You realize that an index is still necessary for RAG?

Where do you think the results used by Perplexity, Open AI etc. come from?

This reminds me of the twitter conversation I saw - someone cheering on the dismantling of US meteorological service, because they have weather apps on their phone.

All the apps use the norwegian service anyway

There is at least one organization doing actual embedding-based search (Exa). I wrote about this a bit: https://docs.osmarks.net/hypha/osmarks.net_web_search_plan_%....

Yes, I know Exa and have used them in the past for some side projects. Great product.

But that's still an index. Google also internally uses combination of traditional and sematic/embedding based indices.
