Zed OpenCode ACP thinking variants cannot be accessible

[validatedev]

Description

I connected my ChatGPT subscription to OpenCode and tried using the official Zed ACP plugin. I can switch thinking variants from the OpenCode CLI, but not from ACP. I’m not sure whether this is a bug or just an unimplemented feature.

Plugins

None

OpenCode version

1.1.23

Steps to reproduce

1. Authenticate ChatGPT via OpenCode.
2. Confirm that authentication succeeded.
3. In Zed, install the OpenCode Agent Server Extension (ACP).
4. Start a new Zed thread using OpenCode.
5. Choose one of the GPT models via the OpenAI provider.
6. Notice there is no option to change the thinking level.
