Modular manifolds represent a geometry-aware optimization approach that treats neural network layers as geometric modules to achieve more stable and consistent optimization across models.

“Founded Thinking Machines Lab, an AI startup, and is ex-CTO of OpenAI; the team raised about $2 billion at a valuation of $12 billion.”

Soumith Chintala, creator of PyTorch and former Meta AI leader, has joined Mira Murati's Thinking Machines Lab startup, which is aggressively recruiting top AI talent and in talks to raise funding at a $50 billion valuation.

“Former OpenAI CTO who founded Thinking Machines Lab, an AI research and product lab focused on human-AI collaboration.”

Eric Zelikman, former xAI researcher, is raising $1 billion at a $4 billion valuation for Humans&, a startup building empathetic AI models that learn from and understand users better than current language models.

“Started Thinking Machines Labs, an AI firm that raised $2 billion in a seed round at a $12 billion valuation.”

Mira Murati's lab identifies that the common 'concurrency + floating point' hypothesis does not fully explain LLM inference nondeterminism, suggesting a deeper underlying cause.

“Her lab found the cause of inconsistent LLM outputs related to nondeterminism in inference.”

AI unicorns are shifting from pure hype to proven commercial maturity in 2025, with both new AI and non-AI startups increasingly reaching $1B+ valuations at the scaling stage rather than earlier development phases.

“Former OpenAI CTO who co-founded Thinking Machines Lab and raised a record-breaking $2B seed round at a $12B valuation in June 2025.”
