Thinking Machines: Inkling Small

Inkling Small is a Thinking Machines model that accepts text, image, and audio input. It offers a 524,288-token context window and can return up to 262,144 tokens in a single completion, enough room for long documents, large codebases, or extended transcripts. It supports tool calling and reasoning. The available data does not confirm structured output support or whether the weights are open. Pricing is $0.45 per million input tokens and $1.20 per million output tokens. Teams handling high volumes of long or mixed-media inputs should weigh it against similarly priced options. Its blended benchmark score of 40.6 rests on a single independent benchmark, an AI Index score of 42.3. That is too little evidence to place it reliably against alternatives. Treat it as a candidate to test on your own workload rather than a proven performer.
