I really want to like Gemini Deep Research but I have had a pretty low ROI with it. It fails because it has no ability to evaluate the quality of sources, so some SEOd to hell page has equal weight as the deep dive blog post of a highly invested individual. Its also very hard to steer unless you provide paragraphs of context, if you provide too little it might hyper focus on something you said and go into some random rabbit hole of research.
