A way to track costs per doc

[salahuddinfa]

It would be good to have a way to track costs, any way to do this?

Also Can we use any other models other than OpenAI

Good point. Cost tracking would be useful. We are considering exposing simple usage metrics (e.g., tokens processed per query / per document) so that teams can plug them into their own cost dashboards or billing systems. Longer-term, we could add built-in analytics to track usage and estimate spend.

As for models, PageIndex itself is model-agnostic. The examples currently use OpenAI models, but you can swap in any LLM provider (Anthropic, DeepSeek, local models, etc). We will work on adding docs and helper utilities to make that easier.
