Inkling - access through LLMTR
Inkling is Thinking Machines' flagship open-weights model: a Mixture-of-Experts architecture with 975 billion total and 41 billion active parameters per token. It reasons step by step before answering, and you can tune that effort per request — six levels from none (off) to xhigh via `reasoning_effort`. It accepts images as base64 data URLs, makes tool/function calls, produces JSON object output, and supports prompt-cache reads. Reasoning tokens are returned inside `completion_tokens` and billed as output.
