Pricing Details
Moonshot2.8T param MoE (16 of 896 experts active), native vision, always reasons. Cached input: $0.30/1M. Full 1M context billed flat with no length tiering. Max output defaults to 131,072 and can be raised to the full 1,048,576. Rate card is 3.16x input and 3.75x output over K2.6. AA Intelligence Index 57, rank #4 (Jul 17, 2026), at $0.94/task vs Opus 4.8's $1.80; #1 on Arena Frontend Code (1679). Very verbose: 130M tokens across AA's suite vs 63M average, though ~21% fewer output tokens than K2.6. AA measured hallucination rising to 51% from K2.6's 39%. Open weights released 2026-07-27 on HF (moonshotai/Kimi-K3), ungated, modified-MIT (separate agreement required for MaaS operators above $20M/12mo revenue). Checkpoint is 1,560.9 GB in MXFP4 across 96 shards; vLLM requires 8x B300 / 16x B200 minimum (8x MI355X also fits), so no host undercuts the first-party rate on synchronous requests: Fireworks, Together, Baseten, SiliconFlow, Novita and Atlas Cloud all match $3.00/$15.00/$0.30. Nebius matches $3/$15 with no cache discount ($4.20 blended). Only sub-list price anywhere is Fireworks batch at $1.50/$7.50 (platform-wide 50% async modifier). Note K3's license adds a MaaS clause K2's lacked. API ID: kimi-k3.

Anthropic counted 189.9 million distillation exchanges across five Chinese labs and printed no token count and no dollar figure. At the Opus card the campaign is worth between $5.7M and $40M, and every Kimi request Moonshot relayed to Opus would have lost 40 cents on the dollar if anyone had paid for it.
