What issue are you seeing?

Currently, I have been using Codex for 122 consecutive days, consuming a total of 47.36 billion tokens. Due to these points, I have noticed a significant performance decline in gpt-5.5. In the past two days, when using gpt-5.4 high, I occasionally encounter the prompt "Selected model is at capacity. Please try a different model." I am currently a Pro user with sufficient credits.

@gaoyangz77 你是把 pro 接在中转上吗,还是直接用 codex?

I am seeing the same Codex capacity error today.

Error shown:

Selected model is at capacity. Please try a different model.

Context:

  • Surface: Codex chat/app experience
  • Approx observed time: 2026-06-25 around 11:56 AM IST
  • Behavior: after sending a follow-up message, the thread showed the capacity error and remained in a Thinking state.
  • Retrying did not immediately resolve it.

I also raised this privately through OpenAI Help Center. Support confirmed there is an active Codex incident today, but the public incident text is for access-token issues, so it is unclear whether this exact capacity error is the same root cause or a separate recurring capacity/admission issue.

Related status pages:

Expected behavior: Codex should either route to an available model, retry gracefully, or show a clear message explaining whether this is model capacity, quota, account access, or incident-related.

Sachin619619 · 25 days ago

Adding a follow-up: this is not a one-off occurrence. The same error is repeatedly appearing during normal Codex usage:

Selected model is at capacity. Please try a different model.

Impact:

  • The active thread becomes blocked while Codex remains in a Thinking state.
  • Retrying does not consistently recover the session.
  • The message does not make it clear whether the cause is model capacity, account access, quota/rate limiting, or the current Codex incident.

Given that the current OpenAI status incident is listed as an access-token issue, it would help if Codex surfaced a more specific error category here. If this is capacity/admission control rather than auth, please track it separately or update the public status/issue guidance so users know whether to switch models, wait, re-authenticate, or retry later.

This problem keeps happening, I can't use it at all.

Sachin619619 · 25 days ago

At this point I cannot use Codex reliably at all because this capacity error keeps blocking active sessions.

anyone is working on it??
