Thinking Machines Lab, founded by former OpenAI Chief Technology Officer Mira Murati, has achieved a record-breaking $2 billion seed funding round at a $12 billion valuation – marking one of Silicon Valley's largest early-stage financings. Despite having no product launched, the stealth-mode AI startup attracted heavyweight backers including chipmakers Nvidia and AMD, venture firm Accel, and quant trading powerhouse Jane Street, with Andreessen Horowitz leading the round.

Murati confirmed the company will unveil its first product within months, featuring open-source components to help researchers and startups build customized AI models. "We're creating multimodal AI that interacts with the world through human-like dialogue, visual understanding, and collaborative complexity," she stated. The startup has already recruited talent from OpenAI, Google, Meta, and French AI rival Mistral, with Murati posting job listings alongside the funding announcement to accelerate hiring.

The 36-year-old founder brings exceptional credentials, having co-developed ChatGPT and DALL-E during her OpenAI tenure, where she briefly served as interim CEO during Sam Altman's November 2023 ouster. After leaving OpenAI last September to pursue independent exploration, Murati now leverages her prior experience as a Tesla senior product manager on the Model X development.

Investor participation signals robust industry confidence: Nvidia and AMD's involvement highlights strategic alignment with AI hardware infrastructure needs, while Jane Street continues its focused investments in AI and decentralized finance following its Anthropic backing and FTX asset acquisitions. Andreessen Horowitz's leadership reinforces the firm's established role as a premier tech venture catalyst.
