I have a couple of long form content pieces (about 30 pages each, or around 20k words total). I want to give GPT some instructions and input both of these pieces of content to create a combined document, taking elements from both and creating a single, merged piece. Total output would be between 20-40k words. I'm using the API in an external tool (Team GPT) and it has the option to use various versions up to GPT 4. Is it possible to put all this content in and have it process the document plus provide output, or would I need to use a different tool/method for that?
