Divinity: Original Sin 1 added a feature called AI Personalities that lets the game's second main character make dialogue decisions on their own based on a personality type chosen by the player. This is a traditional rule-based system — not machine learning — and was not carried forward to later Larian games in the same form.
Details
Introduced in the game's first official patch in 2014, the system offered five or more personality presets — including Loyal, Rascal, Maniac, and Priest — each defined by weighted preferences across behavioral trait pairs such as compassionate versus heartless, or independent versus obedient. When the two protagonists disagreed during dialogue, the second character's response was determined by these weights. Players could also define custom personalities. CEO Vincke described the system at the time as making co-op play feel more like playing with a human companion.

Other practices by Larian Studios
Creative GenLarian uses machine learning models to clean up and adapt motion capture data from human actors so it can be applied to game characters of wildly different body shapes — like a tiny halfling or a towering dragonborn. These models are trained only on data Larian owns, and their output appears in shipped games.Creative GenLarian's artists experimented with generative AI tools to explore rough visual ideas at the very earliest stage of concept art development — similar to how a designer might flip through reference books. After significant backlash from fans and former employees in December 2025, the studio formally banned generative AI from all concept art work in January 2026.Creative GenA small group at Larian Studios tested generative AI text generation tools for research purposes during early development of Divinity, the studio's next RPG. Writing Director Adam Smith stated at a January 9, 2026 Reddit AMA that the tools scored '3/10 at best' and that no AI-generated text touches dialogue, journal entries, or any other written content in Divinity.
