I enabled `ai embeddings semantic quick search enabled` but it gives error 500. It works here, and error 500 quite often happends because of issues of servers, aka. at my end, but I’m a bit lost how to start solving out this.
I upgraded a couple days ago, but it hasn’t work ever. Sementic suggestions works just nice when searched as usual.
Used model is GPT-4 Turbo, and embeddings model is text-embedding-3-small — if that matters. I used large at some point, but changed it to small, because I didn’t get wanted results, and at that point OpenAI has some issues with large-model.
Safe-mode doesn’t help.
And error I get:

That’s an experimental feature that requires you to enable per post embeddings and to use a re-ranker model, which we are still evaluating the feasibility of.
I will move this setting to a hidden one so people don’t enable it by mistake.
