Out of curiosity - can you give any examples of the programming questions you are using deep research on? I’m having a hard time thinking of how it would be helpful and could use the inspiration.
Easy, any research task that will take you 5 minutes to complete it's worth firing off a Deep Research request while you work on something else in parallel.
I use it a lot when documentation is vague or outdated. When Gemini/o3 can't figure something out after 2 tries. When I am working with a service/API/framework/whatever that I am very unfamiliar with and I don't even know what to Google search.
I recently asked Chrome to show me how to apply the Knuth-Bendix completion procedure to propositional logic, and I had already formed my own thoughts about how to proceed (I'm building a rewrite system that does automated reasoning).
The response convinced me that I'm not a total idiot.
I'm not an academic and I'm often wrong about theory so the validation is really useful to me.
That’s a perfect example of LLMs providing epistemic scaffolding — not just giving you answers, but helping you check your footing as you explore unfamiliar territory. Especially valuable when you’re reasoning through something structurally complex like rewrite systems or proof strategies. Sometimes just seeing your internal model reflected back (or gently corrected) is enough to keep you moving.
