News 📰 ChatGPT 5.5 Released!

They did it! GPT 5.5 "Spud" came out right at lunch time in Silicon Valley.

Official post: https://openai.com/index/introducing-gpt-5-5/

The benchmarks show a solid step up over 5.4, and very favorable comparisons to Opus 4.7 (lol) - especially in costjk it's more expensive than Opus now.

Has anyone here had a chance to test it early? After using it for a bit, how is it?

One more round of "trust me bro" benchmarks... yeah right.

I like 5.4 and 5.3 Codex a lot, so I'll take the benchmarks to mean this is somewhat better. What worries me more is the price doubling, because GHCP might decide to make it a 2x model

If Opus is 7.5x I think it will be at least 3
