The Company

Thinking Machines Lab was founded in 2025 by Mira Murati and a group of former OpenAI researchers and leaders. Its stated ambition is to build multimodal AI that works naturally with people and supports collaborative use, rather than focusing solely on a single consumer assistant.

The company closed a reported $2 billion seed round in July 2025 at a $12 billion valuation. In 2026 it released Inkling, an open-weight model positioned around customization, giving outside observers an early product signal after its initial research-focused period.

Why It Matters

Thinking Machines Lab shows how investors are valuing founder quality, research talent, and AI optionality before a mature commercial business exists. Its progress is relevant to the competitive structure of frontier models, open-weight distribution, and the economics of building a new AI lab.
