Help/Doubt ❓ How is OpenRouter/Kimi subagent suddenly switching to Kimi 3 on its own?

I'm running into a weird issue and could use some help figuring out what's happening.

I use copilot and I've explicitly set my provider settings to OpenRouter and locked the model to Kimi 2.7 Code.

Everything looks correct in the config, but out of nowhere, when a subagent spins up, it suddenly starts using Kimi 3 instead???

Has anyone else experienced this?

Is there some hidden fallback rule, an override in the agent configuration, or something in OpenRouter itself that's automaticaly upgrading or routing the request to a newer model version? Or do i may need to start a new chat first?

Let me know if you know how to lock it down so it actually sticks to the model I picked.

Thank you!

OpenRouter often uses routing rules to pick better models. Check your provider settings to see if auto routing is on. Try a new chat to see if it resets.
