What they're building
Mira Murati's frontier lab has one of the densest concentrations of former OpenAI talent anywhere. Its first product, Tinker, lets researchers fine-tune open-weight models with full control of the training loop; a frontier model of its own is in development.
Latest developments
- Tinker fine-tuning API opened to wider access in 2026.
- Continued hiring from OpenAI, Meta and Google DeepMind.
- Reported in talks for additional funding at a sharply higher valuation.
Why it matters
Talent density is the leading indicator in this race, and Thinking Machines has it. The question is whether it ships a frontier model before the giants pull away.
