Thinking Machines Lab
Overview
The highest-profile AI lab spinout in history, founded by former OpenAI CTO Mira Murati with a founding team of senior OpenAI researchers including John Schulman (RL/alignment research lead) and Barrett Zoph. Murati was named 2026 CNBC Changemaker. Secured the largest seed round ever ($2B at $12B) and a significant Nvidia investment with commitment to 1 GW of Vera Rubin systems.
Current State
- Pre-revenue, own models expected 2026
- Released Tinker fine-tuning API as first product
- Nvidia made "significant investment" (Mar 2026) + 1 GW Vera Rubin commitment
- Reportedly seeking $5B at $50B valuation
Timeline
- 2024-09 — Mira Murati departed OpenAI as CTO
- 2025-01 — Thinking Machines Lab founded
- 2025-07 — Raised $2B seed at $12B valuation — largest seed round ever
- 2026-03 — Nvidia investment + 1 GW Vera Rubin systems commitment
Competitive Position
The founding team is TML's primary asset: Murati's product vision (scaled ChatGPT at OpenAI), Schulman's RL and alignment research (PPO, RLHF), Zoph's scaling research. The team composition suggests a lab that takes alignment seriously by design — Schulman's research focus is alignment methodology, not pure capability.
The Nvidia partnership (compute commitment) provides infrastructure parity with larger labs. The key question: can they ship competitive models before their $2B runs out, or will they need the $50B raise?
