A: Hi,

Thanks for your question. Currently the system allows for a pdf upload with upto 50 mb size and about 1000 pages if it is text heavy. For OCR /image based documents, upto 20 pages and 10 images per page is the limit, although we are working to improve this limit.

Regarding using GPT-4o mini, our current philosophy has been to use the best llm model to ensure accuracy and authenticity as the primary focus is to support research use cases where this is critical. Having said that, we will consider your suggestion if more users come up with requests for providing an alternative for the rate limit constraints.
