# provider-fal (fal.ai Image Generation Example)
|
|
|
|
You can run this example with:
|
|
|
|
```bash
|
|
npx promptfoo@latest init --example provider-fal
|
|
cd provider-fal
|
|
```
|
|
|
|
Demonstrates how to evaluate and compare image generation models using promptfoo.
|
|
|
|
## Setup
|
|
|
|
1. **Get your API key** from [fal.ai dashboard](https://fal.ai/dashboard/keys)
|
|
2. **Set environment variable**:
|
|
```bash
|
|
export FAL_KEY=your-fal-key-here
|
|
```
|
|
3. **Install client**:
|
|
```bash
|
|
npm install @fal-ai/client
|
|
```
|
|
4. **Run the evaluation**:
|
|
```bash
|
|
promptfoo eval
|
|
```
|
|
|
|
## What This Example Shows
|
|
|
|
- **Model comparison**: Two different fal.ai models side-by-side
|
|
- **Creative prompts**: 7 test cases with artistic styles
|
|
- **Reproducible results**: Fixed seeds for consistent outputs
|
|
- **Configuration options**: Different settings per model
|
|
|
|
## Example Output
|
|
|
|
The evaluation generates a comparison table showing:
|
|
|
|
- Model performance across different prompts
|
|
- Generated images in markdown format
|
|
- Execution time and caching behavior
|
|
|
|
## View Results
|
|
|
|
```bash
|
|
promptfoo view
|
|
```
|
|
|
|
Opens the web interface to browse generated images and compare model outputs.
|
|
|
|
## Customize the Example
|
|
|
|
Edit `promptfooconfig.yaml` to:
|
|
|
|
- Try different models from [fal.ai/models](https://fal.ai/models)
|
|
- Add your own prompts
|
|
- Adjust model parameters
|
|
- Add assertions to test output quality
|
|
- Route SDK requests through a proxy with `config.client.proxyUrl` when your environment requires it
|
|
