# Conditional image generation
[[open-in-colab]]
Conditional image generation allows you to generate images from a text prompt. The text is converted into embeddings which are used to condition the model to generate an image from noise.
The [`DiffusionPipeline`] is the easiest way to use a pre-trained diffusion system for inference.
Start by creating an instance of [`DiffusionPipeline`] and specify which pipeline [checkpoint](https://huggingface.co/models?library=diffusers&sort=downloads) you would like to download.
In this guide, you'll use [`DiffusionPipeline`] for text-to-image generation with [Latent Diffusion](https://huggingface.co/CompVis/ldm-text2im-large-256):
```python
>>> from diffusers import DiffusionPipeline
>>> generator = DiffusionPipeline.from_pretrained("CompVis/ldm-text2im-large-256")
```
The [`DiffusionPipeline`] downloads and caches all modeling, tokenization, and scheduling components.
Because the model consists of roughly 1.4 billion parameters, we strongly recommend running it on a GPU.
You can move the generator object to a GPU, just like you would in PyTorch:
```python
>>> generator.to("cuda")
```
Now you can use the `generator` on your text prompt:
```python
>>> image = generator("An image of a squirrel in Picasso style").images[0]
```
The output is by default wrapped into a [`PIL.Image`](https://pillow.readthedocs.io/en/stable/reference/Image.html?highlight=image#the-image-class) object.
You can save the image by calling:
```python
>>> image.save("image_of_squirrel_painting.png")
```
Try out the Spaces below, and feel free to play around with the guidance scale parameter to see how it affects the image quality!
