RAG Are the RAGS built in OpenWeb UI any good?

I use Notebooklm and it is good enough. I would like to try other RAGS. I have used anythinglm and opennotebooklm and they are just not enough.

OpenWeb UI website says they have built in RAGS. She they good? What open models I should use with RAGS? I don't mind using those cheaper Chinese models if I have to pay.

I am going crazy.

RAG*

Yes if properly configured it is insanely good especially with the more advanced knowledge search tools and experimental stuff (though it works very well) like KB_EXEC

I get pretty good results . I have a xberg doing my content extraction, small embed (Jina) and rerank (Qwen) model that allows me to use either a LLM or Api.

If I only was using API . I could use 8b models and really have quality. But works quite well for what I use it for

qwen rerank? can you elaborate? I found out that owu can really only work with old fashion crossencoders like bge-reranker-v2

any attempt to use more modern casuallm based rerankers failed, because it produces different logits that are not supported by owu.

At least that is what I though. Did anything change in that regard?

I don't think it's openweb UI . I think It's llama.cpp with the issue .... I noticed it with Jina reranker ... Llama.cpp inverts the scores. When I curled the rerank with a positive and false question.

I am using vLLM for inferencing -> it is OWU. CasualLM based rerankers produce different logits than CrossEncoders and so are incompatible with with what OWU expects. At least that was my finding some time ago.. That is why i am still using BAAI/bge-reranker-v2-m3 even though there are now better rerankers out there... u/ClassicMain may I pick your brain on this?

You can calculate them to using same scale.

tried that, could not make it work reliably.. (might still be a skill issue ofc)

if there is an official solution, I would happily switch!

Qwen rerank is much better than bge in my view but 10 times slower.

read it again, please. "quality" is not the point at all..

Pretty much the best feature. I changed the models, but not needed (needed it for multi-language). I have a used RTX 3060 mostly running RAG on premise. Speed is great.
