Table of ContentsAbout Our Free AI Models
AI Dungeon uses AI language models to drive game experiences. We also offer several AI image models to generate pictures during gameplay. Each of these models has different characteristics, so choose the one that best fits your play style.
The AI text models offered by AI Dungeon are divided into two broad categories: Free and Premium.
Free Models are available to non-subscribers without limits on the number of actions that can be taken, but at shorter context lengths than available to subscribers.
Dynamic Small
Dynamic Small is a system that automatically switches between our free models to reduce repetition and provide a smoother, more varied storytelling experience. Instead of always using a single AI, it alternates between different models for different actions—like having multiple storytellers take turns advancing your tale. There are no settings or instructions to manage or tune—the system handles everything automatically. This can help keep stories fresh and prevent the AI from getting stuck in repetitive patterns. Perfect for players who want a great experience without managing everything themselves.
Wayfarer Small
Wayfarer Small is an inhouse finetune of Mistral NeMo 12b, created specifically for AI Dungeon to deliver stories with genuine conflict and tension. This latest iteration incorporates dataset improvements designed to cut repetition, increase name diversity, and focus on story-relevant details. The result is a model that creates narratives where choices have real consequences, success feels earned, and failure is always possible.
Madness
Madness is an open-source finetune of Mistral NeMo 12b that specializes in vivid prose with a focus on darker themes. The model excels at horror, visceral description, and intense emotional moments. As its name suggests, don't expect many "happily ever after" endings.
