   Thanks for the report, I can reproduce this.

   I put {"providers":{"opencode-go":{"settings":{"baseURL":"http://127.0.0.1:18931/v1"}}}} in ~/.config/opencode/opencode.jsonc, set a dummy key in OPENCODE_API_KEY, and ran opencode run --model opencode-go/<model> hi with a local server logging every request. opencode debug config showed the setting was loaded. Still, every run failed with Upstream request failed: Invalid credential from opencode.ai, and the local server got no requests. I tried deepseek-v4.1-flash, minimax-m3 and gpt-5.6-luna on 2.0.31, and it happens the same way on the latest dev (83c5abbbe).

   It also happens on 2.0.25. The likely reason (not yet confirmed) is a change in the model catalog OpenCode downloads, not in OpenCode itself. The catalog now gives each Go model its own endpoint, and that overrides the provider-level baseURL from your config. That would explain why it used to work.

   The script below reproduces it. Note that it writes to your global opencode.jsonc and saves any existing one as opencode.jsonc.bak.

   Related (not the same problem): #54370, #55984, #54833.
