I was using Claude 3.7 exclusively for coding, but it sure seems like it got worse suddenly about 2–3 weeks back. It went from writing pretty solid code I had to make only minor changes to, to being completely off its rails, altering files unrelated to my prompt, undoing fixes from the same conversation, reinventing db access and ignoring existing coding 'standards' established in the existing codebase. Became so untrustworthy I finally gave OpenAi O3 a try and honestly, I was pretty surprised how solid it has been. I've been using o3 since, and I find it generally does exactly what I ask, esp if you have a well established project with plenty of code for it to reference.

Just wondering if Claude 3.7 has seemed differently lately for anyone else? Was my go to for several months, and I'm no fan of OpenAI, but o3 has been rock solid.

Could be the prompt and/or tool descriptions in whatever tool you are using Claude in that degraded. Have definitely noticed variance across Cursor, Claude Code, etc even with the exact same models.

Prompts + tools matter.

Cursor became awful over the last few weeks so it's likely them, no idea what they did to their prompt but its just been incredibly poor at most tasks regardless of which model you pick.

Me too. (re: Claude; I haven’t switched models.) It sucks because I was happily paying >$1k/mo in usage charges and then it all went south.
