Suno adds watermarks and download caps to rein in AI-music abuse

Suno is adding invisible watermarks to audio generated by its models and tightening download rules as it tries to make its service harder to use for mass distribution of AI music. The company says the changes are meant to preserve normal creative use while making large-scale abuse more difficult. In a blog post on 6 Aug, Suno said it will introduce audio watermarking and fingerprinting in the coming weeks so songs made on the platform can be identified if they are shared elsewhere. Mikey Shulman said the move is intended to meet “emerging industry standards” for labeling AI content, and the company said the tools are designed to be durable and resistant to tampering without affecting the listening experience. Suno also said the watermark system will give platforms the option to mark content as AI or block it entirely. It described the watermark as an invisible code embedded in the waveform of every generated track, and said a detector trained on that signature will help partners combat fraud and misuse. The company stressed that the tools are not meant to decide whether a song is good, meaningful or human enough. The download policy takes effect on 3 Sept. Free users will be limited to seven lifetime trial downloads for personal, non-commercial use. Pro users will get 20 downloads a month with commercial rights, and Premier users 60 downloads a month with commercial rights. Premier subscribers using Suno Studio will have no download limits, and users can buy additional downloads if they go beyond their allowance. Suno said the limits apply only to files downloaded off the platform, not to streaming or sharing on Suno, which remain unlimited on every plan. The FAQ says the caps will apply to all downloads from 3 Sept, including songs created before that date. The company said one song counts as one download regardless of format, downloading the same song twice counts only once, failed or interrupted downloads do not count against a quota, and stems are treated as part of the song rather than separate downloads. Monthly allowances reset on the billing date, and unused downloads do not roll over. Suno framed the policy as a way to keep the platform focused on intentional music creation and to protect professional, creative and personal use. It also updated its Community Guidelines to spell out prohibitions against recreating existing songs, uploading material users do not have rights to use, using someone’s voice or likeness without permission, and engaging in scams, spam, fake engagement, bot evasion or deceptive audio presented as authentic. The company said its Trust & Safety team reviews content proactively and investigates reports through in-app tools. Enforcement can range from warnings and temporary suspensions to permanent bans and, where appropriate, referrals to authorities. The changes come as Suno faces wider legal scrutiny. A German court recently found the company had violated Germany’s music licensing rules, and Suno is also being sued in the United States by Universal and Sony over copyright infringement. Billboard reported that the download caps were first promised in Suno’s settlement with Warner Music Group last year.
