Graded C on resilience. In Vannus's assessment it builds its own AI model — acceptable, with limits worth knowing.
Suno v5.5 allows you to create Custom Models based on your songs.
Vannus grades Suno against nine dimensions of trust — data sovereignty, training privacy, compliance posture, operational resilience, exit portability, and more. The heaviest criterion asks whether the tool builds its own AI or resells someone else's model; where the vendor discloses it, the grade cites the vendor's own documentation. No paid placements — scoring is walled off from affiliate revenue. See the methodology →
