opus 4.8 has been making weird mistakes that confuse me in conversation, stuff like minorly misreading my intent or getting confused about which of us said what in previous conversations. mistakes i haven’t seen gpt-5.5 make yet. but it also often responds to my questions with analysis that suggests a kind of philosophical depth that seems more serious than gpt’s or something. not sure what to make of either of these
