Tom Brown is a co-founder and the chief compute officer of Anthropic, where he is responsible for the compute infrastructure and technical operations behind the Claude models. He co-founded Anthropic in 2021 alongside Dario Amodei, Daniela Amodei, Jared Kaplan, Jack Clark, and others (Source: bloomberg.com; Source: neuronfeed.com).
Background
Before co-founding Anthropic, Brown worked at OpenAI, where he was the lead author of the 2020 paper introducing the GPT-3 language model, "Language Models are Few-Shot Learners" (Source: forbes.com). He studied computer science at the Massachusetts Institute of Technology (Source: forbes.com; Source: linkedin.com). At Anthropic he leads the team responsible for the compute stack — the training and serving infrastructure underpinning Claude — a role reflected in his title of chief compute officer (Source: neuronfeed.com; Source: bloomberg.com). Bloomberg's Billionaires Index lists Brown among Anthropic's co-founders following the company's 2026 funding round (Source: bloomberg.com).
Brown appears as an author on several of the foundational papers of the scaling era. He is among the ten authors of Scaling Laws for Neural Language Models (January 2020), the OpenAI paper that established the power-law relationship between model performance and compute, data and parameters (Scaling Laws for Neural Language Models). At Anthropic he is listed on the 26-author In-context Learning and Induction Heads (March 2022) (In-context Learning and Induction Heads (Olsson et al., Anthropic, 2022)) and among the senior authors of the Constitutional AI paper (Constitutional AI: Harmlessness from AI Feedback).
Compute leadership at Anthropic
Brown's compute organization has drawn senior recruits during 2026. On July 13, 2026, Monzo co-founder Tom Blomfield said he was taking a leave of absence from Y Combinator to join Anthropic's compute team under Brown, citing "the early stages of recursive self-improvement" (Source: businessinsider.com). When OpenAI announced on August 28, 2026 that it would end its partnership with Cursor following the coding tool's acquisition by SpaceX, Brown said within hours that Anthropic planned to increase compute to support Claude models in Cursor (Source: reuters.com).
Role in the 2026 export-control negotiations
Brown became Anthropic's lead interlocutor with the Trump administration during the June 2026 dispute over U.S. export controls on Anthropic's most capable models. Reporting published June 24, 2026 said Anthropic had replaced Dario Amodei with Brown in its White House meetings over re-releasing Fable 5, after administration officials signaled they found Amodei difficult to deal with; The Verge reported that Brown, alongside policy chief Sarah Heck, handled the Washington negotiations while Anthropic kept its Mythos-class models offline (Source: wired.com; Source: theverge.com).
When the administration partially rescinded the directive on June 26, 2026, clearing vetted firms and agencies to regain access to Mythos 5, Commerce Secretary Howard Lutnick addressed his letter conveying the decision to Brown as Anthropic's chief compute officer, writing that the company had made "significant progress" addressing the government's concerns (Source: politico.com; Source: scmp.com). The broader episode is documented under Export Controls (AI).
Appearances at government events
G20 innovation ministerial
Brown was Anthropic's representative at the G20 innovation ministerial co-hosted by the United States in Chapel Hill, North Carolina, on September 1–2, 2026. Reuters reported on September 1 that a company spokesperson said Brown was slated to address the group on the second day, alongside OpenAI's Sam Altman and Nvidia's Jensen Huang, after White House adviser Michael Kratsios had urged delegates on the first day to adopt what he called the "Carolina Principles" against writing entirely new AI-specific regulations (Source: reuters.com). Axios reported that Commerce Secretary Howard Lutnick was to interview Brown on stage on September 2 (Source: yahoo.com). The content of Brown's remarks was not available at the time of writing.
White House National Design Studio launch event
Invitation materials obtained by CBS News list Brown, identified as Anthropic co-founder, among the special guests at an all-day White House event at the Andrew W. Mellon Auditorium in Washington on September 29, 2026, alongside Elon Musk, Jensen Huang and Palantir chief technology officer Shyam Sankar; the agenda includes afternoon panels on artificial intelligence, energy and space, and the event is to include the launch of the National Design Studio's America.gov website (Sources: cbsnews.com; foxnews.com). CBS News notes that the event came as executives at Anthropic and OpenAI had in recent weeks called for limits on the speed of AI development.
