What variant of Codex are you using?

Macos app

What feature would you like to see?

Desktop does not render reasoning summaries even though summary events reach the visible renderer.

10723 closed with "Desktop supports live and retained reasoning summaries" but I cannot see it.

Environment

  • macOS
  • Codex Desktop 26.730.61639
  • Build 6234
  • Model: gpt-5.6-sol
  • Reasoning effort: ultra
  • model_reasoning_summary = "detailed"
  • model_verbosity = "high"

What I see

During a task, the conversation shows assistant messages and collapsed tool activity such as “Read files” or “Ran commands.” It does not show any live reasoning summaries, and there are no retained summaries to expand or review afterward.

Diagnostics

The Desktop logs for the affected task show all of the following:

  • concurrent_reasoning_summaries is enabled
  • the turn starts with summary=detailed
  • concurrentReasoningSummariesFeatureOverrideEnabled=true
  • nonempty reasoning-summary parts are received
  • the summary items are completed
  • the primary renderer is visible

The logs include generated summary titles such as:

  • Planning GitHub issue review
  • Verifying installed app version and update status
  • Verifying feature enablement and closure

None of those summaries are visible in the conversation.

This suggests that summary generation and event delivery are working, but the Desktop renderer is not displaying the events.

Update after moving to Codex Desktop 26.803.61601 (build 6396):

  • The original pure renderer failure is no longer reproducible in the same form: title-only reasoning-summary events now appear in the transcript.
  • The remaining problem is upstream of that rendering layer. Raw persisted completed reasoning items contain only a bold heading, or an empty readable summary alongside encrypted content, even though thread_settings_applied confirms reasoning_summary: "detailed" for gpt-5.6-sol.
  • A strict config load succeeds, and explicitly disabling concurrent reasoning-summary delivery in a bounded ephemeral comparison did not restore readable prose.

So the current app appears to render the summary text it receives, but the ChatGPT/Codex route is not supplying the requested detailed prose. The heading-only raw-payload regression is tracked more directly in #34873. I am leaving this issue open as the Desktop/rendering-side record unless maintainers prefer to close it as overlapping with that issue.
