I use Kagi, they provide access to all the main models in a chat interface and have a mode that feeds search engine results to them. It’s mostly replaced search engines for me. For programming work I find them very useful for using unfamiliar tools and libraries, I can ask it what I want to so and it’ll generally tell me how correctly. Importantly, the search engine mode has citations. $25 a month, but worth it.
Have you tried recent models? They’re not perfect no, but they can usually get you most of the way there if not all the way. If you know how to structure the problem and prompt, granted.
