kimi-k2-5
Capability: 256K context · tool use · streaming · structured output · CJK-native
Pricing: per-token, mid tier (live rate)
Kimi K2.5 is Moonshot’s prior flagship. Native Chinese / Japanese /
Korean prompt understanding, and the 256K context window made it the
default for long-document extraction in the Chinese market. Still
production-capable; for new work, Kimi K2.6
is the recommended starting point.
