Inkling 2 Small - access through LLMTR
Inkling 2 Small is a second-generation Inkling model from Thinking Machines: a Mixture-of-Experts architecture with 594 billion total and 17 billion active parameters per token, trained for agentic coding and multi-step tool use. It reasons step by step before answering, and you tune that effort with `reasoning_effort` across six levels from none (off) to xhigh. It accepts images as base64 data URLs; it does not accept audio input. It makes tool/function calls and can call several tools in one turn, produces JSON object output, and supports prompt-cache reads. It offers a 256K context window. Reasoning tokens are returned inside `completion_tokens` and billed as output.
