GPT 5.5 and 5.4 are such great models. I just tried opus 4.8 and took 30 minutes to be confronted with a bit laziness that makes me go crazy. 5.5 just doesn’t have this issue.
How do you compare them to 5.3 Codex? I am using 5.3 Codex for a while, I subjectively think it does better job than Opus 4.6/4.7, with a fraction of the cost, and I did give 5.5 a try and it seems a bit better but magnitudes more expensive.
5.3 is good but talks like a robot, it’s too hard to understand what exactly it’s talking about. When using droid I use it to act like worker model and does a great job.
All 5.x models suffer from weirdness in the way it writes but 5.5 and 5.4 are much better and now offer a good balance, direct but without being like Claude.
