AI content's LSI issues?

hey guys, following up on my earlier post about my AI tool suddenly struggling with semantic relevance.

i'm trying to figure out what usually causes a sudden drop here, especially with AI-generated stuff.

• are there common technical changes in AI models that affect how they handle latent semantic indexing?
• or is it more likely an issue with the data I'm feeding it, like new topics being too niche?

just trying to narrow down the potential culprits before i dive deep into logs.

thanks in advance!
