What it does
Stability AI's text-to-audio tool for generating music and audio clips.
Unity's AI tools (Unity is retiring the "Unity AI" name): an in-editor assistant for project questions, code and Editor actions, plus generators for images, textures, sounds, 3D models and animations, metered in Unity Credits. The Unity CLI, MCP server and Unity's official agent plugin are free.
Verdict
For generated music and audio clips; the free plan is non-commercial, while paid plans include a commercial licence.
For Unity 6 users who want AI inside the editor: credits are included on Pro, Enterprise and Industry, while Personal gets a 14-day trial and then a paid subscription. Unity says you own the outputs, but third-party generator terms also apply.

Unity's AI Guiding Principles say you own your input and output data, regardless of the partner model used, and that you're responsible for making sure generated assets don't infringe third-party rights. Using the generators is also governed by third-party terms (Layer, Scenario, Uthana). Generated assets carry "UnityAI" metadata. Commercial-use terms for outputs aren't stated separately. source
