Thinking Machines Lab Releases Inkling, a 975B Open-Weight Model With Self-Fine-Tuning Capability, Creating New Intake and Agentic Governance Obligations

Thinking Machines Lab has released Inkling, a 975B-parameter open-weight Mixture-of-Experts model pretrained on 45 trillion tokens of multimodal data, with full weights available for public download and fine-tuning. The model supports a 1M-token context window and is paired with a hosted fine-tuning platform called Tinker. A demonstrated self-fine-tuning capability, in which the model wrote and executed its own fine-tuning job autonomously, introduces governance complexity around agentic autonomy and model change provenance.
