Model selection

[mderazon]

Just tried Gemini CLI + ACP in Zed.
Super cool!

But there's no way to see, let alone manage, which model is currently used.
I asked in the chat, "Which model are you?" and it responded Gemini 1.5 Pro (and said it is the latest model)

The lack of visibility is problematic, especially since Gemini tends to rate limit and switch to Gemini Flash frequently.
Also would be awesome to have some sort of visibility over the quota that has been used

Thanks for the feedback @mderazon
Adding model selection to the protocol is one of our near-term items, and we definitely want to help make this visible for all agents that support it. Especially knowing when you are in the default/auto mode where fallbacks are possible.

Yes please this would be super helpful

Bumping this - we'd love to make ACP work with Droids, but we've noticed supporting models isn't first class. @benbrandt

Hi, we have unstable support in the protocol/sdks, but I don't see the schema needing to change. It's on my todo list to stabiliize (meaning document) it this week, but feel free to give it a try and give feedback if it doesn't work for you.

We have it supported in Zed and both the claude code and codex adapters are using it if you want to take a look for reference.

Bumping this again :) I'v seen that instead of stabilizing the unstable schema https://agentclientprotocol.com/rfds/session-config-options was born. How it is going?

Need this!

any update on this, this is one of the major blocks in using various providers as we don't know which model is being used and we cannot switch models as well. Another major thing is context and pricing. @benbrandt anything on this?

Hey everyone the Session Config Options is in preview and will likely be stabilized in the next week!

[bhupesh-sf]

oh, thank you very much. This will be so cool, will look for the update.

[bhupesh-sf]

any update on session config here?

[benbrandt]

It is stabilized! and several agents and clients are already supportingit

[bhupesh-sf]

oh I thought just RFD has been finalized, wasn't aware if code also merged. If I update the package will I get this functionality there?

[benbrandt]

you hopefully should! Which package/sdk are you using?
