| Pricing conditions | Kimi API · launch-post CNY ratesThe launch post prices the Highspeed variant at twice the standard K3.1 Pro rates — about ¥2.6 cache-hit input, ¥26 cache-miss input and ¥136 output per million tokens — without showing a separate listing.Moonshot AI · Kimi K3.1 Pro launch post ↗ |
| Output speed · tokens/s | Not benchmarkedMoonshot states roughly two to three times the standard model's output speed. No absolute tokens-per-second figure was published, so no verified speed classification exists. |

Language prices are USD per million tokens; input and output are billed separately. Video samples use 5s of 768P output where verified. Extra tools, reasoning, cache writes, input media, storage, and taxes can change the total. (fast) marks a published median output speed above 150 tokens/s in the linked test settings.
