# ImaginAIry 🤖🧠

AI imagined images. Pythonic generation of stable diffusion images.

"just works" on Linux and OSX(M1).

## Examples
### Multiple Prompts
```bash
>> pip install imaginairy
>> imagine "a scenic landscape" "a photo of a dog" "photo of a fruit bowl" "portrait photo of a freckled woman"
🤖🧠 received 4 prompt(s) and will repeat them 1 times to create 4 images.

## Features
 
 - It makes images from text descriptions! 🎉
 - Generate images either in code or from command line.
 - It just works. Proper requirements are installed. model weights are automatically downloaded. No huggingface account needed. 
    (if you have the right hardware... and aren't on windows)
 - Noisy logs are gone (which was surprisingly hard to accomplish)
 - WeightedPrompts let you smash together separate prompts (cat-dog)
 - Tile Mode creates tileable images
 - Prompt metadata saved into image file metadata

## How To

```python
from imaginairy import imagine_images, imagine_image_files, ImaginePrompt, WeightedPrompt

prompts = [
    ImaginePrompt("a scenic landscape", seed=1),
    ImaginePrompt("a bowl of fruit"),
    ImaginePrompt([
       WeightedPrompt("cat", weight=1),
       WeightedPrompt("dog", weight=1),
    ])
]
for result in imagine_images(prompts):
    # do something
    result.save("my_image.jpg")
    
# or

imagine_image_files(prompts, outdir="./my-art")

```

## Requirements
- ~10 gb space for models to download
- A decent computer with either a CUDA supported graphics card or M1 processor.

## Improvements from CompVis
 - img2img actually does # of steps you specify
 - performance optimizations

## Models Used
 - CLIP - https://openai.com/blog/clip/
 - LDM - Latent Diffusion
 - Stable Diffusion 
   - https://github.com/CompVis/stable-diffusion
   - https://huggingface.co/CompVis/stable-diffusion-v1-4
   - https://laion.ai/blog/laion-5b/

## Not Supported
 - a web interface. this is a python library
