Suno is rolling out its new model generation in three versions and shutting down all its older models. What v6 learned from, the company won't say.
Suno built v6 with Warner Music Group, BMG, and Believe, CEO and cofounder Mikey Shulman writes in a blog post：https://suno.com/blog/introducing-v6. The models are faster, more expressive, and higher quality than their predecessors, he says.
All three models understand more musical building blocks than before, from vocals, instrumentation, and song structure to mood and references. With the rollout, Suno is pulling its older models and moving the platform entirely to the new generation. Suno's most recent release was the interim v5.5 update with a voice-cloning feature：https://the-decoder.com/suno-5-5-lets-users-sing-their-own-ai-generated-songs-with-a-personalized-voice-feature/ in March, and the last major model generation was v5 in September 2025：https://the-decoder.com/suno-releases-new-ai-music-model-v5/.

Suno v6 can change individual parts of an existing song through text input without touching the rest, for example to have just the chorus sung by a gospel choir. Users can also combine mashups from several sources in a single request, such as the vocals from one song with the drums from another and new lyrics in the style of '80s synthwave.
Users can also isolate a sample and build a new beat from it, or generate a song from a mood, a genre, or a mix of inspirations. v6 works multimodally, so users can generate a song from text, audio, images, or video. Individual lyric lines can be changed too, without regenerating the entire track. Ad
Suno calls the three partners codevelopers but gives no details on which catalogs were used or how much material went in. Fittingly, Suno had asked the US District Court in Massachusetts to keep the exact size of its training data under seal：https://the-decoder.com/ai-music-startup-suno-doubles-its-valuation-to-5-4-billion-while-fighting-major-record-labels-in-court/, arguing that competitors could infer its development approach from it.
As a next step, Suno is planning offerings built around individual artists. Artists decide for themselves whether to take part and get paid if they do, while fans get new ways to connect with them. Songs made with the partner model will be distributable through Believe and TuneCore going forward. Ad
Universal and Sony, on the other hand, remain plaintiffs in the case the RIAA coordinated in June 2024：https://the-decoder.com/music-industry-against-music-generators-could-set-major-precedent-for-the-future-of-generative-ai/. Suno asked the court to keep the exact size of its training data under seal and, in parallel, raised $400 million in June at a $5.4 billion valuation：https://the-decoder.com/ai-music-startup-suno-doubles-its-valuation-to-5-4-billion-while-fighting-major-record-labels-in-court/.
