Ngl after opus 4.5 I haven’t noticed too many improvements

I still oscillate between "I'm totally cooked, I have no role here, the AI does everything" to "WTF why is this LLM so stupid today, WTF is it doing? This is garbage?"

A lot of that is because in the former case (AI does everything) I wasn't paying enough attention.

Not intelligence improvement, but the improvements to speed are tangible. In my case I've gotten so used to the speed of Composer 2.5 that using the latest Anthropic models frustrates me. They are so slow, and not really worth the wait times since Composer gets me what I need precisely, much faster. I think you'll see labs care a lot more about latency and tokens per second moving forward.
