Flagship

kimi-k3

Reasoning · Speedmoonshot/kimi-k3Moonshot’s 2.8T-parameter flagship MoE with a 1M-token context window, native vision/video, and always-on reasoning for long-horizon coding and knowledge work. Pass reasoning_effort via model_params ("low", "high", or "max"; default "max"). Do not set temperature — the API fixes it at 1.0.
  • $3 / $15 (cache-hit input $0.30)
  • 1M context
  • Text, Image, Video input
  • Thinking (reasoning_content / reasoning_effort)

​
Coding

kimi-k2.7-code

Reasoning · Speedmoonshot/kimi-k2.7-codeCoding-focused multimodal model with always-on thinking for long-context programming agents. Leave sampling parameters at their fixed defaults and use tool_choice="auto" or "none".
  • $0.95 / $4 (cache-hit input $0.19)
  • 256K context
  • Text, Image, Video input
  • Thinking

kimi-k2.7-code-highspeed

Reasoning · Speedmoonshot/kimi-k2.7-code-highspeedSame K2.7 Code weights with higher output throughput (~180 tok/s) for interactive coding.
  • $1.90 / $8 (cache-hit input $0.38)
  • 256K context
  • Text, Image, Video input
  • Thinking

​
General

kimi-k2.6

Usage

​
Cache billing and lifecycle

K3 cache reads cost $0.30 per million tokens. Cache writes cost $3 for the default 5-minute TTL or $6 for 1 hour. Reads, writes, and uncached input are disjoint; do not add a write charge on top of ordinary input for the same tokens. The catalog stores the 5-minute write rate. The current Chat Completions collector does not distinguish write TTLs, so 1-hour writes require separate reconciliation against provider billing. See cache pricing and usage fields. K3 requires a successful account top-up of at least $1. K3 specifications and the model list were checked October 3, 2026. K2.5 and Moonshot V1 were discontinued August 31; the K2 series was discontinued May 25. These are already absent from this provider’s catalog. All listed token and cache prices were verified October 3, 2026 from the pricing page’s embedded model tables, crosschecked against the platform model cards and cache guide. HighSpeed pricing is published in the detailed table only. Prices exclude applicable taxes.
