- Suno's new free v4.5-All music model offers dramatically improved speed, sound, and vocal quality
- v4.5-All brings pro-level music creation to everyday users with no subscription required
- The move comes as competition among AI music toolmakers rapidly heats up
Suno’s latest move in the AI music race opens the doors to a version of its most powerful model to anyone. The company has replaced Suno v3.5 on its free tier with the far faster and more advanced v4.5-All.
Suno v4.5-All is a slightly less powerful variant of the Suno 4.5 model released earlier this year. Like its sibling, v4.5-all can produce a full-length song, complete with lyrics, vocals, instrumentation, and post-production polish.
However, while Suno's paid tiers have always offered the best performance, the newly released v4.5-All bridges that gap by dropping one of its most sophisticated models into the free tier. It’s a major shift, not just in quality but also in access.
The new public version of the model is optimized for efficiency but still deeply capable of making professional-seeming songs across genres and vocal types. Suno claims it handles tone shifts better, understands prompts more fully, and still comes up with the song more quickly than v3.5 ever could.
In other words, it makes fewer mistakes, finishes faster, and delivers something you might actually want to share, without you needing to pay.
The improvements from v3.5 are immediate and obvious. Where earlier free versions sometimes struggled with genre fidelity or fell flat in vocal delivery, v4.5-All has a new level of musical nuance. Prompts now produce tracks with smoother transitions, tighter structure, and emotion.

There are still limitations and obstacles with v4.5-All, of course. Just because it's more expressive than its predecessor doesn't mean it won't stumble when it comes to things like long-form lyric coherence, digitally flat sounds, or synthetic-seeming singing. But for most users, those imperfections are easy to forgive.
All of this comes at an interesting moment for the AI music space. Everyone from YouTube to Google's Music Sandbox, and possibly even OpenAI, is keen to get in on the space, despite complaints about a flood of mislabeled AI songs, some falsely advertised as made by real people.
But most AI musicmakers still keep their higher-end tools behind paywalls, limiting what users can really do without financial commitment. Suno’s choice to elevate the free tier might put pressure on those competitors to open their doors a little wider. It also risks undermining its own subscription model, unless the upcoming v5 teased by the company represents an even larger leap that justifies the price tag. Plus, Suno and other AI music platforms are under a cloud of industry scrutiny and legal battles.
By giving people tools that actually sound good, even in the free tier, Suno is betting that what the world really needs right now isn’t more content, but more people confident enough to make it. Ultimately, it's a signpost for future AI tools, offering enough power and fine control to make all kinds of media that match what's in people's heads, even if it might violate copyright laws.
