Editor's note
Recorded from the Kimi API quickstart, vision guide, model list, and homepage price card. Thinking stays on. reasoning_effort is low, high, or max; the API documents max as the default. Output can use the full window; the default cap is 131,072 tokens. Vendor eval tables stay off the ledger. Editorial depth still needs a desk pass.
