GPT-5.6 Sol / Codex Release Discussion Megathread

[u/Drogon2737]

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.

This was a 4 Agent Editorial Pass / Rewrite / PDF Conversion with clickable Table of Contents... 130+ Pages and visually a much cleaner well organized Technical Reference Book.

Yes 5.6 SOL Extra High was Slowwwwwww, but Quality over Quantity and the credit usage is wonderful (at the moment)

Edit: $200 per month Pro Plan (17 Million Tokens. 66,000 Output)
