I don't think any of the current consumer LLM tools use embeddings for web search. Instead they do it at the text level.
The evidence for this is the COT summary with ChatGPT - I have seen something where the the LLM uses quotes to grep on the web.
Embeddings seem good in theory but in practice its probably best to ask an LLM to do a deep search instead by giving it instructions like "use synonyms and common typos and grep".
Does any one know any live example of a consumer product using embeddings?
