Summary

Issue: Playground runs with long-running models like gpt-5-mini (85+ seconds) appear to hang or timeout, showing no progress updates in the UI even though the request completes successfully in the background. Cause: Server-Side Events (SSE) connection drops before the job completes, preventing the UI from receiving completion updates. Resolution: Refresh the page to view completed results

​
Resolution Steps

​
Workaround for current issue

​
Step 1: Wait for expected completion time

Allow sufficient time for the model to complete processing (typically 85+ seconds for gpt-5-mini).

​
Step 2: Refresh the browser page

Reload the page to display the completed results that processed in the background.
