Moonshot's list price is $3.00 input, $15.00 output, $0.30 cached. ainetcafe rows are our published prices; committed and core plans require a written agreement. OpenRouter rows are as reported by OpenRouter and may lag their own price changes by a day.

How to read it

Cached input matters more than list input for agents: a Claude Code or Cline session resends the same context every turn, and most of it hits the cache.
Quantization: K3's native precision is MXFP4. Providers listed as fp8 or fp4 may be running requantized weights; ainetcafe runs the released MXFP4 weights unchanged.
Uptime here is OpenRouter's 30-minute window for that provider. Our own probe history is on the status page.
