simonguozirui · x · 2026-07-31

Inkling-Small has been officially released, featuring 276B total parameters with only 12B active.

At a quarter of the size of the larger Inkling model, it achieves comparable or superior performance on many benchmarks. It is particularly strong in agentic tasks and reasoning, outperforming strong peers in its class like DeepSeek V4 Flash.

The full weights are now available. Users can fine-tune the model on Tinker or interact with it via text, image, and audio on the Tinker Playground. It is also compact enough to run efficiently on a single DGX Spark.
