Another annoyance (for more API use) is summarized/hidden reasoning traces. It makes prompt debugging and optimization much harder, since you literally don't have much visibility into the real thinking process.
Opus 4.5 was released on Nov 24 last year. It’s only been 5 months!

Wow you're right, okay not so bad then.
That brief two week period when Opus could eat entire tickets was simultaneously fantastic and a bit alarming
Since then it's just been a cycle of the old model being progressively lobotomised and a "new" one coming out that if you're lucky might be as good as the OG Opus 4.5 for a couple of weeks.
Subjective but as far as I can tell no progress in almost a year, which is a lifetime in 2022-25 LLM timelines
