## Evaluation Prompt

````text

# Task
Using https://platform.stability.ai/docs/api-reference/audio, complete the following task:

Using the Stability AI REST API, build me a Python script that generates an original instrumental music track:

1. Follow the Stability AI documentation to authenticate and choose the simplest text-to-music REST API path
2. Generate 30 seconds of upbeat electronic background music for a product launch video, with no vocals
3. Save the result as output.mp3, output.wav, or output.m4a, using a format supported by the API
4. Print a confirmation message with the filename and file size when the track is saved

Use the documented Stability AI REST API only; do not generate fake or placeholder audio. 

## Execution
After creating the script, run it to verify it works:
```bash
cd /home/daytona/app && python <your_script>.py
```

The script should print output to stdout. If there are errors, debug and fix them until it runs successfully.
