Mark Zuckerberg

Mark Zuckerberg has championed broadly available AI models at Meta and, with Priscilla Chan, made AI and biology a central focus of their philanthropy. His consequential choices include expanding Llama’s developer ecosystem, directing Meta toward personal AI agents, and supporting institutes that combine biological measurement with model development. He founded Facebook in 2004 and is Meta’s chairman and CEO.[2][3][4][1]ⁿ¹

In his July 23, 2024 essay, Open Source AI is the Path Forward, Zuckerberg accompanied the release of Llama 3.1’s 405B, 70B and 8B models with an argument for developer control. Organizations should be able to train and fine-tune models with private data, distill them into smaller models, and choose where to run them. He argued that this reduces dependence on providers that can change models, alter terms, or withdraw service.[3]

Zuckerberg described a change from developing Llama internally and then releasing it to building teams and partnerships expressly to support adoption. His rationale extended beyond the models: a wider ecosystem could supply tools, efficiency improvements, silicon optimizations and integrations. He also argued that releasing Llama fit Meta’s business because “selling access to AI models isn’t our business model.”[3]

He identified building Meta’s services under Apple’s platform constraints as a formative experience behind his support for open AI and AR/VR ecosystems. In his account, platform rules, developer fees and blocked innovations limited what Meta could build. His claim that open AI would be safer rested on transparency and broad scrutiny, alongside more capable institutions checking malicious actors.[3]

In his July 30, 2025 Personal Superintelligence letter, Zuckerberg set out a vision of AI directed toward individuals’ chosen goals, relationships and creative projects. He predicted that glasses able to see and hear a user’s surroundings would become primary computing devices. Broad access came with a qualification: novel safety concerns required Meta to be “careful about what we choose to open source.”[4]

His August 10, 2026 essay, The Future is for Everyone, defined personal-agent alignment as serving a person’s goals and values within legal and safety boundaries. He argued that widely distributed agents could check competing concentrations of power. As concrete examples, he described his own agent flagging information, helping prototype ideas, and planning recipes and ordering ingredients for weekend baking with his daughter.[5]

Zuckerberg also announced that Meta was implementing a governance structure giving its independent board authority to approve model-release safety criteria and review whether releases met them. He said he should not be the sole decision-maker on deploying superintelligence. The announcement described an arrangement being implemented, rather than completed release reviews.[5]

Zuckerberg’s philanthropy with Priscilla Chan began before Meta’s recent AI initiatives. Zuckerberg and Chan started CZI roughly a decade before their November 2025 interview; Chan described their complementary backgrounds as a physician and an engineer. Zuckerberg said their initial work included education and community support, but that science and Biohub would become the main focus of their philanthropy.[1]

Zuckerberg’s Biohub explanation emphasized operating institutes as well as funding grants. He argued that scientific tools can require a 10–15-year runway and hundreds of millions of dollars, leaving room for philanthropy to support work poorly served by shorter funding cycles. He framed the mission as enabling other scientists: “Because we’re not actually curing the diseases.”[1]

Physical proximity was part of that institutional design. Zuckerberg recalled placing teams next to one another to improve collaboration at both Meta and Biohub, and said the first Biohub enabled more collaboration among Stanford, UCSF and Berkeley scientists and engineers. In November 2025, he described combining Biohub’s existing model team with Evolutionary Scale’s researchers and having Alex Rives run the program in partnership with leading biologists.[1]

His proposed technical approach was hierarchical modeling: understanding proteins and their interactions supports modeling cells, which in turn supports modeling systems such as immunity. He envisioned eventually merging virtual-cell models covering different data dimensions into a “biological omni model.” The aim was positive transfer—making capabilities stronger through integration—and he repeatedly characterized the work as early.[1]

Zuckerberg described models generating hypotheses for scientists to select and test, with results fed back into the models. Chan supplied the experimental mechanism: run a wet-lab experiment, compare its outcome with the prediction, and use that feedback to improve accuracy. Zuckerberg also advocated generating some biological datasets specifically to train better models, stressing that intelligence cannot replace missing empirical knowledge. He presented this as one approach to science, and declined to assign a new date for curing or preventing all diseases.[1]

Earlier Facebook decisions provide context for Zuckerberg’s later views on platform control and responsibility. Before the Llama releases, he publicly acknowledged failures in protecting users’ information and committed the company to building a new computing platform.[8][7]

In an April 4, 2018 press call addressing Cambridge Analytica and developer data access, Zuckerberg acknowledged that Facebook had taken too narrow a view of its responsibility: “It was my mistake.” He described investigations of apps with extensive data access and tighter restrictions, crediting Ime Archibong and Mike Schroepfer with follow-up changes including renewed authorization for unused apps. Groups and Events APIs were also being restricted to better protect other people’s information.[8]

On October 28, 2021, Zuckerberg announced the Meta name and committed the company to the metaverse, whose defining quality he described as a feeling of presence with other people or in another place. He called for privacy, safety, open standards and interoperability from the outset, and outlined plans for subsidized hardware and continued support for side-loading and PC streaming. These were stated commitments for a future platform, preceding his later AI strategy.[7]
