Microsoft’s Muse is built on the World and Human Action Model (WHAM) and is intended to enhance developers’ creativity.

Microsoft says Muse was developed around the idea of how innovations in AI capabilities can support creativity.

Muse is Microsoft's new generative AI for game development that promises to be a gameplay concept tool – it will ideate playable ideas, building game visuals, controller inputs and more. It sounds groundbreaking but Muse feels like a tech experiment rather than the game development revolution Microsoft is pitching.
