Ten holiday ad tracks: Lyria 3.5 at Google's list vs Sume Music

Ten holiday ad tracks cost $0.80 at Google's Lyria 3.5 list price and $1.25 on Sume Music, a difference of $0.45. For a campaign that is a rounding error next to the media spend, but it is worth knowing what it buys.

Google's Gemini API pricing page, read on 2026-10-04, lists Lyria 3.5 at $0.08 per song. Sume's Music Router uses Lyria 3.5 as its current engine and bills $0.125 per audio generation.

The ten-track budget

What the Sume price includes

On Sume the track is a job like any other: it lands as a hosted audio asset you can pass straight to a Timeline render, a caption job or an avatar video. The prompt is 1 to 5,000 characters, and the docs say a duration field is rejected, so you set length in the prompt itself, for example by asking for a 2-minute track or by writing timed sections.

If you generate in a script against Google's API directly, you pay less per song and handle storage and hand-off yourself. If you only need a few tracks for one campaign, the $0.45 difference does not decide anything, and convenience can.

A practical order of work

• Write ten short briefs, one per ad cut, with the mood and the tempo you want.
• Generate all ten, listen, and keep the best three.
• Reserve a retry or two per track in your budget, since taste is not deterministic.
