ex-OpenAI CTO’s startup Thinking Machines Lab raises $2 billion at $10 billion valuation

Thinking Machines Lab, the AI startup founded by OpenAI’s former CTO Mira Murati, has raised $2 billion at a valuation of $10 billion, according to a report by Financial Times. The seed round was led by Andreessen Horowitz with participation from Sarah Guo’s Conviction Partners. 

This could be the biggest seed round in history given the concentration of AI talent. 

The research lab hasn’t announced a product as yet in the six months since it was announced.

“Knowledge of how these systems are trained is concentrated within the top research labs, limiting both the public discourse on AI and people’s abilities to use AI effectively. And, despite their potential, these systems remain difficult for people to customize to their specific needs and values. To bridge the gaps, we’re building Thinking Machines Lab to make AI systems more widely understood, customizable and generally capable,” the website says. 

Ms. Murati quit OpenAI in September over concerns with CEO Sam Altman. Following her exit, a string of AI researchers, including OpenAI co-founder John Schulman, also left OpenAI to join her.
