Thinking Machines Lab Raises $2B in Funding Led by Andreessen Horowitz and Nvidia.

Mira Murati, former CTO and interim CEO of OpenAI, has raised $2B for her new AI startup, Thinking Machines Lab. Andreessen Horowitz led the funding round, with Nvidia and AMD participating.

Mira Murati, the former CTO and interim CEO of OpenAI, has raised $2 billion in a seed round for her new AI startup, Thinking Machines Lab. The funding round was led by Andreessen Horowitz (a16z) and included participation from NVIDIA and AMD [1].

Thinking Machines Lab, which aims to advance collaborative general intelligence, secured this significant investment just over a year after its inception. The startup's valuation has increased to $12 billion following the funding round, making it one of the largest seed rounds in Silicon Valley history [1].

The funding will enable Thinking Machines Lab to develop multimodal AI systems that work with natural human interactions through conversation, sight, and collaboration. The company plans to release its first product, which includes a significant open source component, within the next couple of months [1, 3].

Murati, who previously worked with notable figures from OpenAI such as John Schulman and Barret Zoph, has assembled a team with a track record of building successful AI-driven products. The company's mission is to empower humanity through advancing collaborative general intelligence [1, 3].

Thinking Machines Lab faces stiff competition from established AI labs like OpenAI, Anthropic, and Google DeepMind. However, Murati and her team are banking on novel research breakthroughs to differentiate their work. The startup has already struck a deal with Google Cloud to power its AI models [1].
