Description

What issue are you seeing?

Package: Pro 20x
Platform: ChatGPT desktop client for macOS, Codex mode
MacOS version: 26.6.2
Application release: 26.901.51231 (from application logs)

Symptom:
Terra, Luna, Sol, and Astra all continue to prompt:
Selected model is at capacity. Please try a different model.

Confirmed:

  1. Switching models is invalid.
  2. Creating a new session also failed.
  3. The usage page shows that there is still about 80% remaining.
  4. In the main session log, four consecutive task_completes are clearly recorded:
    codex_error_info = server_overloaded
  5. The snapshot of the same period limit shows:
    plan_type = pro
    primary.used_percent = 20.0
    rate_limit_reached_type = null

Research direction

Start with the main session log entries showing codex_error_info = server_overloaded and compare them with the period-limit snapshot showing 20% usage and no rate-limit type. Determine whether the desktop client has an actionable discrepancy to reproduce; done means identifying a client-side cause or confirming that the failure is external server capacity.
