# Music Models

Two AI models are available for Music Generation in Qolaba — each with different output length, supported formats, configuration options, and credit costs. Choosing the right model depends on whether you need a short clip or a full-length song, and how much control you want over the output structure.

#### Model Overview

| Model             | Provider | Duration     | Credits | Format   | Lyrics |

| **Lyria 3 Pro** ⭐ | Google   | Full-length  | 21      | MP3, WAV | ✓      |

#### Configuration Options

**Instrumental Only**

Toggle on to generate music without vocals. Available across all models — useful for background tracks, soundscapes, and any content where vocals are not needed.

**Format Selection**

| Format  | File Size | Best For                                       |
| ------- | --------- | ---------------------------------------------- |
| **MP3** | Smaller   | Sharing, social media, web use                 |
| **WAV** | Larger    | High-fidelity editing, professional production |

{% hint style="info" %}
WAV is only available on Lyria 3 Pro. All other models output MP3 only.
{% endhint %}

**Negative Prompt**

Describe what to exclude from the generation — instruments, styles, tempos, or moods you do not want. 

**Examples:**

```
No drums, no distortion, no fast tempo.
```

```
Avoid brass instruments, no vocals, no reverb.
```

**Seed**

Enter a number to make your generation reproducible. Using the same prompt, model, and seed number produces the same output every time — useful for iterating on a specific result or sharing a configuration with a collaborator.

**Magic Prompt**

One-click AI enhancement that rewrites your prompt into a more detailed, model-optimized version before generation.

* **Cost:** \~0.05 credits
* **Best for:** Short or underdeveloped prompts
