Unity offers Unity AI Generators, a set of tools built into the Unity Editor that lets game developers create 2D sprites, textures, materials, animations, sounds, and 3D objects from text prompts or reference images, available in beta since August 2025 for users on Unity 6.3 or later.

Unity AI Generators replaced the retired Unity Muse suite (retired October 1, 2025) and use a mix of Unity's own first-party models and third-party partner models, including LoRAs from Scenario and Layer AI trained on Stable Diffusion and Flux foundation models. All generated assets are automatically tagged with 'UnityAI' metadata (EXIF data), making them searchable and manageable within the project. The Generators run in Unity Cloud, not locally. A 3D Object Generator, which produces static mesh prefabs from text prompts or reference images using the Hunyuan 3D model, was added to the Generators package and is documented in the official Unity 6.3 release. As of November 2025, the video-to-motion animation model was discontinued after a partner deprecated that service; Unity has stated it is evaluating replacement partners.
