   I was able to reproduce this and traced it to the model resolution path.
   From what I can tell, qwen/qwen3.6-plus:free is still present in the built-in model table, but the runtime also treats the free variant as deprecated. That seems to leave paid qwen/qwen3.6-plus in a broken state for selection / resolution.
   I’d be happy to put together a fix for this if that would be helpful. My current plan is to keep the change minimal and focus on the model definition / resolution path only, so it doesn’t affect unrelated providers.
   If someone is already working on a fix, I’m happy to avoid duplicating effort.

   workaround: you can add this config to opencode.json (inside the provider block). i can call with this (go plan). then choose /models again in opencode.

       "custom": {
         "npm": "@ai-sdk/openai-compatible",
         "options": {
           "baseURL": "https://opencode.ai/zen/go/v1",
           "apiKey": "your-key-here"
         },
         "models": {
           "qwen3.6-plus": {
             "name": "qwen3.6-plus"
           }
         }
       }
