# Introduction to Workflows

*Workflows* let you chain together multiple jobs into a single convenient call to Prodia's API. This helps minimise latency, reduce code complexity, and save bandwidth.

## Use Cases

Workflows are great for:

- Generating an image and then checking whether it's safe for work
- Creating an initial generation with one model then transforming it with another
- Using an image model with better prompt following and then using it as the basis for a video generation

## Example

Workflows are themselves jobs like any other on Prodia's v2 platform.

Here's an example of a workflow that only calls one job:

```json
{
  "type": "workflow.serial.v1",
  "jobs": [
    {
      "type": "inference.flux-fast.schnell.txt2img.v2",
      "config": {
        "prompt": "A beautiful image of a cat"
      }
    }
  ]
}
```

This job can be expanded to also do a moderation check as well:

```json
{
  "type": "workflow.serial.v1",
  "jobs": [
    {
      "type": "inference.flux-fast.schnell.txt2img.v2",
      "config": {
        "prompt": "A beautiful image of a cat"
      }
    },
    {
      "type": "workflow.moderate.v1",
      "config": {
        "threshold": 0.95
      }
    }
  ]
}
```
