Desktop app completely unresponsive - all free models fail to generate responses #47252

Bug Description
The opencode desktop application is completely non-functional. When I send any message, the AI never responds. The message appears in the chat but no response is ever generated. This persists across all free models and multiple reinstall attempts.

Expected Behavior
The AI model should process the input and generate a response within a reasonable timeframe.
Actual Behavior

• Message is sent and appears in the chat interface
• No response is ever generated
• The response area remains completely blank
• No error message is displayed
• The app appears to be stuck/waiting indefinitely
• This happens with every free model I've tried
  Models Tested (all failed)
• Muse Spark 1.2 Free
• Muse Spark 1.3 Free
• Big Pickle Free
• MiMo V2.5 Free

Environment

• Operating System: Windows 11
• Installation Method: Downloaded from opencode.ai

Troubleshooting Attempted

• Reinstalled the application completely (uninstalled, downloaded fresh, reinstalled)
• Tried multiple different free models
• Started new sessions/conversations
• Restarted the application
• Verified internet connection is working

Additional Context

• The CLI version works perfectly. I am currently using opencode in my terminal and it functions correctly with no issues. This confirms the opencode service itself is operational.
• The desktop app connects and loads the UI fine, but the actual AI inference/completion never happens
• No error messages are shown - it just silently fails to respond
• The app shows the model name and "Default" in the bottom bar, suggesting it recognizes the selected model
• I can see the timestamp on my sent messages but no response timestamp ever appears
