AI music generation

Generate a track from a description on /app/tracks/generate, or an AI audio reply from a version comment. Lyria 3 Pro and Clip through OpenRouter, priced per generation. Admin preview billed to Aden's OpenRouter balance until the Polar meter takes over. Every generated track carries `ai` + `ai:<model>` tags.

What it is

Describe a piece of music and a model plays it for you. On the generate page the result becomes a new track in your team, with the audio as its first version. In a version's comments the result comes back as a reply with the audio attached, so you can ask for "a brighter synth line for the bridge" right where the conversation about the bridge is happening.

Each generation is priced per song or per clip. The price is on the button before you click it. While the feature is in admin preview, Aden carries the cost.

Using it

On the generate page

Open Generate from the create-track page header (admins only for now), or go to /app/tracks/generate.
Describe the music. Genre, mood, instruments and tempo all help.
Write lyrics, leave the box empty for the model to write its own, or turn on Instrumental.
Give it a title if you have one, pick a model, click Generate.
A minute or two later the track shows up in the list on the right, with a play button and a link to its page. It is a normal track: status idea, tags ai and ai:<model>, the prompt as its description.

In a version's comments

From your draft. Type what you want in the comment box and click the sparkles button next to Comment (or next to Reply in a thread). Pick a model and generate. The draft is the prompt; the audio arrives as an AI reply in the thread.
From someone's comment. Hover a comment and click its sparkles action. That comment's text is the prompt, and the reply lands under it, pinned to the same timestamp when the comment had one.

An AI reply shows an AI · model badge. Its audio plays inline like any attachment, and Add as stem lays it onto the version's timeline.

Finding AI-generated work later

Every generated version and its track get the tags ai and ai:<model>, for example ai:lyria-3-pro. Group the tracks board by tag or filter the list on ai to see everything a model touched.

Who can generate

Admins only, while the feature is in preview. Non-admins do not see the generate link or the comment buttons, and the page says so if they open it directly. Guests on share links cannot generate.
