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 I use it a lot when documentation is vague or outdated.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.
