About Bitpart AI
Bitpart AI is an AI engine for authoring and running populations of non player characters in game worlds. It is built for game designers, writers and animators who want characters that converse with the player and each other and interact with objects, without needing programmers to script every behavior. The vendor states it was built by developers who worked on franchises including Halo, FEAR, The Last of Us and Everquest.
The system has two halves. Non engineers create dialogue and interaction content in the Coppola authoring tool, using a simple interface where they type or choose from dropdowns, and can optionally use AI assistance to import human written scripts or draft rough content from prompts. A Rehearsal text simulation lets them test dialogue and action sequences before running them in engine. At runtime, an AI Director drives characters in Unreal, with behavior that varies by memories, relationships, traits and game state. The runtime is described as an optimized, deterministic hierarchical task network planner, and worlds can scale to hundreds of active characters, or thousands using streaming and level of detail. Pre configured Archetypes supply characters with animation, behavior, dialogue and props.
The Solo Developer plan is free, with unlimited use of the Fab version of the SDK, planner, archetype packs and Coppola, plus community support. The Pro plan costs $5,000 per title per year during development, for teams of 10 or fewer, and adds a shared organization, early feature access, an AI design assistant in Coppola and dedicated support with a 24 hour response time. The Studio plan is custom priced for publishers and teams larger than 10. The runtime is free and no royalty is charged when a game ships.
