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).
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When the administration partially rescinded the directive on June 26, 2026, clearing vetted firms and agencies to regain access to Mythos 5, Commerce Secretary Howard Lutnick addressed his letter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).
