I'd like to send the OpenAI's API, the text from various PDF's. Specifically, the [Summarize for a 2nd grader](https://beta.openai.com/examples/default-summarize) or the [TL;DR summarization](https://beta.openai.com/examples/default-tldr-summary) API's. I can extract the text from PDF's using `PyMuPDF` and prepare the OpenAI prompt. **Question:** How best to prepare the `prompt` when the token count is longer than the allowed 2049? - Do I just truncate the text? - Or is there a way to sample the text to "compress" it to lose key points?
