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.
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.
