Paid version clarification

Hi @nunospot

Thank you for keeping using the plugin! The difference is the underlying embedding model.
Free runs on OpenAI’s text-embedding-3-small (1,536 dimensions). Standard and Pro upgrade to text-embedding-3-large (3,072 dimensions).

More dimensions means more “descriptive resolution”, basically the model can separate concepts that -small mashes together. Two concrete places you’ll feel this:

1. Multilingual queries. it’s works better than the free one
2. Nuanced descriptive queries. “Something warm but breathable for hiking” free version (small) tends to lump insulated jackets and breathable midlayers together, while the paid (large) distinguishes them. Same thing for technical proximity, like “USB-C hub with HDMI 4K 60Hz” separating cleanly from 30Hz variants. For English-only, short queries against literal product names, you probably won’t feel much difference between the two models. If most of your traffic
   is that shape, the Free plan is genuinely enough. Longer write-up with the benchmark numbers and side-by-side examples: https://wp-search.ai/text-embedding-3-small-vs-large/

If you want, share one or two of your own queries where Free feels weak and I can tell you whether, like large would fix it or whether it’s a different problem (like content missing from the index).

hope this helps!
