Extend Music API FAQ
What's the difference between custom mode and inherit mode?
Inherit mode (custom_mode: false) automatically continues your music using the source track's characteristics - perfect for seamless extensions. Custom mode (custom_mode: true) lets you specify new parameters like prompt, style, and title to create variations or change direction while extending.
How do I control where the extension starts?
Use the continue_at parameter to specify the starting point in seconds. For example, continue_at: 30 starts extending from 30 seconds into your source track. This is perfect for creating loops, extending specific sections, or continuing from precise musical moments.
What are the maximum extension lengths for different models?
Extension length depends on the model version: V4 supports extensions up to 4 minutes total, while V4.5, V4.5PLUS, V5, and V5.5 support up to 8 minutes total. Choose your model based on desired output length and quality requirements.
Can I extend music multiple times to create longer tracks?
Yes! You can chain multiple extensions by using the output of one extension as the source audio for the next. This allows you to create tracks longer than the 8-minute maximum per extension, perfect for long-form content.
How do I maintain style consistency when extending music?
Use inherit mode to automatically maintain the source track's style, or in custom mode, use high style_weight values (0.8-1.0) and avoid negative_tags that would exclude the original style characteristics. The API is designed to maintain musical coherence across extensions.
