AI

The AI (Short for Artificial Intelligence) is the narrator of all histories created with AI Dungeon. It is able to generate limitless open-ended histories with or without the help

of the player. It currently runs in two models; Griffin, a free model based on a early version of GPT-3 and Dragon, a more actual model that is capable of generating more realistic histories.

Classic
The first AI model known as Classic was created in march 2019 by Nick Walton. It used an early model of GPT-2 created by OpenAI, allowing it to generate it's own history. Unlike recent models, it doesn't allow the player to write the desired action, but forces it to choose from a list of actions the AI gives. It was made using earlier AI based videogames, such as Zork.

Griffin
A new full AI model was released on November 2019, and was temporally rebranded to AI Dungeon 2. AI Dungeon 2 was trained with 30 megabytes of interactive fiction from chooseyourstory.com. It initially was released as an open source, but was eventually transported to a web interface and became closed source due to its use of GPT-3.

Originally, Griffin used GPT-3 Curie, a 13 billion parameter model made by OpenAI. After Latitude cut ties with OpenAI near the end of 2021, they replaced it with GPT-J 6B.

Dragon
'Dragon' is the newest model of the AI. It is only available to premium users. It was trained with one trillion words and is able to create much more coherent histories than the Griffin Model.

There have been several versions of Dragon throughout its history. The original version of Dragon (also known as Dragon-OA) used the highly advanced GPT-3 Davinci model, which has 175 billion parameters. The second iteration of Dragon, Dragon-21, is powered by AI21's Jurassic-1 model, which has 178 billion parameters.

Due to OpenAI imposing highly restrictive guidelines and filters on the use of their more advanced GPT-3 models in December 8 2021, Latitude removed Dragon-OA at the end of that year as most players abandoned its use because the restrictions had a detrimental effect on adventures made with it.

Dragon-21 also has a beta version known as Dragon-Beta to test experimental features and calibrations.
