agentic rag basically works now, so why trust a proprietary "research" api over just running your own agent?
maybe i'm missing something here, genuinely asking.
these days agentic rag kind of just works? you give an agent a search tool and a fetch tool, write a decent prompt, let it loop — search, read, reflect, search again, synthesize — and you get solid grounded answers out the other end. you own the loop, the prompt, the model, the reranking, all of it.
so every time i look at one of these "research for agents" products — exa, parallel, tavily's research thing, that whole category — i end up at the same thought: under the hood they're doing the exact same thing i'd do, running an agent loop
internally, just with a few extra controls bolted on top. and the underlying data is the same internet for all of us anyway.
is that delta — "a few extra guardrails" — actually worth handing your whole retrieval layer to a black box you can't see into or tune for your own domain?
the only part i genuinely can't replicate in an afternoon is the data side: a real index over the open web, not getting blocked at scale, clean extraction that doesn't dump nav/footer junk into my context. everything above that i'd rather just own.
so i'm honestly curious what people actually think. if agentic rag is this accessible now, what's left that makes a proprietary research api worth trusting or paying for? real value, or mostly convenience?
