Why build models at all
General-purpose models are capable and not specialised for this domain. They do not know Roblox's constraints, the studio's conventions, or how an NPC in a specific world should reason.
Project Prometheus explores models specialised for game development, simulation, moderation and interactive entertainment, where a smaller specialised model can outperform a larger general one.
Latency as a design constraint
A model driving a character in real time has a latency budget measured in hundreds of milliseconds. That constraint favours smaller models tuned for the task over the largest available model.
Real-time game agents are the sharpest version of this: reasoning about a live world under a hard deadline is a different problem from producing a good answer eventually.
Moderation and multi-modality
Moderation models are a distinct research track with different requirements, valuing consistency and explainability over creativity, since decisions must be defensible on appeal.
Vision-language and speech models extend the work to images, assets and voice, and multi-agent research addresses what happens when several model-driven characters interact with each other rather than only with players.
