Calling MiniMax M3 on KeepRouter

Point a compatible client at the supported KeepRouter endpoint and set the model to MiniMax-M3. KeepRouter preserves the client-facing request shape while handling upstream routing or translation. Use POST /v1/chat/completions or, on compatible chat routes, POST /v1/messages; streaming and tool support depend on the model's active route.
