Suno deployed an AI music generation platform that converts a user's plain-text description—such as a genre, mood, or lyric idea—into a fully produced song with vocals, melody, and instrumentation, typically in under 60 seconds. The platform has been available to the general public since December 2023, with free and paid subscription tiers.

The system uses transformer-based generative audio models, described internally as 'Bark' for vocals and 'Chirp' for instrumentation, which were trained on audio data to learn patterns of rhythm, harmony, and timbre. Users can input a natural-language prompt (e.g., 'upbeat indie pop about summer road trips'), custom lyrics, or an audio recording, and the AI produces a downloadable audio track. As of late 2025, paid tiers (Pro at ~$10/month, Premier at ~$30/month) run the v5 model enabling tracks up to 8 minutes, while the free Basic plan runs v4.5 with a limit of 50 credits per day for non-commercial use.
