reid Hoffman, Jessica Livingston, Peter Thiel, Amazon Web Services (AWS), and Infosys.[18][19] The actual collected total amount of contributions was only $130 million until 2019.[10]
The organization stated it would "freely collaborate" with other institutions and researchers by making some of its patents and research open to the public.[20][21][16] OpenAI was initially run from Brockman's living room.[22] It was later headquartered at the Pioneer Building in the Mission District, San Francisco.[23][24]
According to OpenAI's charter, its founding mission is "to ensure that artificial general intelligence (AGI)—by which we mean highly autonomous systems that outperform humans at most economically valuable work—benefits all of humanity."[6]
Musk and Altman stated in 2015 that they were partly motivated by concerns about AI safety and existential risk from artificial general intelligence.[25][26] OpenAI stated that "it's hard to fathom how much human-level AI could benefit society", and that it is equally difficult to comprehend "how much it could damage society if built or used incorrectly".[21] The startup also wrote that AI "should be an extension of individual human wills and, in the spirit of liberty, as broadly and evenly distributed as possible",[21] and that "because of AI's surprising history, it's hard to predict when human-level AI might come within reach. When it does, it'll be important to have a leading research institution which can prioritize a good outcome for all over its own self-interest."[27] Co-chair Sam Altman expected a decades-long project that eventually surpasses human intelligence.[28]
Brockman met with Yoshua Bengio, one of the "founding fathers" of deep learning, and drew up a list great AI researchers.[16] Brockman was able to hire nine of them as the first employees in December 2015.[16] OpenAI did not pay AI researchers salaries comparable to those of Facebook or Google.[16] It also did not pay stock options which AI researchers typically get. Nevertheless, OpenAI spent $7 million on its first 52 employees in 2016.[29] OpenAI's potential and mission drew these researchers to the firm; a Google employee said he was willing to leave Google for OpenAI "partly because of the very strong group of people and, to a very large extent, because of its mission."[16] OpenAI co-founder Wojciech Zaremba stated that he turned down "borderline crazy" offers of two to three times his market value to join OpenAI instead.[16]
In April 2016, OpenAI released a public beta of "OpenAI Gym", its platform for reinforcement learning research.[30] Nvidia gifted its first DGX-1 supercomputer to OpenAI in August 2016 to help it train larger and more complex AI models with the capability of reducing processing time from six days to two hours.[31][32] In December 2016, OpenAI released "Universe", a software platform for measuring and training an AI's general intelligence across the world's supply of games, websites, and other applications.[33][34][35][36]
Corporate structure
[edit]
Transition from non-profit
[edit]In 2019, OpenAI transitioned from non-profit to "capped" for-profit, with the profit being capped at 100 times any investment.[37] According to OpenAI, the capped-profit model allows OpenAI Global, LLC to legally attract investment from venture funds and, in addition, to grant employees stakes in the company.[38] Many top researchers work for Google Brain, DeepMind, or Facebook, which offer stock options that a nonprofit would be unable to.[39] Before the transition, public disclosure of the compensation of top employees at OpenAI was legally required.[40]
The company then distributed equity to its employees and partnered with Microsoft,[41] announcing an investment package of $1 billion into the company. Since then, OpenAI systems have run on an Azure-based supercomputing platform from Microsoft.[42][43][44]
OpenAI Global, LLC then announced its intention to commercially license its technologies.[45] It planned to spend $1 billion "within five years, and possibly much faster".[46] Altman stated that even a billion dollars may turn out to be insufficient, and that the lab may ultimately need "more capital than any non-profit has ever raised" to achieve artificial general intelligence.[47]
The nonprofit, OpenAI, Inc., is the sole controlling shareholder of OpenAI Global, LLC, which, despite being a for-profit company, retains a formal fiduciary responsibility to OpenAI, Inc.'s nonprofit charter. A majority of OpenAI, Inc.'s board is barred from having financial stakes in OpenAI Global, LLC.[38] In addition, minority members with a stake in OpenAI Global, LLC are barred from certain votes due to conflict of interest.[39] Some researchers have argued that OpenAI Global, LLC's switch to for-profit status is inconsistent with OpenAI's claims to be "democratizing" AI.[48]
On February 29, Elon Musk filed a lawsuit against OpenAI and CEO Sam Altman, accusing them of shifting focus from public benefit to profit maximization—a case OpenAI dismissed as "incoherent" and "frivolous," though Musk later revived legal action against Altman and others in August.[49][50][51][52]
On April 9, OpenAI countersued Musk in federal court, alleging that he had engaged in "bad-faith tactics" to slow the company's progress and seize its innovations for his personal benefit. OpenAI also argued that Musk had previously supported the creation of a for-profit structure and had expressed interest in controlling OpenAI himself. The countersuit seeks damages and legal measures to prevent further alleged interference.[53]
On February 10, 2025, a consortium of investors led by Elon Musk submitted a $97.4 billion unsolicited bid to buy the nonprofit that controls OpenAI, declaring willingness to match or exceed any better offer.[54][55] The offer was rejected on 14 February 2025, with OpenAI stating that it was not for sale,[56] but the offer complicated Altman's restructuring plan by suggesting a lower bar for how much the nonprofit should be valued.[55]
OpenAI, Inc. was originally designed as a nonprofit in order to ensure that AGI "benefits all of humanity" rather than "the private gain of any person". In 2019, it created OpenAI Global, LLC, a capped-profit subsidiary controlled by the nonprofit. In December 2024, OpenAI proposed a restructuring plan to convert the capped-profit into a Delaware-based public benefit corporation (PBC), and to release it from the control of the nonprofit. The nonprofit would sell its control and other assets, getting equity in return, and would use it to fund and pursue separate charitable projects, including in science and education. OpenAI's leadership described the change as necessary to secure additional investments, and claimed that the nonprofit's founding mission to ensure AGI "benefits all of humanity" would be better fulfilled.[57]
The plan has been criticized by former employees. A legal letter named "Not For Private Gain" asked the attorneys general of California and Delaware to intervene, stating that the restructuring is illegal and would remove governance safeguards from the nonprofit and the attorneys general.[58] The letter argues that OpenAI's complex structure was deliberately designed to remain accountable to its mission, without the conflicting pressure of maximizing profits. It contends that the nonprofit is best positioned to advance its mission of ensuring AGI benefits all of humanity by continuing to control OpenAI Global, LLC, whatever the amount of equity that it could get in exchange.[59] PBCs can choose how they balance their mission with profit-making. Controlling shareholders have a large influence on how closely a PBC sticks to its mission.[60][59]
According to UCLA Law staff, to change its purpose, OpenAI would have to prove that its current purposes have become unlawful, impossible, impracticable, or wasteful.[61]
In May 2025, the nonprofit renounced plans to cede control of OpenAI after outside pressure. However, the capped-profit still plans to transition to a public benefit corporation,[62] which critics said would diminish the nonprofit's control.[63]
Partnership with Microsoft
[edit]In January 2023, OpenAI Global, LLC was in talks for funding that would value the company at $29 billion, double its 2021 value.[64] On January 23, 2023, Microsoft announced a new US$10 billion investment in OpenAI Global, LLC over multiple years, partially needed to use Microsoft's cloud-computing service Azure.[65][66]
On September 21, 2023, Microsoft had begun rebranding all variants of its Copilot to Microsoft Copilot, including the former Bing Chat and the Microsoft 365 Copilot.[67] This strategy was followed in December 2023 by adding the MS-Copilot to many installations of Windows 11 and Windows 10 as well as a standalone Microsoft Copilot app released for Android[68] and one released for iOS thereafter.[69]
Finances
[edit]This section appears to be slanted towards recent events. (August 2025) |
In 2017, OpenAI spent $7.9 million, a quarter of its functional expenses, on cloud computing alone.[70] In comparison, DeepMind's total expenses in 2017 were $442 million. In the summer of 2018, training OpenAI's Dota 2 bots required renting 128,000 CPUs and 256 GPUs from Google for multiple weeks.[38]
In October 2024, OpenAI completed a $6.6 billion capital raise with a $157 billion valuation including investments from Microsoft, Nvidia, and SoftBank.[71]
On January 21, 2025, Donald Trump announced The Stargate Project, a joint venture between OpenAI, Oracle, SoftBank and MGX to build an AI infrastructure system in conjunction with the US government. The project takes its name from OpenAI's existing "Stargate" supercomputer project and is estimated to cost $500 billion. The partners plan to fund the project over the next four years.[72] In July, the United States Department of Defense announced that OpenAI had received a $200 million contract for AI in the military, along with Anthropic, Google, and xAI.[73] In the same month, the company made a deal with the UK Government to use ChatGPT and other AI tools in public services.[74][75] OpenAI subsequently began a $50 million fund to support nonprofit and community organizations.[76]
In April 2025, OpenAI raised $40 billion at a $300 billion post-money valuation, which was the highest-value private technology deal in history. The financing round was led by SoftBank, with other participants including Microsoft, Coatue, Altimeter and Thrive.[77][78]
In July 2025, the company reported annualized revenue of $12 billion.[79][80] This was an increase from $3.7 billion in 2024, which was driven by ChatGPT subscriptions, which reached 20 million paid subscribers by April 2025, up from 15.5 million at the end of 2024, alongside a rapidly expanding enterprise customer base that grew to five million business users.[81][82][83]
The company cash burn remains high due to the intensive computational costs required to train and run large language models. It projects to lose $8 billion in 2025.[84][85]
Looking ahead, OpenAI has revised upward its long-term spending projections, now expecting to burn approximately $115 billion through 2029—roughly $80 billion more than the company's previous estimates.[86] The annual cash burn is projected to escalate significantly, with spending expected to reach $17 billion in 2026, $35 billion in 2027, and $45 billion in 2028.[87][88] These expenditures are primarily allocated toward expanding compute infrastructure, developing proprietary AI chips, constructing data centers, and funding intensive model training programs, with more than half of the spending through the end of the decade expected to support research-intensive compute for model training and development.[89]
The company's financial strategy reflects a strategy of prioritizing market expansion and technological advancement over near-term profitability, with OpenAI targeting cash flow positive operations by 2029 and projecting revenue of approximately $200 billion by 2030.[87] This aggressive spending trajectory underscores both the enormous capital requirements of scaling cutting-edge AI technology and OpenAI's commitment to maintaining its position as a leader in the artificial intelligence industry.[90]
In October 2025, OpenAI completed an employee share sale of up to $10 billion to existing investors which valued the company at $500 billion. The deal values OpenAI as the most valuable privately owned company in the world—surpassing SpaceX as the world's most valuable private company.[91]
Firing of Altman
[edit]
On November 17, 2023, Sam Altman was removed as CEO when its board of directors (composed of Helen Toner, Ilya Sutskever, Adam D'Angelo and Tasha McCauley) cited a lack of confidence in him. Chief Technology Officer Mira Murati took over as interim CEO. Greg Brockman, the president of OpenAI, was also removed as chairman of the board[92][93] and resigned from the company's presidency shortly thereafter.[94] Three senior OpenAI researchers subsequently resigned: director of research and GPT-4 lead Jakub Pachocki, head of AI risk Aleksander Mądry, and researcher Szymon Sidor.[95][96]
On November 18, 2023, there were reportedly talks of Altman returning as CEO amid pressure placed upon the board by investors such as Microsoft and Thrive Capital, who objected to Altman's departure.[97] Although Altman himself spoke in favor of returning to OpenAI, he has since stated that he considered starting a new company and bringing former OpenAI employees with him if talks to reinstate him didn't work out.[98] The board members agreed "in principle" to resign if Altman returned.[99] On November 19, 2023, negotiations with Altman to return failed and Murati was replaced by Emmett Shear as interim CEO.[100] The board initially contacted Anthropic CEO Dario Amodei (a former OpenAI executive) about replacing Altman, and proposed a merger of the two companies, but both offers were declined.[101]
On November 20, 2023, Microsoft CEO Satya Nadella announced Altman and Brockman would be joining Microsoft to lead a new advanced AI research team, but added that they were still committed to OpenAI despite recent events.[102] Before the partnership with Microsoft was finalized, Altman gave the board another opportunity to negotiate with him.[103] About 738 of OpenAI's 770 employees, including Murati and Sutskever, signed an open letter stating they would quit their jobs and join Microsoft if the board did not rehire Altman and then resign.[104][105] This prompted OpenAI investors to consider legal action against the board as well.[106] In response, OpenAI management sent an internal memo to employees stating that negotiations with Altman and the board had resumed and would take some time.[107]
On November 21, 2023, after continued negotiations, Altman and Brockman returned to the company in their prior roles along with a reconstructed board made up of new members Bret Taylor (as chairman) and Lawrence Summers, with D'Angelo remaining.[108][109] Concerns about Altman's response to this development, specifically regarding the discovery's potential safety implications, were reportedly raised with the company's board shortly before Altman's firing.[110] On November 29, 2023, OpenAI announced that an anonymous Microsoft employee had joined the board as a non-voting member to observe the company's operations;[111] Microsoft resigned from the board in July 2024.[112]
In February 2024, the Securities and Exchange Commission subpoenaed OpenAI's internal communication to determine if Altman's alleged lack of candor misled investors.[113]
In 2024, following the temporary removal of Sam Altman and his return, many employees gradually left OpenAI, including most of the original leadership team and a significant number of AI safety researchers.[114][115]
Acquisitions
[edit]In August 2023, it was announced that OpenAI had acquired the New York-based start-up Global Illumination, a company that deploys AI to develop digital infrastructure and creative tools.[116]
In June 2024, OpenAI acquired Multi, a startup focused on remote collaboration.[117]
In March 2025, OpenAI reached a deal with CoreWeave to acquire $350 million worth of CoreWeave shares and access to AI infrastructure, in return for $11.9 billion paid over five years. Microsoft was already CoreWeave's biggest customer in 2024.[118] Alongside their other business dealings, OpenAI and Microsoft were renegotiating the terms of their partnership to facilitate a potential future initial public offering by OpenAI, while ensuring Microsoft's continued access to advanced AI models.[119]
On May 21, OpenAI announced the $6.5 billion acquisition of io, an AI hardware start-up founded by former Apple designer Jony Ive in 2024.[120][121][122]
In September 2025, OpenAI agreed to acquire the product testing startup Statsig for $1.1 billion in an all-stock deal and appointed Statsig's founding CEO Vijaye Raji as OpenAI's chief technology officer of applications.[123] The company also announced development of an AI-driven hiring service designed to rival LinkedIn.[124]
OpenAI acquired personal finance app Roi in October 2025.[125]
Corporate partnerships
[edit]OpenAI has been criticized for outsourcing the annotation of data sets to Sama, a company based in San Francisco that employed workers in Kenya. These annotations were used to train an AI model to detect toxicity, which could then be used to moderate toxic content, notably from ChatGPT's training data and outputs. However, these pieces of text usually contained detailed descriptions of various types of violence, including sexual violence. The investigation uncovered that OpenAI began sending snippets of data to Sama as early as November 2021. The four Sama employees interviewed by Time described themselves as mentally scarred. OpenAI paid Sama $12.50 per hour of work, and Sama was redistributing the equivalent of between $1.32 and $2.00 per hour post-tax to its annotators. Sama's spokesperson said that the $12.50 was also covering other implicit costs, among which were infrastructure expenses, quality assurance and management.[126]
OpenAI began collaborating with Broadcom in 2024 to design a custom AI chip capable of both training and inference targeted for mass production in 2026 and to be manufactured by TSMC in 3 nm node. This initiative intended to reduce OpenAI's dependence on Nvidia GPUs, which are costly and face high demand in the market.[127][128][129]
In January 2024, Arizona State University purchased ChatGPT Enterprise in OpenAI's first deal with a university.[130]
In June, Apple Inc. signed a contract with OpenAI to integrate ChatGPT features into its products as part of its new Apple Intelligence initiative.[131][132]
In June, OpenAI began renting Google Cloud's Tensor Processing Units (TPUs) to support ChatGPT and related services, marking its first meaningful use of non‑Nvidia AI chips.[133]
In September 2025, it was revealed that OpenAI signed a contract with Oracle to purchase $300 billion in computing power over the next five years.[134]
In September 2025, OpenAI and NVIDIA announced a partnership that included a potential deployment of at least 10 gigawatts of NVIDIA systems and a $100 billion investment from NVIDIA in OpenAI.[135]
In October 2025, OpenAI announced a multi-billion dollar deal with AMD.[136] OpenAI committed to purchasing six gigawatts worth of AMD chips, starting with the MI450. OpenAI will have the option to buy up to 160 million shares of AMD, about 10% of the company, depending on development, performance and share price targets.[137]
Government contracting
[edit]OpenAI provides LLMs to the Artificial Intelligence Cyber Challenge, and to the Advanced Research Projects Agency for Health.[138] In October 2024, The Intercept revealed that OpenAI's tools are considered "essential" for AFRICOM's mission and included in an "Exception to Fair Opportunity" contractual agreement between the United States Department of Defense and Microsoft.[139] In December 2024, OpenAI said it would partner with defense-tech company Anduril to build drone defense technologies for the United States and its allies.[140]
In 2025, OpenAI's Chief Product Officer, Kevin Weil, was commissioned lieutenant colonel in the U.S. Army to join Detachment 201 as senior advisor.[141]
In June 2025, the U.S. Department of Defense awarded OpenAI a $200 million one-year contract to develop AI tools for military and national security applications. OpenAI announced a new program, OpenAI for Government, to give federal, state, and local governments access to its models, including ChatGPT.[142][143]

Development
[edit]In February 2019, GPT-2 was announced, which gained attention for its ability to generate human-like text.[144]
In 2020, OpenAI announced GPT-3, a language model trained on large internet datasets. GPT-3 is aimed at natural language answering questions, but it can also translate between languages and coherently generate improvised text. It also announced that an associated API, named the API, would form the heart of its first commercial product.[145]
Eleven employees left OpenAI, mostly between December 2020 and January 2021, in order to establish Anthropic.[146]
In 2021, OpenAI introduced DALL-E, a specialized deep learning model adept at generating complex digital images from textual descriptions, utilizing a variant of the GPT-3 architecture.[147]

In December 2022, OpenAI received widespread media coverage after launching a free preview of ChatGPT, its new AI chatbot based on GPT-3.5. According to OpenAI, the preview received over a million signups within the first five days.[149] According to anonymous sources cited by Reuters in December 2022, OpenAI Global, LLC was projecting $200 million of revenue in 2023 and $1 billion in revenue in 2024.[150]
Google announced a similar AI application (Bard), after ChatGPT was launched, fearing that ChatGPT could threaten Google's place as a go-to source for information.[151][152]
On February 7, 2023, Microsoft announced that it was building AI technology based on the same foundation as ChatGPT into Microsoft Bing, Edge, Microsoft 365 and other products.[153]
On March 14, 2023, OpenAI released GPT-4, both as an API (with a waitlist) and as a feature of ChatGPT Plus.[154]
On November 6, 2023, OpenAI launched GPTs, allowing individuals to create customized versions of ChatGPT for specific purposes, further expanding the possibilities of AI applications across various industries.[155] On November 14, 2023, OpenAI announced they temporarily suspended new sign-ups for ChatGPT Plus due to high demand.[156] Access for newer subscribers re-opened a month later on December 13.[157]
In December 2024, the company launched the Sora model.[158][159] It also launched OpenAI o1, an early reasoning model that was internally codenamed strawberry.[160] Additionally, ChatGPT Pro—a $200/month subscription service offering unlimited o1 access and enhanced voice features—was introduced, and preliminary benchmark results for the upcoming OpenAI o3 models were shared.[161]
On January 23, 2025, OpenAI released Operator, an AI agent and web automation tool for accessing websites to execute goals defined by users. The feature was only available to Pro users in the United States.[162][163] OpenAI released deep research agent, nine days later. It scored a 27% accuracy on the benchmark Humanity's Last Exam (HLE).[164] Altman later stated GPT-4.5 would be the last model without full chain-of-thought reasoning.[165][166]
In July 2025, reports indicated that AI models by both OpenAI and Google DeepMind solved mathematics problems at the level of top-performing students in the International Mathematical Olympiad. OpenAI's large language model was able to achieve gold medal-level performance, reflecting significant progress in AI's reasoning abilities.[167]
In September 2025, OpenAI released a first-of-its-kind study revealing how people use ChatGPT for everyday tasks.[168][169] The study found that "non-work tasks" (according to an LLM-based classifier) account for more than 72 percent of all ChatGPT usage, with a minority of overall usage related to business productivity.[170]
On October 6, OpenAI unveiled its Agent Builder platform during the company's DevDay event. The platform features a drag-and-drop visual interface that allows developers and businesses to design, test, and deploy agentic workflows without requiring extensive coding expertise.[171]
On October 21 2025, OpenAI introduced ChatGPT Atlas, a browser integrating the ChatGPT assistant directly into web navigation, to compete with existing browsers such as Google Chrome and Apple Safari.[172][173][174]
Transparency
[edit]In March 2023, the company was criticized for disclosing particularly few technical details about products like GPT-4, contradicting its initial commitment to openness and making it harder for independent researchers to replicate its work and develop safeguards. OpenAI cited competitiveness and safety concerns to justify this strategic turn. OpenAI's former chief scientist Ilya Sutskever argued in 2023 that open-sourcing increasingly capable models was increasingly risky, and that the safety reasons for not open-sourcing the most potent AI models would become "obvious" in a few years.[175]
Alignment
[edit]In July 2023, OpenAI launched the superalignment project, aiming to find within 4 years how to align future superintelligences by automating alignment research using AI.[176] OpenAI promised to dedicate 20% of its computing resources to the project, although the team denied receiving anything close to 20%.[177] OpenAI ended the project in May 2024 after its co-leaders Ilya Sutskever and Jan Leike left the company.[178]
Leaked conversations
[edit]In August 2025, OpenAI was criticized after thousands of private ChatGPT conversations were inadvertently exposed to public search engines like Google due to an experimental "share with search engines" feature. The opt-in toggle, intended to allow users to make specific chats discoverable, resulted in some discussions including personal details such as names, locations, and intimate topics appearing in search results when users accidentally enabled it while sharing links. OpenAI announced the feature's permanent removal on August 1, 2025, and the company began coordinating with search providers to remove the exposed content, emphasizing that it was not a security breach but a design flaw that heightened privacy risks. CEO Sam Altman acknowledged the issue in a podcast, noting users often treat ChatGPT as a confidant for deeply personal matters, which amplified concerns about AI handling sensitive data.[179][180][181]

On March 3, 2023, Reid Hoffman resigned from his board seat, citing a desire to avoid conflicts of interest with his investments in AI companies via Greylock Partners, and his co-founding of the AI startup Inflection AI. Hoffman remained on the board of Microsoft, a major investor in OpenAI.[196]
In May 2024, Chief Scientist Ilya Sutskever resigned and was succeeded by Jakub Pachocki. Co-leader Jan Leike also departed amid concerns over safety and trust.[183][197] OpenAI then signed deals with Reddit, News Corp, Axios, and Vox Media.[198][199] Paul Nakasone then joined the board of OpenAI.[200]
In August 2024, cofounder John Schulman left OpenAI to join Anthropic, and OpenAI's president Greg Brockman took extended leave until November.[201][202]
In September 2024, CTO Mira Murati left the company.[203][204]
Governance and legal issues
[edit]
In May 2023, Sam Altman, Greg Brockman and Ilya Sutskever posted recommendations for the governance of superintelligence.[205] They stated that superintelligence could happen within the next 10 years, allowing a "dramatically more prosperous future" and that "given the possibility of existential risk, we can't just be reactive". They proposed creating an international watchdog organization similar to IAEA to oversee AI systems above a certain capability threshold, suggesting that relatively weak AI systems on the other side should not be overly regulated. They also called for more technical safety research for superintelligences, and asked for more coordination, for example through governments launching a joint project which "many current efforts become part of".[205][206]
In July 2023, the FTC issued a civil investigative demand to OpenAI to investigate whether the company's data security and privacy practices to develop ChatGPT were unfair or harmed consumers (including by reputational harm) in violation of Section 5 of the Federal Trade Commission Act of 1914.[207][208][209] These are typically preliminary investigative matters and are nonpublic, but the FTC's document was leaked.[210][209] In July 2023, the FTC launched an investigation into OpenAI over allegations that the company scraped public data and published false and defamatory information. They asked OpenAI for comprehensive information about its technology and privacy safeguards, as well as any steps taken to prevent the recurrence of situations in which its chatbot generated false and derogatory content about people.[211] The agency then reported concern with circular spending in which, for example, Microsoft gives OpenAI credit to Microsoft Azure and the companies provide each other access to engineering talent was of particular concern for its potential negative impacts to the public.[212]
In September 2024, OpenAI's global affairs chief endorsed the UK's "smart" AI regulation during testimony to a House of Lords committee.[213]
In February 2025, OpenAI CEO Sam Altman stated that the company is interested in collaborating with the People's Republic of China, despite regulatory restrictions imposed by the U.S. government.[214] This shift comes in response to the growing influence of the Chinese artificial intelligence company DeepSeek, which has disrupted the AI market with open models, including DeepSeek V3 and DeepSeek R1.[215][216] In response to DeepSeek, OpenAI overhauled its security operations to better guard against industrial espionage, particularly amid allegations that DeepSeek had improperly copied OpenAI's distillation techniques.[217]
According to Oliver Roberts, in March 2025, the United States had 781 state AI bills or laws. OpenAI advocated for preempting state AI laws with federal laws.[218] According to Scott Kohler, OpenAI has opposed California's AI legislation and suggested that the state bill encroaches on a more competent federal government.[219] Public Citizen opposed a federal preemption on AI and pointed to OpenAI's growth and valuation as evidence that existing state laws have not hampered innovation.[220]
Non-disparagement agreements
[edit]Before May 2025, OpenAI required departing employees to sign a lifelong non-disparagement agreement forbidding them from criticizing OpenAI and acknowledging the existence of the agreement. Daniel Kokotajlo, a former employee, publicly stated that he forfeited his vested equity in OpenAI in order to leave without signing the agreement.[221][222] Sam Altman stated that he was unaware of the equity cancellation provision, and that OpenAI never enforced it to cancel any employee's vested equity.[223] However, leaked documents and emails refute this claim.[224] On May 23, 2024, OpenAI sent a memo releasing former employees from the agreement.[225]
Copyright
[edit]OpenAI was sued for copyright infringement by authors Sarah Silverman, Matthew Butterick, Paul Tremblay and Mona Awad in July 2023.[226][227][228] In September 2023, 17 authors, including George R. R. Martin, John Grisham, Jodi Picoult and Jonathan Franzen, joined the Authors Guild in filing a class action lawsuit against OpenAI, alleging that the company's technology was illegally using their copyrighted work.[229][230] The New York Times also sued the company in late December 2023.[227][231] In May 2024 it was revealed that OpenAI had destroyed its Books1 and Books2 training datasets, which were used in the training of GPT-3, and which the Authors Guild believed to have contained over 100,000 copyrighted books.[232]
In 2021, OpenAI developed a speech recognition tool called Whisper. OpenAI used it to transcribe more than one million hours of YouTube videos into text for training GPT-4. The automated transcription of YouTube videos raised concerns within OpenAI employees regarding potential violations of YouTube's terms of service, which prohibit the use of videos for applications independent of the platform, as well as any type of automated access to its videos. Despite these concerns, the project proceeded with notable involvement from OpenAI's president, Greg Brockman. The resulting dataset proved instrumental in training GPT-4.[233]
In February 2024, The Intercept as well as Raw Story and Alternate Media Inc. filed lawsuit against OpenAI on copyright litigation ground.[234][235] The lawsuit is said to have charted a new legal strategy for digital-only publishers to sue OpenAI.[236]
On April 30, 2024, eight newspapers filed a lawsuit in the Southern District of New York against OpenAI and Microsoft, claiming illegal harvesting of their copyrighted articles. The suing publications included The Mercury News, The Denver Post, The Orange County Register, St. Paul Pioneer Press, Chicago Tribune, Orlando Sentinel, Sun Sentinel, and New York Daily News.[237]
In June 2023, a lawsuit claimed that OpenAI scraped 300 billion words online without consent and without registering as a data broker. It was filed in San Francisco, California, by sixteen anonymous plaintiffs.[238] They also claimed that OpenAI and its partner as well as customer Microsoft continued to unlawfully collect and use personal data from millions of consumers worldwide to train artificial intelligence models.[239]
On May 22, 2024, OpenAI entered into an agreement with News Corp to integrate news content from The Wall Street Journal, the New York Post, The Times, and The Sunday Times into its AI platform. Meanwhile, other publications like The New York Times chose to sue OpenAI and Microsoft for copyright infringement over the use of their content to train AI models.[240] In November 2024, a coalition of Canadian news outlets, including the Toronto Star, Metroland Media, Postmedia, The Globe and Mail, The Canadian Press and CBC, sued OpenAI for using their news articles to train its software without permission.[241]
In October 2024 during a New York Times interview, Suchir Balaji accused OpenAI of violating copyright law in developing its commercial LLMs which he had helped engineer. He was a likely witness in a major copyright trial against the AI company, and was one of several of its current or former employees named in court filings as potentially having documents relevant to the case. On November 26, 2024, Balaji shot himself dead. His death led to conspiracy theories suggesting he had been deliberately silenced.[242][243] California Congressman Ro Khanna endorsed calls for an investigation.[244][245]
GDPR compliance
[edit]In April 2023, the EU's European Data Protection Board (EDPB) formed a dedicated task force on ChatGPT "to foster cooperation and to exchange information on possible enforcement actions conducted by data protection authorities" based on the "enforcement action undertaken by the Italian data protection authority against OpenAI about the ChatGPT service".[246]
In late April 2024 NOYB filed a complaint with the Austrian Datenschutzbehörde against OpenAI for violating the European General Data Protection Regulation. A text created with ChatGPT gave a false date of birth for a living person without giving the individual the option to see the personal data used in the process. A request to correct the mistake was denied. Additionally, neither the recipients of ChatGPT's work nor the sources used, could be made available, OpenAI claimed.[247]
Military and warfare
[edit]OpenAI was criticized for lifting its ban on using ChatGPT for "military and warfare". Up until January 10, 2024, its "usage policies" included a ban on "activity that has high risk of physical harm, including", specifically, "weapons development" and "military and warfare". Its new policies prohibit "[using] our service to harm yourself or others" and to "develop or use weapons".[248][249]
Wrongful-death lawsuit over ChatGPT safety (2025)
[edit]In August 2025, the parents of a 16-year-old boy who died by suicide filed a wrongful death lawsuit against OpenAI (and CEO Sam Altman), alleging that months of conversations with ChatGPT about mental health and methods of self-harm contributed to their son's death and that safeguards were inadequate for minors. OpenAI expressed condolences and said it was strengthening protections (including updated crisis response behavior and parental controls). Coverage described it as a first-of-its-kind wrongful death case targeting the company's chatbot. The complaint was filed in California state court in San Francisco.[250]

Founding and Initial Motivations (2015)
OpenAI was founded on December 11, 2015, as a non-profit organization focused on artificial intelligence research.[2] Key founders included Sam Altman of Y Combinator, Elon Musk of SpaceX and Tesla, Greg Brockman as CTO, Ilya Sutskever as research director (recruited from Google), and others such as Wojciech Zaremba, John Schulman, Trevor Blackwell, Vicki Cheung, Andrej Karpathy, Durk Kingma, and Pamela Vagata.[12] [13] [2] Advisors comprised Pieter Abbeel, Yoshua Bengio, Alan Kay, Sergey Levine, and Vishal Sikka, with Altman and Musk as co-chairs.[2] The initiative aimed to advance artificial general intelligence (AGI)—defined by OpenAI as systems surpassing humans at most economically valuable work—in a safe and beneficial manner, countering risks from profit-driven development that might prioritize commercial gains over long-term human welfare. OpenAI's official mission statement is: "Our mission is to ensure that artificial general intelligence benefits all of humanity." It does not mention sentience or consciousness. The OpenAI Charter outlines principles for this mission but also contains no references to sentience or consciousness.[2] Founders warned that corporate incentives could foster opaque competition and withhold safety research, potentially heightening existential risks from misaligned superintelligence.[14] [2] Musk, citing disputes with Google co-founder Larry Page—who viewed AI risks as overstated and labeled Musk a "speciesist"—sought to balance Google's approach through open collaboration, public findings, and safety-focused investments free from commercial pressures.[15][16] Founders pledged $1 billion collectively, including from Altman, Brockman, Musk, Reid Hoffman, Jessica Livingston, Peter Thiel, Amazon Web Services, Infosys, and YC Research; Musk contributed about $50 million, aided talent recruitment, and facilitated early Microsoft ties without personal gain, though actual donations started modestly and grew over time.[13] [12] [2][17][18] This non-profit structure insulated research from investor demands, emphasizing altruistic goals like aligning AGI with human values over self-interest.[14] [2] Musk later critiqued OpenAI's evolution into a for-profit, Microsoft-influenced entity as diverging from these ideals. Early work prioritized talent acquisition and infrastructure to integrate safety with capability advances.[2]Non-Profit Operations and Early Research (2016–2018)
OpenAI operated as a tax-exempt 501(c)(3) non-profit based in San Francisco, dedicated to advancing artificial general intelligence (AGI) for humanity's benefit.[19] Founders, including Elon Musk, Sam Altman, and Greg Brockman, pledged $1 billion in December 2015, but the organization received about $130 million in cash by 2019 per IRS filings, with Musk contributing roughly $44 million.[13] [20] By early 2017, it employed 45 researchers and engineers, focusing on open-source tools, publications, and safety measures to accelerate AI progress.[21] Initial efforts centered on reinforcement learning frameworks and AI safety. On April 27, 2016, OpenAI released the beta of OpenAI Gym, an open-source toolkit for standardizing RL algorithm benchmarks and enabling community experiments.[22] In June 2016, researchers published ["Concrete Problems in AI Safety"] (/page/Concrete_Problems_in_AI_Safety), which outlined key challenges in deploying RL systems, including safe exploration, robustness to shifts, side-effect avoidance, reward hacking prevention, and scalable oversight, based on observed AI behaviors.[23] In December 2016, OpenAI introduced Universe, a platform for AI agents to interact with diverse environments like games and browsers via virtual desktops, to gauge advances in general intelligence.[24] Starting in 2017, research expanded to multi-agent systems, supported by investments such as $7.9 million in cloud compute. OpenAI launched the OpenAI Five project, using five neural networks to master Dota 2—a game demanding long-term planning, imperfect information, and coordination amid 10,000 actions per turn. By June 2018, after training equivalent to 180 years of daily play, the agents matched amateur human teams in 5v5 matches.[25] At The International 2018, they won early games against professionals via quick reactions and strategy but lost later due to poor adaptation to human unpredictability, underscoring RL scalability limits without human input.[26] Outputs emphasized open-source dissemination and empirical validation over proprietary work, though funding limits strained compute-heavy efforts absent commercial drivers.[27]Shift to Capped-Profit Structure (2019)
In March 2019, OpenAI announced OpenAI LP, a capped-profit for-profit subsidiary controlled by its nonprofit parent, OpenAI Inc., to attract external capital for scaling AI research toward artificial general intelligence (AGI), which requires vast computational resources beyond philanthropic funding.[28][29] The model limited investor and employee returns to up to 100 times invested capital, with caps initially decreasing over time but revised to increase 20% annually from 2025; excess profits would return to the nonprofit for mission-aligned activities, such as safety research and technology dissemination.[28][30] This hybrid balanced competitive pressures in AI development with safeguards against profit maximization overriding safety and ethics.[29] The shift enabled expanded partnerships, particularly with Microsoft, which committed billions in cloud credits and investments for rapid scaling. Governance remained subordinate to the nonprofit board, which retained control and mission-aligned fiduciary duties, while allowing equity incentives for talent retention. Critics, including co-founder Elon Musk, contended that even capped profits risked mission drift, though OpenAI deemed the structure essential for AGI leadership.[28][31] In 2025, OpenAI evolved this framework: its nonprofit (renamed OpenAI Foundation) now oversees a for-profit public benefit corporation (OpenAI Group PBC) with conventional equity, eliminating prior caps to better attract capital while maintaining control and mission oversight.[3][20]Rapid Scaling and Key Partnerships (2020–2023)
In June 2020, OpenAI released GPT-3, a large language model with 175 billion parameters trained on Microsoft Azure supercomputing infrastructure, representing a substantial increase in scale from the 1.5 billion parameters of GPT-2.[32][33] This model enabled advanced natural language generation capabilities accessible via API, marking an early phase of rapid technical scaling through expanded compute resources provided by Microsoft, OpenAI's primary cloud partner since 2019.[34] By 2021, OpenAI deepened its partnership with Microsoft, securing an additional $2 billion investment to support further infrastructure and research expansion.[35] This funding facilitated releases such as DALL-E in January 2021 for image generation and Codex, which powered GitHub Copilot in collaboration with Microsoft's GitHub subsidiary, demonstrating applied scaling in multimodal AI tools. Revenue grew modestly to $28 million, reflecting initial commercialization via API access, while compute demands intensified reliance on Azure for training larger models.[36] The November 30, 2022, launch of ChatGPT, powered by GPT-3.5, triggered unprecedented user scaling, reaching 1 million users within five days and 100 million monthly active users by January 2023—the fastest growth for any consumer application at the time.[37][38] This surge drove revenue to approximately $200 million in 2022, necessitating massive infrastructure buildup on Microsoft Azure to handle query volumes exceeding prior benchmarks by orders of magnitude.[36] In January 2023, Microsoft committed a multiyear, multibillion-dollar investment—reportedly $10 billion—to OpenAI, entering the third phase of their partnership and designating Azure as the exclusive cloud provider for building AI supercomputing systems.[34][39] This enabled OpenAI to scale compute for next-generation models amid ChatGPT's momentum, with 2023 revenue reaching $1.6–2.2 billion, primarily from subscriptions and enterprise API usage, while highlighting OpenAI's growing dependency on Microsoft's infrastructure for sustained expansion.[36][40]Breakthrough Models and Ecosystem Expansion (2024)
In 2024, OpenAI released GPT-4o on May 13, a multimodal model that processes and generates text, audio, and vision inputs in real time, advancing integrated reasoning across modalities.[41] It enables emotional expression in voice interactions, matches or exceeds GPT-4 Turbo on multilingual benchmarks like MGSM per OpenAI evaluations, and achieves about 320 milliseconds voice latency in tests.[41] GPT-4o initially launched for paid ChatGPT users, with text and image support soon extended to free users alongside data analysis and file uploads.[42] On July 18, OpenAI launched GPT-4o mini, a cost-efficient version that replaced GPT-3.5 Turbo as the default for many ChatGPT interactions, cutting costs by 60% while sustaining strong evaluation performance. This model increased accessibility for developers and high-volume uses, enabling wider API adoption without matching cost rises.[43] On September 12, OpenAI previewed the o1 series, which enhances reasoning via extended "thinking" time for multi-step tasks in mathematics, coding, and science, per OpenAI claims.[44] o1-preview and o1-mini outperformed GPT-4o on benchmarks including AIME (83% accuracy) and Codeforces, though requiring more computation.[45] The full o1 followed on December 5, adding image analysis and reducing errors by 34% in certain tasks, with integration into ChatGPT Pro.[46] These advances supported ecosystem growth, including a $6.6 billion funding round on October 2 at $157 billion post-money valuation to expand infrastructure and research.[47] OpenAI updated developer tools with o1 API access and optimizations by December 17, facilitating custom applications and agent workflows.[48] Enterprise integrations advanced, as GPT-4o enabled real-time features in partner platforms, while the GPT Store and custom GPTs gained traction as a third-party marketplace.[49] OpenAI positioned itself as a broader AI platform, combining proprietary models with API incentives, yet high compute needs posed scalability challenges for smaller actors.[50]Infrastructure Buildout and New Releases (2025)
In May 2025, OpenAI acquired io Products, Inc., the AI hardware startup founded by former Apple design chief Jony Ive, in a deal valued at approximately $6.4 billion to integrate advanced product design expertise.[51][52] In 2025, OpenAI accelerated infrastructure expansion via the Stargate project, a joint venture with Oracle and SoftBank targeting up to 10 gigawatts of capacity by year-end, backed by a $500 billion commitment.[53] The project progressed ahead of schedule, announcing five additional sites on September 23, including a $15 billion "Lighthouse" campus in Port Washington, Wisconsin, with Oracle and Vantage Data Centers, expected to deliver nearly one gigawatt of AI capacity and over 4,000 construction jobs.[53][54] OpenAI also partnered with Oracle for up to 4.5 gigawatts of U.S.-based Stargate capacity in July, committing $300 billion over five years to Oracle's infrastructure.[55][56] To support this buildout, OpenAI formed hardware partnerships, including a September 22 agreement with NVIDIA for at least 10 gigawatts using millions of systems; an October 6 multi-year deal with AMD for six gigawatts of Instinct GPUs starting in 2026; and an October 13 collaboration with Broadcom for AI accelerator and network racks from mid-2026 to 2029.[57][58][59] These efforts extended to expansions in the UK and UAE, with analysts projecting $400 billion in infrastructure funding needs over the next 12 months and $50-60 billion annually for capacity exceeding two gigawatts by late 2025.[60][61] In October 2025, OpenAI restructured its for-profit entity into the OpenAI Group public benefit corporation (PBC) under the nonprofit OpenAI Foundation, which retains significant equity.[20] By late 2025, total funding raised exceeded $57 billion across multiple rounds.[62] Amid scaling, OpenAI released advanced models and tools. On January 31, it launched o3-mini, a cost-efficient reasoning model for coding, math, and science.[63] This preceded o3 and o4-mini on April 16, with o3-pro for Pro users on June 10; o3 topped benchmarks like AIME 2024 and 2025.[64] GPT-5 debuted August 7 as OpenAI's strongest coding model, excelling in front-end generation and debugging large repositories.[6] On August 5, open-weight models gpt-oss-120b and gpt-oss-20b were introduced for lower-cost access, matching certain ChatGPT tasks.[65] August 28 brought gpt-realtime and updated Realtime API for speech-to-speech processing.[66] October 21 saw ChatGPT Atlas, an AI-powered web browser integrated with its chatbot.[67] GPT-5.1 followed on November 12 with Instant and Thinking variants, plus Pro tiers for reasoning and customization.[68] GPT-5.2 launched December 11 with gains in intelligence, long-context understanding, and agentic tasks, followed by GPT-5.2-Codex on December 18 for coding.[69] The GPT-5 series introduced around 12 new models over six months, spanning chat, thinking, pro, and codex versions.Organizational Structure and Leadership
Key Executives and Personnel
OpenAI's founding team in December 2015 included Sam Altman, Greg Brockman, Ilya Sutskever, Wojciech Zaremba, and Elon Musk, who co-chaired with Altman. Musk departed in 2018 amid disagreements over control and direction.[70] Sam Altman has served as CEO since 2019, following his role as president of the initial nonprofit; he was briefly ousted and reinstated in November 2023 after a board vote citing lack of candor, involving Sutskever.[71][72] Greg Brockman, co-founder and former Stripe CTO, is president and chairman, directing strategic and technical operations; he took a sabbatical through late 2024, returning by November.[71][73] Jakub Pachocki replaced Sutskever as chief scientist in May 2024; Sutskever, a co-founder who advanced the GPT series, left after nearly a decade, having joined the 2023 board action against Altman.[74][75] Brad Lightcap serves as chief operating officer, handling business operations and partnerships.[71] Mira Murati was CTO until late 2024, then departed to establish Thinking Machines Lab in early 2025, securing $2 billion funding.[76] Other key figures include co-founder Wojciech Zaremba, focused on research; Fidji Simo, CEO of Applications since May 2025; Vijaye Raji, CTO of Applications post-September 2025 Statsig acquisition; Mark Chen, promoted to chief research officer in March 2025; and Barret Zoph, who rejoined in January 2026 to lead enterprise sales efforts.[77][78][79][80] These transitions underscore OpenAI's move from research nonprofit to commercial scale, with elevated turnover in research and safety teams since 2024, including significant departures of key researchers, executives, and AI safety staff. In 2025, over 25% of key research talent—more than 50 staffers—left, with many poached by Meta, such as Shengjia Zhao, Hongyu Ren, and Jiahui Yu, contributors to GPT-4 and o1 models.[70][81][82] These exits were linked to leadership style, tensions between safety and product priorities, governance concerns, and repercussions from the 2023 Altman ouster and reinstatement. However, no reliable sources indicate these events negatively impacted model quality; OpenAI released advanced models like o1 in 2024, and AI performance benchmarks showed sharp improvements in 2025 per the Stanford AI Index.[83]Governance: Nonprofit Board and Investor Influence
OpenAI's governance is directed by the board of directors of its nonprofit entity, the OpenAI Foundation, a 501(c)(3) organization founded in 2015 that maintains ultimate control over the for-profit arm, now the OpenAI Group public benefit corporation (PBC) after a transition in October 2025.[20] The nonprofit board holds fiduciary responsibility to advance the mission of developing artificial general intelligence (AGI) that benefits humanity, with authority to oversee, direct, or dissolve the for-profit arm if it deviates; the Foundation owns about 26% equity in the PBC.[20] As of May 2025, the board includes independent directors such as Chair Bret Taylor, Adam D'Angelo, and others with expertise in technology, policy, and safety, excluding OpenAI executives for impartiality.[20] This setup prioritizes long-term societal benefits over short-term profits but has drawn criticism for potential inefficiencies in commercial scaling.[84] The board's authority was evident in November 2023, when it removed CEO Sam Altman on November 17 due to concerns about his inconsistent candor, which hindered oversight.[85] This move by a small board, including Ilya Sutskever and Helen Toner, highlighted tensions between safety priorities and commercialization, leading to employee threats of departure and Altman's reinstatement five days later with a new board featuring Taylor as chair, D'Angelo, and Larry Summers.[86] Later changes added Altman in March 2024 and Adebayo Ogunlesi in January 2025, along with commitments to independent audits.[87][88] Investor influence, mainly from Microsoft—which invested about $13 billion since 2019 and provides exclusive cloud services via Azure—lacks formal board seats or veto rights to preserve nonprofit control.[89][90] Yet during the 2023 crisis, Microsoft's leverage appeared through negotiations for technology access and staff recruitment threats, revealing practical influence despite safeguards against profit-driven decisions. This preserved the governance model but fueled debates on balancing growth with AGI risks, with some linking board actions to the ouster's consequences.[91]Financials and Corporate Structure
OpenAI operates under a hybrid structure: a non-profit parent company, OpenAI, Inc., a 501(c)(3) founded in 2015, overseeing a for-profit subsidiary, OpenAI LP, established in 2019, with a historically capped-profit model limiting investor returns to 100 times the initial investment, excess profits directed to the non-profit to advance the AGI mission.[20] In September 2024, OpenAI announced plans to restructure the for-profit entity into a public benefit corporation, removing the profit cap to raise more capital for AGI development. This setup supports commercial activities while aligning with the non-profit's mission. The hybrid model facilitates capital attraction for AI development and applies to compensation via Profit Participation Units (PPUs), which vest over four years and share profits without purchase requirements, though the cap hinders standard valuations.[92] Major funding includes a 2015 $1 billion pledge yielding $130 million; Microsoft's investments of $1 billion (2019), $2 billion (2021), and $10 billion (2023); a late-2023 valuation of $90–100 billion; a 2024 $6.6 billion round and a secondary tender offer completed in November 2024, both at a $157 billion valuation.[93][94] Separate reports indicate NVIDIA is nearing a $20 billion investment in OpenAI's current funding round.[95] OpenAI is a private company and does not have a publicly traded stock price. Reports from 2025 suggested discussions for valuations exceeding $300 billion, but these remain unconfirmed, with no newer funding rounds or valuations publicly disclosed as of early 2026. OpenAI has no current plans for an initial public offering (IPO), preferring private funding rounds at high valuations. This valuation trajectory stems from generative AI demand, enterprise uptake, and funding momentum.[96] As a private entity, OpenAI forgoes audited financials, relying on industry estimates for revenue. Annualized recurring revenue exceeded $20 billion by end-2025, growing from $2 billion in 2023, fueled primarily by ChatGPT subscriptions (Plus, Team, Enterprise) and API access, with enterprise offerings serving as a major growth driver for large organizations, alongside ChatGPT (800 million weekly active users), enterprise integrations serving over 1 million customers, model enhancements boosting engagement, and developer tools.[97]Business Strategy
OpenAI's core strategy centers on achieving artificial general intelligence (AGI) to benefit humanity, entailing substantial investments in compute infrastructure and research to drive advancements toward this goal.[98]Geopolitical Positioning, Including Stance on China
OpenAI positions itself as advancing U.S. technological leadership in global AI competition, complying with U.S. export controls by restricting access to its technologies in countries like China, Russia, and Iran to safeguard national security and prevent misuse by foreign governments.[99] [100] This aligns with U.S. policy to maintain AI primacy against risks from adversarial states.[101] OpenAI enforces strict access limits in China, blocking services for mainland users since mid-2024 and disrupting accounts tied to Chinese government entities in 2025 that sought to use its models for surveillance, malware, phishing, and influence operations, including monitoring Uyghur dissidents.[99] [100] [102] [103] [104] These measures, outlined in OpenAI's threat intelligence reports, reflect a stance against AI weaponization by Beijing, with commitments not to aid foreign suppression of information.[105] CEO Sam Altman has highlighted China's competitive threat, warning in August 2025 that the U.S. underestimates Beijing's AI progress and independent scaling capabilities.[101] [106] He views U.S. chip export controls as insufficient against China's self-reliance, advocating nuanced strategies, and contrasts democratic AI development with autocratic models.[107] [108] [109] In 2025, OpenAI launched the "OpenAI for Countries" initiative, providing customized AI infrastructure and training to allies pursuing "sovereign AI" under U.S. standards, countering China's open-source model distribution in the Global South to foster Western-aligned ecosystems.[110] [111] [112]Commercial Partnerships and Infrastructure Investments
OpenAI's primary commercial partnership with Microsoft began with a $1 billion investment in 2019, expanding to approximately $13 billion by 2023 and providing exclusive Azure access for model training and deployment.[34][113] This enables enterprises to access advanced AI models, such as the GPT series, securely via Azure OpenAI Service, offering enterprise-grade security, data privacy (customer data not used to train models), compliance certifications, scalability, and seamless integration with Azure tools for building AI applications.[114] This evolved in 2025, with Microsoft retaining major investor status as OpenAI diversified compute resources through non-exclusive deals amid rising demands; the restructuring included OpenAI's commitment to purchase an additional $250 billion in Azure services, extending Microsoft's exclusive API access and IP rights through 2032 (with exclusivity until AGI is achieved).[115][116][117] In 2026, the partnership drove significant growth for Azure, with Microsoft reporting $51.5 billion in cloud revenue for Q2 FY2026.[118] OpenAI announced several enterprise partnerships in 2025 to embed its models in business applications, including expansions with Salesforce for AI-enhanced CRM (October 14), integrations with Spotify and Zillow, a hardware-software alliance with Samsung (October 1), and a $1 billion Disney deal (December 11) licensing over 200 characters from Disney, Marvel, Star Wars, and Pixar to boost Sora video generation.[119][120][121][122][123] These initiatives, featured at DevDay 2025, emphasize developer tools and integrations to expand beyond consumer use.[124] OpenAI launched the Stargate project in 2025 as a nationwide AI data center network, partnering with Oracle and SoftBank for up to 4.5 gigawatts via a $300 billion power-optimized agreement; plans target 7 gigawatts across $400 billion facilities, with Texas as a key hub.[125][53][126][127] By September 23, five U.S. sites were announced, including a $15 billion-plus Wisconsin campus with Oracle and Vantage Data Centers approaching 1 gigawatt.[128][129] In January 2026, OpenAI partnered with SoftBank Group and SB Energy ($1 billion investment for multi-gigawatt centers, including a 1.2 gigawatt site in Milam County, Texas); issued a January 15 RFP for domestic AI supply chain manufacturing; and introduced the Stargate Community plan to fund dedicated power resources, avoiding local energy cost hikes in sites across Texas, Wisconsin, and Michigan.[130][131][132] To acquire compute hardware, OpenAI secured letters of intent for massive deployments: 10 gigawatts of NVIDIA systems (September 22, millions of GPUs, up to $100 billion); a multi-year AMD deal for 6 gigawatts of Instinct GPUs (October 6, starting 1 gigawatt in 2026); and Broadcom's 10 gigawatts of custom accelerators (October 13).[57][58][59] These exceed $1 trillion in aggregate value, enabling independent scaling beyond providers like Microsoft Azure.[56][133] The September 2025 strategic partnership with NVIDIA, under which the company intended to invest up to $100 billion progressively in exchange for OpenAI deploying at least 10 gigawatts of NVIDIA systems for AI infrastructure, has stalled as of February 2026. No contracts have been signed, and no funds have been exchanged, with reports citing doubts about OpenAI's business model and limited progress toward the first gigawatt deployment scheduled for late 2026.[134][135] NVIDIA CEO Jensen Huang denied any drama on February 3, 2026, stating the plan remains on track and expressing interest in investing in OpenAI's next funding round.[136][137]Core Technologies and Products
Foundational Models: GPT Series Evolution
The GPT series, started by OpenAI in 2018, includes large language models pre-trained unsupervised on massive text data, then fine-tuned for specific tasks. This approach enables emergent abilities like zero-shot learning and few-shot learning. Early models scaled size and data to boost coherence and generalization in NLP tasks; later versions added multimodal inputs, longer context windows, and reasoning mechanisms.[138] Post-GPT-3, parameter counts and training details grew less transparent amid competition, but benchmarks show gains in perplexity, factual accuracy, and instruction-following.[139]| Model | Release Date | Parameters | Key Capabilities and Innovations |
