I'm sure that GPT 5.5 by vibes will be an excellent model, just like its predecessor was. And hey, OpenAI's pace of progress is excellent if we think about the fact that the previous one came out a month and a half ago! BUT FOR GOODNESS' SAKE OPENAI STOP WITH THE OVER-THE-TOP
INNOVATION

A great model needs a great space to work. Codex gives GPT-5.5 the context, tools, artifacts, browser, and review loop to turn reasoning into work you can ship. https://t.co/9sAnYFBDdlCodex + GPT-5.5 is an incredible combo.
