AI Dungeon is a text adventure game that uses artificial intelligence to generate random storylines in response to player-submitted stimuli.

This creation used an early version of the GPT-2 natural-language-generating neural network, created by OpenAI,[19][20] allowing it to generate its original adventure narratives.

[15] This training material included approximately 30 megabytes of content web-scraped from chooseyourstory.com (an online community website of content inspired by interactive gamebooks, written by contributors of multiple skill levels, using logic of differing complexity[27]) and multiple D&D rulebooks and adventures.

[29] It was accessible via Google Colab, an online tool for data scientists and AI researchers that allows for free execution of code on Google-hosted machines.

[30][9] It could also be run locally on a PC, but in both cases, it required players to download the full model, around 5 gigabytes of data.

[9] Within days of the initial release, this mandatory download resulted in bandwidth charges of over $20,000, forcing the temporary shut-down of the game until a peer-to-peer alternative solution was established.

[32][33][9] Other members of this team included Thorsten Kreutz for the game's long-term strategy and the creator's brother, Alan Walton, for hosting infrastructure.

"[4]Campbell Bird of 148Apps also awarded this edition of the game 4 out of 5 stars in his review, also praising its creativity whilst criticizing the lack of memory for previous content:[39]"AI Dungeon is like doing improv with a partner who is equal parts enthusiastic and drunk... [It] is a game that's charming, occasionally frustrating, but mostly just impressive in its raw creativity and spirit.

[5] The AI's tendency to create graphic and sexual content despite not being prompted by players was noted by reviewers, including Lindsay Bicknell.

Latitude CEO Nick Walton and researcher Suchin Gururangan responded to such concerns, stating that the behavior was unexpected and reasoning that such a thing occurs due to a lack of strict constraints placed on the GPT-3 model.

Although the game was primarily trained using text adventures, training content for the GPT models themselves included large amounts of web content (including the entirety of the English-language Wikipedia), thereby allowing the game to adapt to areas outside of this core focus.

[49][41][50][51] The filter frequently flagged false positives due to wording (terms like "eight-year-old laptop" misinterpreted as the age of a child), affecting both pornographic and non-pornographic stories.

Controversy and review bombing of AI Dungeon occurred as a result of the moderation system, citing false positives and a lack of communication between Latitude and its user base following the change.

This addition received backlash from users, and Latitude would add a beta system in response, allowing storing of actions through watching advertisements.
