GPT4 is only trained on data up to 2021, and the library has commits as recent as two months ago. So I think that may be a hallucination. A quick google also reveals nothing like that. It's been a while but I also remember HSNW having undesirable characteristics for large scale vector search (compared to other methods), so I'm not sure there. I did do a quick search and saw there are methods that make it more suitable, but again it's been 3 years now since I've used anything in this area. Edit: I got curious, https://ann-benchmarks.com/ https://ann-benchmarks.com/ So I was mis remembering a bit, HSNW is pretty good overall depending on your implementation!
