LLMs For Fan Fiction


Man is super happy on his latest Fan Fiction he Created on his computer with Open AI and Chat GPT

One of the more interesting use cases I’ve come across with will make fans of tons of film and television happy. You can use ChatGPT to get lost in your favorite worlds and either join in crazy new adventures or re-write bad plot lines.


For instance, let’s say you have an existing plot for a movie, and you’d like to change part of the outcome. Fortunately, most popular movies are so popular and so much has been written about them that LLMs already naturally know the characters and have a good representation of their personalities. That’s incredibly good for fans, because you don’t have to explain much and can keep your token count very low if you stick closely to the existing characters of the show. So, when you want to make a change all you need to tell the LLM is where you want to start and what you want to discuss and poof, you’re now in that scene.


The more popular shows will be easier to work with because they are so heavily indexed by OpenAI’s ChatGPT for instance. So, some obscure B movie that no one has ever heard of? Not a great choice for this without a ton of prompting to give it context. But the mega-popular multi-season shows or box office smash movies? Perfect.


So, let’s say you hate the last season of Lost and want it to all end in a fiery volcano representing hell… no problem, just write up the character you want to play as and the scene and you’re there. Or let’s say you hate the last season of Battlestar Galactica and want the Cylons to take a different approach... fine! Write it up. Those are examples of modifications to existing plotlines.


But what about if you want to start an entirely new plotline. Like what if you want Agent Fox Mulder to find his sister in the X-Files? Or what if you want to live another adventure of Firefly. Easy – just set the stage and start playing along.


Normal caveats apply – it will often forget that you’re in role-play, so you’ll need to remind it with the line that starts with “Important”. It also gets confused if you have too many characters “on set” at the same time. It’s a failing of the reasoning engine and the fact it doesn’t really keep state of characters. So, the fewer characters on set that it needs to manage, the better the outcome will be.


This can completely revolutionize how people interact with movies and TV after the fact, giving them entirely new and frankly much faster paths to read about, and dare I say, interact with their favorite characters. That’s a huge change in how people can discuss topics with their favorite characters. Have a weird ailment – talk with Doctor House about it. Want to escape to a foreign land, become Doctor Who’s new companion. The world, and indeed, every world is your oyster.


As an omnipotent being within the LLM you actually have superpowers too – you can re-write anything you want at any time, or cause a character to act in ways they may not normally. For instance, you might force the Wicked Witch of the West in the Wizard of Oz to fall in love with you, or cause Batman to take a life instead of always preserving it. That can lead to very interesting outcomes. So, without further ado, here are some examples that might get your brain going, with the sample associated prompts. I’d love to hear anything interesting you come up with!
