> Do you actually use these things?
I use them every day for SWE. I cannot remember any hallucination from the last 6 months. It pretty much stopped being an issue from the beginning of this year, if you use top paid models. Free models or lower-tier paid models can still hallucinate, though.
I can use Claude as much as I want at work, and I get hallucinations every day. I'm not even doing anything all that fancy with it, but I get frequent hallucinatory behavior regardless of the model or how I go about things.
Every single time I have asked Claude or another "top tier" offering a detailed question about something I'm an expert in, there's something wrong in the answer. Usually many things.
Do you actually look at what comes out?

I would suggest that your ability to discern when the model is wrong might be the thing that has changed.
