Inputs (24)
| Name | Type | Default | Description |
|---|---|---|---|
| prompt | STRING | A calm and relaxing piano track with soft melodies | A description of the desired audio content. Optional. - Custom mode (`custom_mode=true`): When provided, the prompt is used strictly as lyrics and sung in the generated track. Character limits by model: - V4: Maximum 3000 characters - V4_5, V4_5PLUS, V4_5ALL, V5_5, V5: Maximum 5000 characters - Non-custom mode (`custom_mode=false`): When provided, the prompt serves as the core idea. Lyrics are generated automatically based on it and do not strictly match the input. Maximum 3000 characters. `prompt` is not required. In non-custom mode, provide at least one of `image_urls`, `video_urls`, `audio_urls`, `style`, or `lyrics`. In custom mode, provide at least one of `style`, `lyrics`, or `negative_tags`. Generation is rejected if all related inputs are empty. |
| custom_mode | BOOLEAN | true | Determines whether advanced parameter customization is enabled. - If `true`: Allows detailed control - If `false`: Simplified mode |
| instrumental | BOOLEAN | true | Determines whether the audio should be instrumental (no lyrics). - In Custom Mode (`custom_mode: true`): - If `true`: Only `style` and `title` are required. - If `false`: `style`, `title`, and `prompt` are required (`prompt` is used as the exact lyrics). - In Non-custom Mode (`custom_mode: false`): - If `true`: Only `style` and `prompt` are required. - If `false`: `style`, `prompt`, and `lyrics` are required (`lyrics` is used as a lyrics attachment and can be used together with the audio description in `prompt`). |
| styleopt | STRING | Classical | Music style specification for the generated audio. - Character limits by model: - **V4** (Discontinued): Maximum 200 characters - **V4_5 and V4_5PLUS** (Discontinued): Maximum 1000 characters - **V4_5ALL** (Discontinued): Maximum 1000 characters - **V5_5 and V5** (Discontinued): Maximum 1000 characters - **V6, V6_MINI, and V6_WILD**: Maximum 1000 characters - Common examples: Jazz, Classical, Electronic, Pop, Rock, Hip-hop, etc. |

| negative_tagsopt | STRING | Heavy Metal, Upbeat Drums | Music styles or traits to exclude from the generated audio. Optional. Use to avoid specific styles. |
| vocal_genderopt | COMBO | m | Vocal gender preference. Optional. Use `m` for male and `f` for female. This parameter is only effective when `custom_mode` is true. In practice, it only increases probability and cannot guarantee male/female voice instructions are followed. |
| style_weightopt | FLOAT | 0.650–1 | Only available when Custom Mode (`custom_mode: true`) is enabled. Strength of adherence to the specified style. Optional. Range 0–1, up to 2 decimal places. |
| weirdness_constraintopt | FLOAT | 0.650–1 | Only available when Custom Mode (`custom_mode: true`) is enabled. Controls experimental/creative deviation. Optional. Range 0–1, up to 2 decimal places. |
| audio_weightopt | FLOAT | 0.650–1 | Only available when Custom Mode (`custom_mode: true`) is enabled. Relative weight of audio features. Optional. Range 0–1, up to 2 decimal places. - `audio_weight` is not supported when there are no vocals |
| persona_idopt | STRING | persona_123 | Persona ID or Voice ID to apply to the generated music. Optional. Use this to apply a specific persona style to your music generation. To generate a Persona ID, use the [Generate Persona](https://docs.kie.ai/suno-api/generate-persona) endpoint to create a personalized music Persona based on generated music. To generate a Voice ID, use the [Generate Voice](https://docs.kie.ai/suno-api/suno-voice-generate) endpoint. |
| persona_modelopt | COMBO | style_persona | Persona model. Only available for V5 (Discontinued), V5.5 (Discontinued), V6, V6_MINI, and V6_WILD. |

| image_urlsopt | IMAGE | — | |
| varietyopt | FLOAT | 1.000–4 | Only available when Custom Mode (`custom_mode: true`) is enabled. Controls the diversity and stylistic variation of generated results. Optional. Range 0–4, integer, default 1. - **`0`**: off (exact style) — fully off, strictly the same style - **`1`**: normal (balanced variety) — default, balances stability and diversity - **`2`**: high (distinct styles) — produces results with clearly different styles - **`3`**: extra (bold exploration) — higher variation, encourages bold exploration of different styles - **`4`**: max (unreasonably varied) — maximum diversity; results may differ in style very significantly |
| lyricsopt | STRING | Lyrics for the generated audio. Optional. - V6: Maximum 5000 characters. - When `custom_mode=true`, `lyrics` is used as lyrics first; if `lyrics` is not provided, `prompt` is used as lyrics. - When `custom_mode=false`, `lyrics` is used as a lyrics attachment and can be used together with the audio description in `prompt`. | |
