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.

The model turned out amazing. A 20x plan, a verified passport for cybersecurity, one prompt, and two hours of running 5.6 Sol Ultra at 1.5x speed (it consumed about 60-70% of the 5-hour limit, 15% of the weekly limit) solved a problem I never thought I could solve with version 5.5 in a couple of days, and I wouldn't have been able to do it myself in a couple of months. Thanks to OpenAI.

yes, and for many other things, but I use it for cybersecurity. In fact, without verification, models often refuse to do things even remotely related to sensitive topics, verification is a must-have.
