Thinking Machines Lab is an artificial intelligence research and product company founded by former OpenAI CTO Mira Murati in February 2025. The company is building a future where everyone has access to the knowledge and tools to make AI work for their unique needs and goals.

The company's mission centers on three pillars: making AI systems more widely understood through open research and publications, developing strong foundations for more capable AI systems at the frontier of science and programming, and building AI that works collaboratively with humans across all modalities. Thinking Machines Lab launched Tinker, a training API for researchers to fine-tune open-source language models, and is developing interaction models that handle real-time human-AI collaboration natively rather than through external scaffolding.
