How this price is scoped: Tinker Serverless Inference (Beta) list price for the 256K-context nvfp4 sampling endpoint, the only per-token inference rate Thinking Machines publishes. Tinker's separate training/fine-tuning tiers are priced per 1M tokens as well but bill prefill, sample and train legs individually and are not a hosted-inference list price.
Price receipt
We read Thinking Machines's own pricing page on and found Inkling listed with a price on the same row — that read is where the number above comes from. We keep the page text we read; its content hash is 1e34d6686b.
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.
