V2: The Experimental Pioneer
Think of V2 as your mad scientist's lab. It's the perfect model for when you want to break the mold and explore truly unique sonic landscapes. While it doesn't have the polish of its successors, its raw, and sometimes gritty, output has a charm all its own.

- Key Strengths: V2 excels at producing musically interesting, if sometimes repetitive, compositions. It’s your go-to for that raw, unpolished sound.
- Limitations: The audio quality is noticeably harsher, with flatter vocals and a compressed dynamic range. It's not built for pristine pop production.
- Max Generation: 1 minute 20 seconds (extends by 40 seconds).

V3: The Versatile Innovator

A Powerful Workflow: Combine V3 and V3.5
Instead of choosing just one model, the most effective strategy is to use them together. This hybrid approach leverages the unique strengths of both V3 and V3.5.
-
Start with V3 for Creativity: Begin your project in V3. Use its flexibility with detailed style prompts to explore genre mashups and establish the core creative direction of your song.

Switch to V3.5 for Polish: Once you have a solid foundation, use the "Continue from this song" feature and switch the model to V3.5. Use it to refine the lyrics, improve vocal performance, and extend the track to its full length for a professional, finished product.
