alt Hacker News>I argue that, had they not run to an LLM, they likely would have solved this problem more efficiently
Hard disagree. Asking an LLM is 1000% more efficient than reading docs, lots of which are poorly written and thus dense and time-consuming to wade through.
The problem is hallucinations. It's incredibly frustrating to have an LLM describe an API or piece of functionality that fulfills all requirements perfectly, only to find it was a hallucination. They are impressive sometimes though. Recently I had an issue with a regression in some of our test capabilities after a pivot to Microsoft Orleans. After trying everything I could think of, I asked Sonnet 4.5, and it came up with a solution to a problem I could not even find described on the internet, let alone solved. That was quite impressive, but I almost gave up on it because it hallucinated wildly before and after the workable solution.
The same stuff happens when summarizing documentation. In that regard, I would say that, at best, modern LLMs are only good for finding an entrypoint into the docs.
