Early life and education

Early years

Adam Cheyer was born c. 1966 in , . He grew up in , a small town without stoplights, where his childhood was marked by boredom that spurred creativity and imagination, limited as it was to just one hour of per week. As a child, Cheyer dreamed of becoming a magician, an interest that instilled in him a sense of wonder, curiosity, and the thrill of achieving the seemingly impossible. This fascination with magic influenced his approach to problem-solving, as he later reflected that "entrepreneurs and magicians are exactly the same—they imagine a desirable, impossible future that doesn't exist, and then they work backward from that vision to figure out the math and science to make it come true." He was also inspired by his grandfather's worldly perspective, which encouraged a global outlook on life. During high school at Sharon High School, Cheyer discovered a passion for computer science, mathematics, science, and reading, viewing computer science as the singular field he wanted to pursue. From his freshman year, he began working on numerous technical projects and small inventions, honing his skills in programming and technology. It was during this period that he developed a life philosophy of setting verbally stated goals and continuously striving to achieve more each year, a mindset that guided his formative years. These early experiences in technology and self-directed innovation paved the way for his entry into higher education at Brandeis University.

Research at SRI International

Following his in from the in 1993, Adam Cheyer joined as a . Prior to this, he had served as a senior software engineer at Bull S.A. from 1987 to 1992, where he implemented the core inference engine for NOEMIE, an tool for automating hardware and software configurations across over 30,000 parts. At , Cheyer held several key positions within the Artificial Intelligence Center, contributing to advanced research in and human-computer interaction. He served as co-director of the Computer Human Interaction Center in 1999, directing a team of 11 staff and eight visiting researchers focused on mediated spaces integrating applications for home, car, and office environments. Later, from 2003 to 2008, he acted as Program Director, managing multimillion-dollar projects on distributed agent architectures and user interfaces, including the invention of "Delegated Computing." As Chief Architect of the CALO (Cognitive Assistant that Learns and Organizes) project from 2003 onward, Cheyer led the integration of AI technologies from 25 institutions in what was DARPA's largest initiative, funded at $150 million over five years as part of the Personalized Assistant that Learns (PAL) program. The project's primary goals were to develop cognitive software systems capable of reasoning, learning from experience, receiving instructions, explaining their actions, reflecting on learned knowledge, and handling unexpected situations robustly—aiming to support decision-making in uncertain environments. This work built on earlier efforts at SRI, such as the Open Agent Architecture (OAA), a framework for coordinating distributed software agents to perform complex tasks collaboratively. CALO's technologies were designed to transition into practical applications under the PAL framework, focusing on personalized assistants for and organizational use. During his tenure at SRI, spanning over a decade across multiple periods, Cheyer co-authored more than 60 peer-reviewed publications and contributed to 27 issued patents related to intelligent agents, multimodal interfaces, and cognitive systems, with key examples including foundational work on the OAA and semantic desktops like IRIS.

Viv Labs aimed to enable third-party developers to build and integrate AI capabilities seamlessly, fostering an extensible ecosystem for complex user interactions. Viv was designed as a next-generation AI assistant capable of handling sophisticated, context-aware queries through a breakthrough in dynamic program generation. This technology allowed the system to interpret and automatically synthesize executable code on the fly to accomplish tasks, such as coordinating across multiple services without predefined scripts. For instance, Viv could generate a multi-step program in milliseconds to fulfill requests like booking a reservation while checking weather and traffic conditions. This approach emphasized adaptability and openness, positioning Viv as a foundational platform for embedding conversational AI in diverse applications. Samsung announced its acquisition of Viv Labs on October 5, 2016, for a reported $215 million, with the deal integrating the startup's technology as the core of its Bixby voice assistant. The acquisition enabled Samsung to bolster its AI offerings, moving away from reliance on third-party assistants and toward a proprietary, developer-friendly system. Viv's platform formed the basis for Bixby's advanced capabilities, including and task automation across Samsung's ecosystem. Following the acquisition, Cheyer joined as Vice President of Research and Development, where he led the integration of Viv's technology into Bixby and oversaw its product engineering. Under his guidance, Bixby was deployed starting in March 2017 with the Galaxy S8 and S8+ smartphones, initially focusing on vision and contextual awareness before incorporating full Viv-powered voice features in July 2017. Bixby 2.0, which more deeply embedded dynamic program generation from Viv, launched in October 2017 and expanded to devices like the Galaxy Note9, refrigerators, and smart TVs, reaching over 500 million units worldwide.
