Inkling

First open-weights frontier model from Mira Murati's Thinking Machines Lab: a multimodal Mixture-of-Experts LLM (975B total / 41B active, up to 1M-token context) trained on 45T multimodal tokens across text, image, and audio, with controllable thinking effort, uncertainty calibration, and agentic coding/tool use. Weights on Hugging Face, fine-tuning via Tinker.
