# Features

### Models

Call models such as GPT-4, ElevenLabs or Stable Diffusion in a single line. 

```
[prompt.generate_background]
model_name = stable-diffusion-xl
message = Background image. Light colors. {{user_input}}
```

PromptSpace is constantly adding new models and will support self-hosted models soon. Email <nico@promptspace.app> to request a model you need to create your UX.

### API Keys

PromptSpace provides the API keys--no more subscribing to waitlists.

### UI

Choose how to display the output of a block to the user.

```
display_option = image / video / markdown
```

The output of each block of displayed to the user as text by default. Hide the output of intermediate blocks.

```
display = False
```

### Output Validation

Assets that the output of a block conforms to a format.

```
output_type = json / ini / nlp
```

### Dependencies

Use the most popular Python dependencies including LangChain, Beautiful Soup and MoviePy without `requirements.txt` or reading the docs. PSL only exposes features useful for GenAI apps.

```
[prompt.read_page]
model_name = bsoup
description.url = Please paste a Wikipedia url:
url = {{url}}
output_type = nlp
display = False 

[prompt.question]
description.question = What would you like to ask?
message = {{response.read_page.ask(question)}}

```

### Concurrency

PromptSpace implements the job queues so you can focus on the UX of a single user.
