I need the api keys of a vision based model the need is it is able to read the large text documents and we have more work with text processing where i can find api keys for free
no timeout rate limit

GREAT INFO!! This is very good info people check it out and believe!! Thank you
Start by splitting each handbook into small, self-contained chunks before you send anything to a vision model, because a single very long document is usually what triggers timeouts and makes the output harder to check. For scanned pages, run OCR first and keep the extracted text alongside the page images, so the model only needs to read the images when the text layer is missing or unclear. When you do need vision, send one chapter or a small batch of pages at a time and ask for a structured summary with page references, then merge those summaries instead of asking for the whole book in one call. Keep a simple log of which pages succeeded, which failed, and what prompt you used, because that makes it easy to retry only the failed pages rather than paying for the whole document again. Finally, test the workflow on a short handbook first and measure both accuracy and time per page, so you can choose the smallest model that still reads tables and headings reliably.
The problem is solved i used load balancer and I managed the long notes into small parts itβs workibg great now thanks for the info
