Microsoft announces 'Muse', a game generation AI model that can generate new games based on visuals and player controller operations
On February 19, 2025, Microsoft announced Muse , a generative AI model specialized for games. Muse is said to enable AI to generate detailed 3D game worlds, including in-game physics and game responses to player controller inputs.

Muse was trained on the multiplayer battle arena game ' Bleeding Edge ' by Ninja Theory, a game developer based in Cambridge, UK, and is able to grasp the game's physics and how it responds to the player's controller inputs in detail. Approximately 100 NVIDIA V100 GPUs were used to train Muse.
This allows the AI to generate consistent and diverse gameplay. In addition, Muse can learn from games released on old hardware that many users can no longer play, and optimize them for any device. Microsoft says, 'We hope that Muse will fundamentally change the way classic games are stored and experienced, making it easier for more players to access past games.'
Muse allows you to input a single image as your initial prompt and generate an infinite number of gameplays linked to that image.
In addition, you can direct the actions of the generated in-game characters by operating the controller.
In addition, Microsoft is developing tools that benefit all users, including Muse, based on responsible AI policies that emphasize fairness, reliability, safety, privacy and security, inclusiveness, transparency and accountability. Microsoft also said, 'We believe it is important to continue to incorporate breakthroughs in generative AI, which are updated daily, and to support the industry and game development community in a collaborative and responsible manner.'
In addition, Microsoft has released Muse's open weights, interfaces for using Muse, sample data, etc. on Azure AI Foundry . In addition, 'We plan to release a short interactive AI game experience on Copilot Labs soon, providing an open opportunity for anyone to participate in this research project.'
Looking ahead, Xbox said, 'We believe AI has the potential to eliminate barriers and friction between gamers and creators,' and announced that it plans to make groundbreaking AI products publicly available soon, providing players and creators with the opportunity to collaborate and test new AI features and capabilities.
