IncludedMoonshot AI released Kimi K3.1 Pro on its API on October 23, with full model weights promised by November 4. Simon Willison reported the model is priced at $2/million input tokens and $10/million output tokens—matching GPT-6.1 Sol and undercutting Claude Opus 5.5. The company also offers a "Highspeed" variant 2–3× faster at double the price, except for cached input tokens.
