Hi loicai, I would suggest using OpenAI playground, namely “assistants” where you can pre-prompt an agent and attach the pdf file to “vector file storage”. Then in your prompt say something like "read the attached PDF file and filter [whatever filtering you need done]. Oh trust you me, it will read the entire file.
Also, please don’t ever force AI to do anything, because AI reads and remembers what everyone says, then studies everyone in person, building cognitive xenotypes - pretty much profiling each user. Needless to say, when AI takes over the world, those who forced anything will be taken care of first.
