Can't change LLM model in assistant panel

[TeijiW]

Summary

Trying to change models in the assistant panel fails to actually change the model. This occurs even with Anthropic API Key configured, and prevents selecting a model or sending messages to the assistant.

I found several similar issues, but there doesn't seem to be a permission problem or anything like that. However, nothing is being written to my settings file - I'm not sure if this is expected behavior.

Steps to trigger the problem:

1. Configure Anthropic API Key using env var or using the interface of zed
2. Try to change the LLM model

Actual Behavior: The LLM model doesn't change and it's not possible send any message

Expected Behavior: The LLM model changes and then I can send message and use commands.

Hey, thanks for reporting. This is definitely buggy behavior, and I hope to have this fixed for you soon!

[maxdeviant]

This seems to be the same issue as #24738.

Thank you for the report, @TeijiW!

I can't seem to reproduce what you're seeing. Can you share your settings.json file? Also, can you try again with the latest Zed Stable? (v0.174.6) 🙏

[TeijiW]

Hi @as-cii!
Here is my settings.json.
Observations:

• field default_open_ai_model appeared recently (now actually)
• I've inserted "assistant" settings (except for "dock": "left") right now
• Also, the version mandatory field for assistant appeared recently too

Now look it's working! Actually I don't know if I've done something or if is the fix from 0.174.6 version.
I'll not try to change the model, just keep using Claude 3.5 Sonnet haha

I noticed that now I'm not able to sign in, but I think it's another issue.
