Brief

Thinking Machines introduced Inkling on 2026-07-15: an Apache 2.0 open-weights multimodal Mixture-of-Experts model capable of reasoning across text, image, and audio with controllable reasoning effort. The team released full weights, supports fine-tuning on Tinker, and provides an Inkling Playground; @itsandrewgao claims this could be the leading American open-source model given the company's talent and infrastructure.
