Thinking Machines Lab Secures Funding

Mira Murati's AI startup, Thinking Machines Lab, has secured $2 billion in funding, valuing the company at $12 billion. This substantial seed round, one of the largest ever, saw participation from Nvidia and Jane Street. The investment will support the development of general-purpose reasoning systems.

Founded in February 2025, Thinking Machines Lab aims to create AI systems that are more widely understood and customisable. The company has attracted talent from leading AI organisations, including OpenAI, Meta, and Mistral. Proceeds from the funding will be used to expand compute capabilities, recruit talent, and secure facilities.

The company is focused on building a next-generation AI platform to enable more collaborative human-AI interaction. Thinking Machines Lab intends to regularly publish technical blog posts, papers, and code for public benefit, to elucidate how these advanced AI systems are trained.
