Do you have problems selecting model with cursor_cli acp?

I've been noticed that after setting any model in the cursor_cli acp adapter it's considering always the same.

In the cursor dashboard I can see it's considering always sonnet-4.6 even when I selected a lot of different models.

When I run agent in the terminal directly (cursor cli) and I set the model via /model it works as expected. When doing it via CodeCompanion acp adapter it doesn't.

I also tried to ask for the model in the codecompanion chat:

Change to opus 4.6
What's the current model?
AI: I'm Sonnet 4.6 from Anthropic.

When using agent (cursor cli) directly:

Change to Opus 4.6
What's the current model?
AI: Claude Opus 4.6 from Anthropic.

It seems to be some acp integration, what do you guys think?

I'm fairly confident this is an issue with how they've implemented the protocol. Session Config Options were added at the start of Feb but I recall there being a number of ACP implementations that didn't implement it. Copilot CLI is still lagging on a few. Definately raise this upstream with them.

As an aside, I tend to use a mixture of the chat buffer and the CLI interaction. So I can have the benefit of using the native CLI tool whilst being able to easily send context from within Neovim.

@olimorris
Do we have this kind of customization?

They suggested this workaround.

Yep but you'll need to overwrite the ACP command on the adapter itself in your config
