A: Page count is not a good way to measure book size because word count by page can vary a lot. Typical non-ficiton books are 80K to 120K words. Assuming you don't use advanced AI models (I would not - they are too expensive, and provide marginal improvement) you can do 3 books and have credits left for sources and training one or two human models.

If you want to crank up volume, you need a BYOK account, and external API keys from OpenAI and Gemini.
