Inkling

Thinking Machines Lab's first from-scratch open-weights family (July 2026): a 975B/41B-active multimodal MoE with 1M context, continuous thinking-effort dial (0.2–0.99), encoder-free audio/vision, and calibration trained via RL on proper scoring rules — positioned not as the strongest open model but as the best base for fine-tuning on Tinker; Inkling-Small (276B/12B) previews the same recipe at interaction-model shape
