Model Upgrade: V5 Is Now Free, New V5.5 Signature Officially Launched

Why We Upgraded

Over the past few weeks, we’ve received consistent feedback from users pointing out that pronunciation accuracy needed improvement—especially for non-English lyrics. We take this feedback seriously.

Rather than applying quick fixes, we used this as an opportunity to roll out a comprehensive upgrade across all platform models. Here’s what’s included in this update.

What’s New

V5 Studio Now Free for All Users

The V5 Studio model was previously available only to paid subscribers. Starting today, it’s free for all users.

The V5 model delivers more natural vocals, clearer separation between vocals and instruments, and better adherence to style details. If you were on the free tier, you’ll notice the difference immediately.

Introducing V5.5 Signature (Members Only)

V5.5 Signature is our new flagship model, built for users who demand the highest output quality.

Key improvements over V5 include:

• Character support — Customize vocal traits and style to match your creative vision
• More precise pronunciation — Improved accuracy for English, Japanese, Chinese, and more languages
• Richer timbre — Better dynamic range and harmonic detail in full arrangements

V5.5 Signature is a members-only model, available only in eligible paid plans.

Base Models Retired

The original Prime and Core models have been retired. They served as our foundation models at launch, but V5 now far exceeds their quality.

If your saved presets reference these models, they will automatically fall back to the V5 model.
