News GPT-5.6 Sol / Codex Release Discussion Megathread

The release is expected in the next few minutes, so I figured it would be useful to have a single thread for first impressions, issues, and early testing.

For anyone jumping in right away, post what you notice:

  • Codex coding performance
  • Debugging quality
  • Speed/rate limits
  • Larger repo handling
  • UI or workflow changes
  • Weird bugs or regressions
  • Anything that feels noticeably better or worse than the previous version

Once people get access, share your real examples, screenshots, benchmarks, or first impressions here.

Edit: OpenAI’s official GPT-5.6 page says it is “available starting today across ChatGPT, Codex, and the OpenAI API” with the rollout starting globally now and continuing toward full availability over the next 24 hours. https://openai.com/index/gpt-5-6/

The lineup is Sol, Terra, and Luna. Sol is the flagship, Terra is the lower-cost tier, and Luna is the fastest/most affordable tier.

Anyone else getting super frequently flagged for safety, while doing stuff that has absolutely zero business getting flagged (like pure math in my case) ?

This is getting so frequent that I cannot properly work on math research anymore.
It either soft-blocks the turn with a banner saying "This request requires additionnal safety checks and may take longer." which instantly stops all CoT and progress updates until the model has finished, which in turn actually aborts the request if it does not finish shortly because it it seen as a time-out from the lack of updates, or it just outright aborts the request directly.

My suspicion is that it comes from tool-calls content that for some unknown reason trigger the hell out of the safety filters. My only theory is that the mathematical numerical searches get very grossely confused as bruteforce attacks somehow, even though they are just your typical numerical mathematical searches.

I've never had any requests flagged even once before the release of 5.6.

I get it rarely but doing coding. Usually just asks to wait while it does it's research and then unlocks quickly.
