Ah yeah jagged intelligence is the perfect phrase for it. I do also get some value from them, both in coding and in images. I find it the least usable for information primarily because of the hallucination problem. I still do use it for that purpose but it's kind of annoying when it writes something that's wrong, and I find it out from a Google search later.
You are cooking them wrong. You absolutely must ask the model to do grounding work — search online, search in your files, cross-check with different agents. They are universal reasoning engines, not a fact recalling tool.
Check my 'deep research' skill, you will get the idea
