The exit of AI researcher Andrew Tulloch adds another data point to what has become one of the costliest hiring contests in tech history. Meta, Anthropic, OpenAI and Google are all competing for a small pool of researchers seen as capable of pushing frontier AI forward, and that competition has pushed compensation packages to levels once unheard of outside professional sports or corporate boardrooms. Tulloch's departure is notable less for the dollar figure alone than for the timing: Meta had only just re-recruited him from his own startup a matter of months earlier, a reminder that even a nine- or ten-figure package doesn't guarantee lasting loyalty in a market this competitive.Key HighlightsAbout The AuthorI love telling stories about technology that actually matter. I enjoy going beyond specs and buzzwords to understand how tech is changing the way we live, work and connect. I started my journalism journey in 2015, and over the years, I’ve learned that the best tech stories are not always about the newest gadget, but about why it matters to you.The Departure: Andrew Tulloch has resigned from Meta, reportedly delaying his exit until after the successful launch of the company's new open-source AI models and Muse assistant.The Price Tag: Reports indicate Tulloch was offered a compensation package worth up to $1.5 billion over six years, which would make him one of the highest-paid employees in tech history.Strategic Role: Tulloch worked within Meta's TBD superintelligence lab, a division central to CEO Mark Zuckerberg's AI strategy and led by Scale AI founder Alexandr Wang.The Next Move: Industry sources suggest Tulloch is now heading to rival AI laboratory Anthropic, continuing the high-profile circulation of top-tier AI talent between major tech firms.Meta is losing one of its most high-profile artificial intelligence researchers less than a year after orchestrating his return to the company. Andrew Tulloch has reportedly resigned from the tech giant and is expected to join rival AI laboratory Anthropic.Tulloch’s departure marks a significant blow to Meta’s superintelligence ambitions, particularly given the extraordinary financial commitment the company reportedly made to secure his expertise. According to multiple industry reports, Tulloch was offered a compensation package valued at up to $1.5 billion over six years.Who is Andrew Tulloch?Andrew Tulloch is widely recognised as one of the most prominent researchers in the artificial intelligence field. His career has largely focused on the development and deployment of large-scale machine learning systems.Before his most recent stint at Meta, Tulloch spent 11 years at the company. He departed in 2023 to co-found Thinking Machines Lab, an AI startup established alongside former OpenAI Chief Technology Officer Mira Murati and other notable industry figures. The startup rapidly gained traction, reportedly reaching a valuation of $12 billion in a recent seed funding round.Meta successfully poached Tulloch back from his own startup several months later, a move that underscored the company's determination to consolidate top-tier talent for its long-term AI roadmap.More articles by AuthorTrending StoriesThe $1.5 Billion Question: What Meta SpentThe reported $1.5 billion compensation figure has drawn intense scrutiny. While the exact structure of the package has not been officially disclosed by Meta, such historic valuations in the tech industry are typically heavily weighted towards equity and performance-based stock grants vesting over several years, rather than direct cash salaries.Even if the final realised value falls short of the headline figure, the initial offer alone positions Tulloch among the most highly compensated employees in the history of the technology sector. It serves as a stark indicator of the premium that major technology firms are willing to pay for researchers capable of advancing artificial general intelligence (AGI).The TBD Lab and the Timing of the ExitDuring his recent tenure, Tulloch worked within Meta’s TBD lab. This division operates as the centre of CEO Mark Zuckerberg’s ambitious superintelligence strategy and is spearheaded by Scale AI founder Alexandr Wang.According to sources briefed on the matter, Tulloch strategically delayed his departure. He reportedly remained with the company to ensure the successful launch of Meta’s newest family of open-source AI models and its AI assistant, Muse, which was announced earlier this week. This suggests an orderly, planned transition rather than an abrupt departure.The Revolving Door of AI TalentTulloch’s anticipated move to Anthropic highlights a broader industry trend. With the artificial intelligence race accelerating, the highly specialised skills possessed by elite researchers are in extreme demand. Talented engineers and scientists frequently move between leading laboratories, including Anthropic, OpenAI, Google, and Meta.Researchers of Tulloch’s calibre possess the rare ability to command top-tier salaries at incumbent tech giants or raise billions in venture capital to launch their own ventures, mirroring the trajectories of figures like OpenAI’s Ilya Sutskever or Google’s Jeff Dean.The central question for the industry is how long this high-priced revolving door will persist. As the talent pool gradually expands and the initial frenzy of the AI boom stabilises, market dynamics may eventually adjust. Until then, companies like Meta and Anthropic will continue to compete fiercely, and expensively, for the architects of the next generation of artificial intelligence.Read Also FAQsWho is Andrew Tulloch and what contributions has he made to the AI field?Andrew Tulloch is a prominent AI researcher known for his work in developing and deploying large-scale machine learning systems.
