Mira Murati’s lab building open-weight multimodal base models and the Tinker customization platform—betting enterprises want models they can fine-tune, not only rent.

Thinking Machines Lab, founded by former OpenAI CTO Mira Murati, trains open-weight foundation models (Inkling family) and operates Tinker, a platform for fine-tuning and deploying customized checkpoints across inference partners.
