AI music startup Suno has replaced its entire previous model lineup with a new “v6” family of systems trained exclusively on licensed music from Warner Music Group (WMG), BMG and distributor Believe, as multiple copyright lawsuits continue to mount against the company. The move marks a strategic pivot toward licensed training data while legal battles with Universal Music Group (UMG), Sony Music and other rights holders remain unresolved.
New v6 models and rollout
Suno announced three new models on Wednesday:
Suno v6: A polished, “reliable and steerable” base model for paying Pro and Premier subscribers.
Suno v6‑wild: An experimental variant designed for more unpredictable, ideation-focused outputs, also limited to paid tiers.
Suno v6‑mini: A faster, lighter model made available to all users, including free-tier accounts.
The company said it will retire all earlier models as v6 rolls out globally, effectively switching the entire platform onto the new generation. New capabilities include partial song editing, mashups using multiple sources, audio isolation and sampling features, according to Suno’s product announcements.
Licensing deals behind v6
The v6 suite was developed in partnership with WMG, BMG and Believe, whose catalogs form the licensed training foundation for the new systems. Warner originally joined the 2024 copyright lawsuit against Suno but exited after a November 2025 settlement that required Suno to build new models using licensed music. BMG followed with a global licensing agreement in August 2026 covering its recorded music and publishing rights. Believe’s TuneCore distribution platform also entered an opt‑in content partnership so participating artists and labels can allow their tracks to be used in training.
Suno’s chief product officer Jack Brody told Axios the v6 models are faster, higher quality and better at following detailed instructions than prior versions, while confirming that earlier models will be switched off. He declined to say how the new models might affect ongoing litigation but stated that no UMG or Sony copyrighted music was used to train v6.
Copyright lawsuits continue
Despite the licensed pivot, Suno still faces significant legal pressure. Universal Music Group and Sony Music are pursuing claims that Suno’s earlier models were trained on copyrighted recordings without permission, and they have pointed to Suno’s WMG and BMG deals as part of their broader argument about industry-wide AI training practices.
Additional suits have emerged in recent weeks:
A proposed class action led by singer-songwriter Jason Isbell alleges Suno violated musicians’ publicity rights by indexing artists’ names and generating songs that emulate their distinctive styles without consent.
Mexican label Gerencia 360 Music sued in late August, claiming Suno trained on regional Mexican hits to produce Spanish-language AI songs.
Canada’s SOCAN filed a federal lawsuit alleging mass copying of Canadian works to train Suno’s models without licences or compensation.
These cases underscore that even as Suno shifts to licensed data for new models, courts will still scrutinize how its past systems were built and whether outputs infringe existing works.
What this means for users and the industry
For creators, the immediate change is technical and access-based: free users now run on v6‑mini, while advanced editing and experimental features require a paid plan. For the music industry, Suno’s licensed model strategy mirrors broader efforts to align AI training with rights-holder agreements, similar to YouTube’s long-running negotiations with studios and labels.
However, the wave of publicity-rights and copyright suits suggests that licensing alone may not settle all disputes, especially where plaintiffs argue that AI systems encode and exploit artists’ identities or past recordings. As v6 becomes the default, attention will turn to how courts treat training on licensed catalogs and whether Suno’s outputs in the new regime still trigger infringement or personality claims.
