Ubisoft describes writers defining character background and behavior, followed by iteration on how models respond within those constraints. The authoring work remains part of the system.
Start with one character, a specific scene and a limited objective. Test both a normal conversation and a request that contradicts the character’s knowledge or motivation.
What this does not establish
Ubisoft explicitly presents a prototype, not a feature shipped across its games. The page does not establish a current product subscription or a repeatable workflow for independent developers.
