Soumith Chintala, creator of PyTorch and a pillar of Meta’s AI revolution, has joined Mira Murati at Thinking Machines Lab, intensifying the global race for top AI talent and reshaping the future direction of open-source machine learning tools.
The Talent That Built PyTorch Shifts to Thinking Machines
Soumith Chintala is a household name in the machine learning world. As the principal creator of PyTorch, the open-source AI framework that underpins research and production systems at companies from Tesla to Uber and academic labs worldwide, his decisions set the pace for modern AI. After more than a decade at Meta, Chintala has now joined Thinking Machines Lab—the ambitious AI startup founded by former OpenAI CTO Mira Murati [Business Insider].
This move comes just weeks after Chintala bid farewell to Meta and the PyTorch project, ending an era for both Meta’s AI research and the open-source community. His choice reflects a seismic shift as top-tier talent inside tech giants are now betting on fast-moving startups—and staking a claim in the next wave of artificial intelligence innovation.
Why Chintala’s Move Matters: Implications for Developers and the AI Ecosystem
For developers and AI researchers, Chintala’s journey is about much more than one individual changing jobs. Under his leadership, PyTorch evolved from an internal Facebook project to the world’s most popular deep learning library, used for applications from self-driving vehicles to advanced language models. His continued focus on usability, modularity, and active community engagement have made PyTorch synonymous with practical, production-ready AI.

- The talent shift also tees up a new round of platform battles, as the lines blur between open source, proprietary models, and hybrid solutions for real-world business use.
Thinking Machines Lab: The New Magnet for Elite AI Talent
Launched in early 2025 and built around the vision of human-AI collaboration, Thinking Machines Lab has rapidly become one of the most closely watched players in the AI space. Founder Mira Murati wasted no time assembling a world-class bench of industry leaders, including John Schulman (co-creator of ChatGPT), Alec Radford, and Bob McGrew (ex-OpenAI CRO).
The company’s aggressive recruiting has been matched by blockbuster funding rounds: in just months, it raised $2 billion at a $10 billion valuation, and is now reportedly in talks to push that figure to $50 billion in its next round [Bloomberg]. To secure technical talent, Thinking Machines has offered compensation packages topping $500,000—a clear bet that elite researchers are the new strategic currency for the AI platform wars [Business Insider].
Inside Meta’s AI Restructuring—and What It Means for Open Source
Chintala’s departure is the latest in a series of major shifts at Meta. Over the past year, Meta has reorganized its sprawling AI division, recruiting dozens of high-profile figures from across the industry and creating a new Superintelligence Labs group. Notably, the group’s leadership now includes Alexandr Wang, formerly Scale AI’s CEO, as Meta pursues even more aggressive goals in advanced research and product velocity [Business Insider].
The open-source future of AI, embodied by projects like PyTorch, hangs in the balance. With Chintala’s exit and Meta’s evolving approach, the ecosystem could see a redistribution of open-source leadership, further accelerating the rise of startups as primary engines of innovation.
User, Researcher, and Community Reactions
Within the developer and researcher community, Chintala’s move is cause for both optimism and acute interest. For years, requests have poured in for more user-friendly model fine-tuning, greater support for running large language models outside big corporate clouds, and more accessible, transparent tools. Thinking Machines Lab is already piloting Tinker, a tool for fine-tuning large language models, with early customers at Princeton and Stanford. There’s an expectation that this user-centric, researcher-driven approach will make high-performance AI customization accessible to more organizations.
- With such a concentration of open-source expertise, Thinking Machines Lab could soon set the new standard for collaborative AI R&D beyond Silicon Valley’s biggest players.

What’s Next: Will Open Source Remain at the Center of AI?
The question facing the AI dev community: will Chintala help Thinking Machines Lab remain deeply committed to open platforms, or could the gravitational pull of business incentives drive the new wave of AI research behind closed doors?
Chintala’s track record suggests a continued focus on openness. In his PyTorch farewell, he noted the project’s profound reach—powering classrooms worldwide and production systems across industries. That rare balance of developer productivity and scientific rigor is what the AI field needs now, perhaps more than ever.
The Bottom Line
Soumith Chintala joining Thinking Machines Lab represents a power shift in global AI leadership. For users, developers, and startup enthusiasts, this is a rare moment: an inflection point where the next generation of AI infrastructure could be shaped by those closest to the code, not just the boardroom. The race to attract—and retain—top research minds is not just about prestige. It is about defining the next era of scalable, responsible AI that can be trusted, tested, and advanced at web speed.
