Thinking Machines has announced Inkling, an open-weights foundation model trained from scratch and released with full weights.
- Architecture: a Mixture-of-Experts transformer with 975B total parameters and 41B active.
- Context window: up to 1M tokens.
- Training data: 45T tokens across text, images, audio, and video.
- Product strategy: Inkling is positioned as a customizable base model rather than the strongest model overall, and is available for fine-tuning on Tinker.
- Family roadmap: the company also previewed Inkling-Small, a 12B-active variant aimed at lower cost and latency.
The release emphasizes multimodal native reasoning, efficient/controllable thinking effort, and a broader push to make customization easier through the Inkling Playground in Tinker.
