@shaytan_9 @pshemyslaw I prompt "make a doom-style game using webgl" whenever a new model drops and it's really interesting to see what they produce. 5.5 was quite different compared to other models (fancy 3d, shadows etc).

GPT-5.5 may not be in the official OpenAI API... but it's available via the apparently approved-of Codex API backdoor
So I used that to make these pelicans (default and xhigh)! simonwillison.net/2026/Apr/23/gp…

@bygregorr We want people to be able to use Codex, and their ChatGPT subscription, wherever they like! That means in the app, in the terminal, but also in JetBrains, Xcode, OpenCode, Pi, and now Claude Code. That’s why Codex CLI and Codex app server are open source too! 🙂

Spotlight-style floating terminal powered by libghostty. Hit a hotkey, terminal drops down. Hit it again, gone. Prewarms the next shell session in the background while the panel is hidden. Thanks @mitchellh for making libghostty awesome. github.com/drdator/ghostl…

Opus 4.6 is a really good model, but I'm not sure if I love the direction...

i cannot believe how much better 5.3 is than 4.6.
after some internal testing results show its 15.2% better

GPT-5.3-Codex and Opus 4.6 both just dropped within a few minutes of each other
