Saying it isn't useful is a bit of an overstatement. It can search, churn through 500k words in a few minutes, and come back with summaries, answers, and sources for each point. Should you blindly trust the summary? No. Should you verify key claims by clicking through to the source? Yes. Is it still incredibly useful as a search tool and productivity booster? Absolutely.
If I knew what’s in the paper I don’t need the summary but if I don’t know what’s in the paper I cannot possibly judge the accuracy of its summary.
1. Get list of sources and their summaries from an LLM.
2. Read through, find a paper who's title and summary seem interesting to you.
3. Follow the LLM's link, usually to an arXiv posting.
4. Read the title and abstract on arXiv. You can now judge the accuracy of the LLM's summary.
It's really easy to tell if the LLM is accurate when it is linking to something which has its own title and summary, which is almost always the case in literature search.
