AI music platform Suno has launched version 4.5 of its music generator, bringing several major upgrades for users creating songs with artificial intelligence. The update arrives as Suno continues to face growing legal pressure over its AI training methods, but the company shows no signs of slowing down.
The new update focuses on improving the realism and emotional range of its vocals. According to Suno, users can now create “everything from delicate, intimate performances to powerful deliveries with vibrato.” These improvements aim to bring a more natural and expressive sound to AI vocals, making them feel more like a human performance.
Version 4.5 also introduces more accurate interpretation of user prompts. Suno says the model now “better understands and translates your descriptions: capturing the details, moods, and instruments you specify… Now, both emotional nuances and technical music elements are better reflected in your song.” These updates make music creation even easier – a task that the Suno boss claims is unenjoyable for many artists, which is one of the reasons the company exists.
Another key upgrade is the extended track length. Previously limited to four minutes, users can now create tracks up to eight minutes long, offering more room for structure, storytelling, or ambient compositions. Suno also claims that the generation speed has improved, although it hasn’t shared any specific figures.
The update includes a prompt-enhancement helper that guides users on how to write better descriptions to get more accurate results. This tool helps users shape their ideas into clearer instructions, improving the creative process.
In addition, the v4.5 release enhances Suno’s Covers and Personas features. These tools allow users to switch genres on existing tracks – for example, turning a rock song into a house remix. Alongside this, Suno promises better audio quality, with more balanced mixes and fewer glitches like shimmer or dropouts. “Your songs better maintain consistent sound quality from beginning to end, even in longer compositions,” the company said.
However, these upgrades are only available to paying users. Suno’s Pro plan starts at $8 per month. Free users are restricted to version 4.0, with a cap of 20 total creations, and 10 daily uses of the older 3.5 model.
Suno continues to face legal scrutiny over its AI training methods. It was sued by GEMA in January and again in June by major record labels for allegedly using copyrighted recordings without permission – claims that Suno and fellow AI firm Udio appeared to acknowledge in court. Yet, this hasn’t stopped the company from striking big partnerships, including a February deal with Amazon to integrate its tools into the next-gen Alexa, showing that demand for AI music tools remains high despite ongoing copyright concerns.
Suno’s latest update highlights how fast AI music tools are developing. With extended track lengths, improved vocals, and smarter prompts, music creation is becoming quicker and more accessible. But as these tools evolve, so do the questions around originality and creative ownership. The distinction between AI-assisted and AI-generated music continues to shift, prompting debate within the music community and beyond.
Governments are beginning to explore regulation, while industry attitudes remain mixed – some see these tools as useful creative aids, others as a threat to artistic integrity. As policies and perspectives continue to develop, independent artists will need to navigate both the opportunities and challenges AI brings to music-making.
