This is my biggest gripe with these LLMs. I primarily use Claude, and it exhibits the same described behavior. I'll find myself in a flow state and then somewhere around hour 3 it starts to pretend like it isn't capable of completing specific tasks that it had been performing for hours, days, weeks. For instance, I'm working on creating a few LLCs with their requisite social media handles and domain registrations. I _used_ to be able to ask Claude to check all US State LLC registrations, all major TLD domain registrations, and USPTO against particular terms and similar derivations. Then one day it just decided to stop doing this. And it tells me it can't search the web or whatever. Which is bullshit because I was verifying all of this data and ensuring it wasn't hallucinating - which it never was.
