Suno vs Udio
AI music: fidelity versus something you can actually ship? Scores from the RXed AI Periodic Table v1.0 — identical 20-element scale, deterministic overall. How we audit →
At a glance
Scope = elements of the AI stack in the tool’s stated scope (dashed = honestly out of scope, never a penalty). Quality = how well it scores on what it covers. No single number — both axes, always.
The verdict
Udio (Scope 8/20 · Quality 4/10) still wins on raw audio fidelity and is the only AI music tool with major-label licensing — but its 2025 download ban and licensing transition make it a gamble for any workflow that needs to export audio today. Suno (Scope 9/20 · Quality 6/10) is the one you can build a routine on: commercial rights from €9/month, 2M+ paid subscribers, the stronger underlying model score (Lg 8.5) — though there is no public API (Pc 1.5) and two of the three major labels are still suing. Neither is an integration platform; both are consumer instruments. If you need music in your business content this quarter, Suno. If you need the absolute best-sounding output and can wait out the lawyers, Udio.
Where the quality sits
Family mean over covered elements only — a dash means the family is honestly outside that tool’s scope.
