I'm going to cancel Claude. It's just so bad, I can't believe it.

It's just lazy. The most recent example: I have Claude check my inbox for important emails, summarize them, work with them, and send out replies if necessary. I caught Claude again simply not reading the email thread to the end and just ignoring the latest emails.

When I asked him about it, Opus 5 just said: "Valid point. I didn't read it."

I mean, seriously. What the heck? You have to babysit it every time.<br>span:not(:empty)~span:not(:empty)]:before:content-['·'] [&>span:not(:empty)~span:not(:empty)]:before:px-1 [&>span:not(:empty)~span:not(:empty)]:before:shrink-0">7:45 PM · Aug 4, 20261.3MViews

I mean, this is just a trivial example. But it occurs so frequently in different use cases. Claude gets lost in trivialities, pursues strange goals, derails. You have to double-check everything. I honestly just dont get it.

its just so sad to see how to witness the decline of Opus. 4.6 was GOAT, after that it was all downhill.
