Suno AI, the artificial intelligence music generator that has received both widespread notice and legal issues, has released its most recent upgrade, v4.5. This updated version has a number of features that allow users to construct richer, more complex, and lengthier musical compositions from simple text prompts.
Suno AI v4.5, which includes enhancements in vocal quality, genre blending, prompt understanding, and song duration, intends to make AI-powered music creation more accessible and powerful for both new and experienced users.
Vocal and Genre Enhancements Drive Suno AI v4.5
One of the most notable advancements in v4.5 is the enhanced capability in generating vocals. Suno says that this new update allows users to make everything, from soft and personal vocal performances to strong deliveries that include vibrato, along with a wider range of emotional expression. This suggests a significant step forward in the realism and emotional depth that can be achieved in AI-generated singing.
The new version also boasts greater flexibility in musical styles. Suno highlights the ability to seamlessly blend seemingly disparate genres, providing examples like mixing punk rock with neo-soul or EDM with folk. The company claims that v4.5 can produce results that sound smooth and natural even when combining such diverse musical elements, opening up new avenues for creative exploration.
Suno AI v4.5 also demonstrates an improved understanding of user prompts, particularly those that include more complex or nuanced descriptions. The AI can now better interpret and translate descriptions such as “uplifting nostalgic tones” or “melodic whistling,” reflecting these subtleties more clearly in the generated music.

To further aid users in crafting effective prompts, v4.5 includes a new prompt enhancement helper. This feature guides users in creating more detailed and creative instructions, helping them to transform simple ideas into more fully realized musical concepts.
Beyond sound quality and genre flexibility, v4.5 makes practical enhancements to the music-making process. The maximum song duration has been raised from four to eight minutes, enabling the development of longer musical works. Suno also claims an overall increase in music generation speed, though no precise metrics were supplied.
Suno AI Advances Amidst Competition and Copyright Scrutiny
For users who enjoy remixing and reinterpreting existing songs, v4.5 expands the functionality of the platform’s Covers and Personas features. This enhancement allows for more creative “genre switching,” enabling users to, for example, transform a rock song into a house remix with greater ease and potentially more compelling results.
Suno emphasizes that v4.5 delivers better overall sound quality with more balanced mixes. The update reportedly addresses issues such as audio degradation and unwanted “shimmer effects,” ensuring that songs maintain a more consistent and stable sound quality from beginning to end, even in longer compositions.

It is important to note that the v4.5 model is currently exclusive to Suno’s paid subscribers, with Pro tier plans starting at $8 per month. Free users continue to have access to the older v4.0 model with a limited number of total song generations, as well as an even earlier v3.5 model with a daily creation cap.
Suno AI’s latest update arrives at a time of increasing competition in the AI music generation space, with companies like Splice making strategic acquisitions to bolster their AI music creation capabilities.
Simultaneously, Suno faces ongoing legal challenges from the music industry regarding copyright concerns related to the training data used for its AI models. Despite these controversies, Suno has also formed partnerships, such as its integration with Amazon’s next-generation Alexa.
