alt Hacker NewsYou unknowingly substituted the name of another model when you’re otherwise talking about the competitor fwiw. Some if those in the reply chain didn’t even seem to notice.
That’s a little telling of the state of ai atm though isn’t it? It’s all pretty similar. The latest Opus/GPT/Gemini/Deepseek/Kimi on medium does indeed do the job
It would be a little strange but not that strange for someone to have an idiosyncratic preference for GPT-5.5. It's still available as a Codex model (I think? It's selectable in Pi, not Codex itself), and it might perform differently enough from later GPT models that someone prefers it.
To your point, though, I don't know if I've noticed that big of an impact going from 5.5 to newer GPT models. If I had to switch back, I'm not sure how much I'd miss the newer ones. People talk about e.g. Opus 4.6 similarly, I've noticed.
The bigger change in OpenAI-land IMO is the models got cheaper, generally.
