Model Card
Inkling Small is a mixture-of-experts model from Thinking Machines Lab, the AI research company co-founded by former OpenAI CTO Mira Murati. Released on July 30, 2026, about two weeks after the flagship Inkling FP4, it has 276 billion total parameters with 12 billion active per token, roughly a quarter of Inkling FP4's active-parameter count, and its weights are released under an Apache 2.0 license.
Like its larger sibling, the model is multimodal, accepting text, image, and audio inputs and producing text output, and it supports controllable reasoning effort.
Thinking Machines Lab reports 80.2% on SWE-bench Verified, 89.5% on GPQA Diamond, and 82.2% on IFBench. On the third-party Artificial Analysis Intelligence Index it scores 40, within a point of Inkling FP4's 41, and the company says it beats Inkling FP4 on several reasoning and coding benchmarks while trailing it on factual-knowledge evaluations. It is available through Together AI's inference platform.
