In my experience, 4.7 was a noticeable step down from 4.6.

I was one of these people that Claude would never finish anything and just randomly say, this is a good stopping point, I think you should go to bed.

And then I'd tell it to continue, and it would burn tons of tokens, make no progress and say, "This is a really good stopping point..."

Canceled and switched to Codex and have been pretty happy with it. It doesn't plan as well as Claude, but I think it does better implementation - and neither of them can actually come up with good plans without a ton of help...

Codex is also way faster.
