Google researchers present UNBOUNDED: an infinite generative interactive game based on generative AI models

Games can be considered finite or infinite. Finite games are structured around achieving a specific outcome, with established rules, boundaries, and a clear endpoint. In contrast, infinite games focus on continuing to play indefinitely, adapting regulations and limits. Most traditional video games are finite because programming and graphic design limitations limit them to a fixed set of mechanics and visual resources, making them closed systems with limited actions and specific win conditions.

However, recent advances in generative ai have opened up new possibilities for creating an infinite gaming experience. With large language models capable of handling complex game mechanics, character interactions, dynamic storytelling, and advanced visual models that produce high-quality, cue-based graphics, we now have the tools to generate open-ended games and evolving narratives. This combination allows stories and interactions to be continually adapted, setting the stage for a new game that could run without fixed boundaries.

Researchers from Google and the University of North Carolina at Chapel Hill presented UNBOUNDED, an infinite generative game designed to go beyond the traditional, finite limits of video games using ai. Inspired by life simulations and role-playing games, UNBOUNDED uses a specialized language model to create dynamic game mechanics, stories, character interactions, and a regional image adapter that generates consistent images across various scenes. Players participate in a simulated world where characters evolve based on their choices, creating open-ended interactions in real time. This framework highlights a new paradigm in which generative models govern game content and logic, allowing for immersive and limitless gameplay.

UNBOUNDED is an infinite interactive game powered by language models and text-to-image generation, allowing players to create custom characters, explore dynamic worlds, and engage in open-ended gameplay. The game achieves real-time interaction with high-resolution images using latent consistency models (LCM) for efficient text-to-image generation. Maintains character and environment consistency through DreamBooth and a novel regional IP adapter that separates character and environment conditioning. The game engine, powered by large language models, simulates character actions and world environments with near-instantaneous response times, achieved by merging capabilities into the smaller, faster Gemma-2B model for enhanced interactivity.

The evaluation shows that the regional IP adapter with block drop achieves strong environment and character consistency, outperforming previous methods on metrics related to alignment and image quality. Quantitatively, it maintains coherence between setting and characters while preserving semantic alignment with the message. Qualitatively, the approach demonstrates consistent generation of characters and environments that match the specified conditions. Additionally, the use of dynamic block dropping further improves image alignment and accuracy. When comparing language models to game engines, model performance benefits from using larger data sets, effectively closing the gap with leading models.

UNBOUNDED is an innovative generative game that expands beyond conventional finite designs using advanced generative models. This game integrates a distilled language model for real-time interactive narrative and character development and a rapid dissemination model with a new regional IP adapter, achieving visual consistency across all scenes. Building on the concept of infinite games, UNBOUNDED enables open-ended gameplay, where users interact with virtual characters in dynamic and evolving environments. Technical advances in language and vision models ensure consistency in character behavior, story progression, and scene coherence, providing an immersive, fluid experience unmatched by traditional approaches.
