How Kimi pricing works
Kimi K3.1 Pro costs $2.00 input and $10.00 output per million tokens, and Kimi K3 costs $3.00 and $15.00. The K3 models have a 1,048,576-token context window. The high-speed K3.1 variant costs $4.00 and $20.00. The K2 models (K2.7 Code and K2.6) cost about $0.95 input and $4.00 output and have a 262,144-token context window.
Caching and batch
Context caching is on by default with a 5-minute lifetime. For K3 models, cache writes are billed separately by lifetime (for K3.1 Pro, $2 per million tokens for 5 minutes and $4 for 1 hour), and cached input is billed at the cache-hit price only. Batch inference on K3.1 Pro and K3 is billed at 60% of the standard price.
K2 retirement
Moonshot says K2 models will not be available to newly registered users from October 31, 2026, and plans to retire all K2 models by the end of December 2026.
A worked example
With 1,500 input and 400 output tokens per request and 1,000 requests a day, Kimi K3.1 Pro costs about $210.00 a month, and Kimi K3 about $315.00 a month, with no caching.
