• Price: 20% below Moonshot's international list price ($3.00 input / $15.00 output per 1M tokens, as listed on platform.kimi.ai on 2026-10-20). See the model catalog for our live price.
• Context: 1M tokens.
• Endpoints: OpenAI-compatible Chat Completions and the Anthropic Messages API, so it can also be used from Claude Code.
