Overview
Thinking Machines' first frontier model: a 975B-total / 41B-active Mixture-of-Experts transformer that reasons natively over text, images and audio, with controllable thinking effort. The weights are open on Hugging Face, and the lab also sells it directly through Tinker's serverless inference at $1.00/$4.05 per 1M tokens, with cached input at $0.17.
Deploy this open model on rented GPUs
Open weights mean you can self-host instead of paying per-token API prices. These platforms let you serve it on demand — often cheaper at scale.

Capabilities
struck through = not supportedBenchmark performance
accuracy % · higher is betterWe hold no per-benchmark accuracy scores for this model yet, so it has no accuracy average. That is a gap in our coverage, not a sign the model is untested — independent evaluators often publish a composite index for a new model long before releasing its per-benchmark numbers. The percentile above is its standing across the independent composites below.
- AA Intelligence Index: 40.7 (Artificial Analysis composite across reasoning, knowledge and coding evals)
- AA Agentic Index: 32.3 (Tool use, planning, autonomy)
- AA-Omniscience Index: 2 (−100–100)
- GDPval-AA v2: 1236.8 ELO (Real-world work tasks, human baseline = 1000)
- LMSYS Chatbot Arena: 1440.8 ELO (Human preference)
- Ranks #51 of 136 comparably-measured models by percentile score, across 5 independent measurements
- Ranks #73 of 136 comparably-tested models by normalized performance per dollar
