Suno

Suno v5

  • Best-in-class vocals, capturing whispers, vibrato, and emotional nuance
  • Full song structure with proper verse, chorus, and bridge arrangement
  • Rap and spoken word still sound noticeably synthetic
  • No official public API yet; a partner API was only announced as exploratory in July 2026
Udio

Udio v4

  • Inpainting lets you regenerate one section without redoing the whole track
  • Stem separation and an official API for paid tiers
  • Public documentation of the v4 release is thin compared with Suno’s
  • Check licensing terms carefully before commercial use of generated music
ElevenLabs

ElevenLabs (Voice & Music)

  • Trained on licensed catalogs, giving strong legal safety for commercial use
  • Realistic voice cloning and text-to-speech with broad API access
  • Music composition quality trails Suno and Udio
  • Generation is slower and pricier than most competitors
Google

Google Lyria 3

  • Generates vocals with auto-written lyrics from text, image, or video prompts
  • High output quality for short-form music
  • Full-length songs need the Lyria 3 Pro tier; the base model makes short clips
  • Google has already moved on to Lyria 3.5 in its own music tools
