Nvidia-backed Thinking Machines Lab has unveiled a new open-weights model that performs “comparabl[y]” to Inkling, but at one-quarter its size.

An open-weights model that matches Inkling at a quarter of the size: multimodal, Mixture-of-Experts, with controllable reasoning effort. Fine-tune it on Tinker.

For companies that want control over data, model behavior and fine-tuning, that smaller footprint may be more important than chasing the highest possible benchmark score.
