Inkling Small available on Baseten

Inkling Small is now available through Baseten Model APIs. Send requests to thinkingmachines/inkling-small through our OpenAI-compatible endpoint with your Baseten API key. Dedicated deployments are also available for larger workloads.

Inkling Small is Thinking Machines Lab’s open-weights, 276B-parameter mixture-of-experts model with 12B active parameters. It retains Inkling’s 1M-token context window, native text, image, and audio inputs, tool calling, structured outputs, and controllable reasoning in a smaller model designed for workloads where latency and inference cost matter. Thinking Machines reports comparable performance to Inkling at roughly one-quarter its size.
