Kimi sets separate standard and Highspeed API rates for K3.1 Pro

Moonshot AI lists Kimi K3.1 Pro API standard rates at $2 per million regular input tokens and $10 per million output tokens, with $0.20 cached input. Highspeed costs $4 input and $20 output; cache-write charges also vary by duration. API use is billed separately from Kimi memberships, so a subscription does not include these tokens.
