Soumith Chintala, one of the principal architects of PyTorch, has joined Mira Murati’s new startup Thinking Machines Lab, marking a high-profile hire amid a major reshuffle of Meta’s AI organization. Chintala — who spent 11 years at Meta and nearly eight leading PyTorch’s development — updated his profiles this week to show the move. His arrival lends deep credibility in ML infrastructure to a company already assembling talent from OpenAI, Anthropic and academia, and comes as Meta reorganizes its AI efforts into a new Superintelligence Labs division. Technically, Chintala’s experience with PyTorch signals Thinking Machines’ intent to build or influence core tooling used for model development and deployment. The startup’s early product, Tinker, focuses on making LLM fine-tuning more accessible and is already in use at Princeton and Stanford; adding PyTorch expertise could accelerate low-level performance, interoperability and developer workflows. Thinking Machines is aggressively scaling — offering top-tier compensation, raised a reported $2B seed at a $10B valuation, and is pursuing further funding — intensifying the talent and infrastructure race between big tech, AI labs and insurgent startups.
