Google AI Studio has a massive token window. I’ve tested it out using a setup where I feed a templated prompt into Gemini 2.5 pro along with a PDF of any particular campaign (courtesy of Anna’s Archive), and the campaign actually plays out really well.
Here’s the prompt and a readme I put into google drive Just be sure to change the {character name/race/class} for your character in the prompt before you submit it.
Since it’s a large model, a 50 response session might have an equivalent energy cost of running a microwave for 7 minutes (or more – and of course that doesn’t count the energy used in the training of the model as well), so make of that what you will.
