AI imagined images. Pythonic generation of stable diffusion images and videos *!.
"just works" on Linux and macOS(M1) (and sometimes windows).
# on macOS, make sure rust is installed first
# be sure to use Python 3.10, Python 3.11 is not supported at the moment
>> pip install imaginairy
>> imagine "a scenic landscape" "a photo of a dog" "photo of a fruit bowl" "portrait photo of a freckled woman" "a bluejay"
# Make an AI video
>> aimg videogen --start-image rocket.png
Works with Nvidia GPUs. Does not work on Mac or CPU.
On Windows you'll need to install torch 2.0 first via https://pytorch.org/get-started/locally/

14.0.0
- ๐ video generation using Stable Video Diffusion
- add
--videogen
to any image generation to create a short video from the generated image - or use
aimg videogen
to generate a video from an image
- add
- ๐ SDXL (Stable Diffusion Extra Large) models are now supported.
- try
--model opendalle
or--model sdxl
- inpainting and controlnets are not yet supported for SDXL
- try
- ๐ imaginairy is now backed by the refiners library
- This was a huge rewrite which is why some features are not yet supported. On the plus side, refiners supports cutting edge features (SDXL, image prompts, etc) which will be added to imaginairy soon.
- self-attention guidance which makes details of images more accurate
- ๐ feature: larger image generations now work MUCH better and stay faithful to the same image as it looks at a smaller size.
For example
--size 720p --seed 1
and--size 1080p --seed 1
will produce the same image for SD15 - ๐ feature: loading diffusers based models now supported. Example
--model https://huggingface.co/ainz/diseny-pixar --model-architecture sd15
- ๐ feature: qrcode controlnet!
Generate images via API or web interface. Much smaller featureset compared to the command line tool.

Image Structure Control by ControlNet
Generate images guided by body poses, depth maps, canny edges, hed boundaries, or normal maps.
Openpose Control
imagine --control-image assets/indiana.jpg --control-mode openpose --caption-text openpose "photo of a polar bear"
imagine --control-image assets/lena.png --control-mode canny "photo of a woman with a hat looking at the camera"
imagine --control-image dog.jpg --control-mode hed "photo of a dalmation"
imagine --control-image fancy-living.jpg --control-mode depth "a modern living room"
imagine --control-image bird.jpg --control-mode normal "a bird"
Generates the image based on elements of the control image. Kind of similar to style transfer.
imagine --control-image pearl-girl.jpg --control-mode shuffle "a clown"
The middle image is the "shuffled" input image
Similar to instructPix2Pix (below) but works with any SD 1.5 based model.
imagine --control-image pearl-girl.jpg --control-mode edit --init-image-strength 0.01 --steps 30 --negative-prompt "" --model openjourney-v2 "make it anime" "make it at the beach"
Replaces existing details in an image. Good to use with --init-image-strength 0.2
imagine --control-image "assets/wishbone.jpg" --control-mode details "sharp focus, high-resolution" --init-image-strength 0.2 --steps 30 -w 2048 -h 2048
Colorize black and white images or re-color existing images.
The generated colors will be applied back to the original image. You can either provide a caption or allow the tool to generate one for you.
aimg colorize pearl-girl.jpg --caption "photo of a woman"
Instruction based image edits by InstructPix2Pix
Just tell imaginairy how to edit the image and it will do it for you!
Click to see shell commands
Use prompt strength to control how strong the edit is. For extra control you can combine with prompt-based masking.# enter imaginairy shell
>> aimg
๐ค๐ง > edit scenic_landscape.jpg -p "make it winter" --prompt-strength 20
๐ค๐ง > edit dog.jpg -p "make the dog red" --prompt-strength 5
๐ค๐ง > edit bowl_of_fruit.jpg -p "replace the fruit with strawberries"
๐ค๐ง > edit freckled_woman.jpg -p "make her a cyborg" --prompt-strength 13
๐ค๐ง > edit bluebird.jpg -p "make the bird wear a cowboy hat" --prompt-strength 10
๐ค๐ง > edit flower.jpg -p "make the flower out of paper origami" --arg-schedule prompt-strength[1:11:0.3] --steps 25 --compilation-anim gif
# create a comparison gif
๐ค๐ง > edit pearl_girl.jpg -p "make her wear clown makeup" --compare-gif
# create an animation showing the edit with increasing prompt strengths
๐ค๐ง > edit mona-lisa.jpg -p "make it a color professional photo headshot" --negative-prompt "old, ugly, blurry" --arg-schedule "prompt-strength[2:8:0.5]" --compilation-anim gif
๐ค๐ง > edit gg-bridge.jpg -p "make it night time" --prompt-strength 15 --steps 30 --arg-schedule prompt-strength[1:15:1] --compilation-anim gif

Prompt Based Masking by clipseg
Specify advanced text based masks using boolean logic and strength modifiers. Mask syntax:
- mask descriptions must be lowercase
- keywords (
AND
,OR
,NOT
) must be uppercase - parentheses are supported
- mask modifiers may be appended to any mask or group of masks. Example:
(dog OR cat){+5}
means that we'll select any dog or cat and then expand the size of the mask area by 5 pixels. Valid mask modifiers:{+n}
- expand mask by n pixels{-n}
- shrink mask by n pixels{*n}
- multiply mask strength. will expand mask to areas that weakly matched the mask description{/n}
- divide mask strength. will reduce mask to areas that most strongly matched the mask description. probably not useful
When writing strength modifiers keep in mind that pixel values are between 0 and 1.
>> imagine \
--init-image pearl_earring.jpg \
--mask-prompt "face AND NOT (bandana OR hair OR blue fabric){*6}" \
--mask-mode keep \
--init-image-strength .2 \
--fix-faces \
"a modern female president" "a female robot" "a female doctor" "a female firefighter"
>> imagine \
--init-image fruit-bowl.jpg \
--mask-prompt "fruit OR fruit stem{*6}" \
--mask-mode replace \
--mask-modify-original \
--init-image-strength .1 \
"a bowl of kittens" "a bowl of gold coins" "a bowl of popcorn" "a bowl of spaghetti"
Face Enhancement by CodeFormer
>> imagine "a couple smiling" --steps 40 --seed 1 --fix-faces
Upscaling by RealESRGAN
>> imagine "colorful smoke" --steps 40 --upscale
# upscale an existing image
>> aimg upscale my-image.jpg
Python Example
from imaginairy.enhancers.upscale_realesrgan import upscale_image
from PIL import Image
img = Image.open("my-image.jpg")
big_img = upscale_image(i)
>> imagine "gold coins" "a lush forest" "piles of old books" leaves --tile
imagine --tile-x -w 1024 -h 512 "360 degree equirectangular panorama photograph of the desert" --upscale
Use depth maps for amazing "translations" of existing images.
>> imagine --init-image girl_with_a_pearl_earring_large.jpg --init-image-strength 0.05 "professional headshot photo of a woman with a pearl earring" -r 4 -w 1024 -h 1024 --steps 50
Given a starting image, one can generate it's "surroundings".
Example:
imagine --init-image pearl-earring.jpg --init-image-strength 0 --outpaint all250,up0,down600 "woman standing"
Click to see shell command
imagine "valley, fairytale treehouse village covered, , matte painting, highly detailed, dynamic lighting, cinematic, realism, realistic, photo real, sunset, detailed, high contrast, denoised, centered, michael whelan" --steps 60 --seed 1 --arg-schedule model[sd14,sd15,sd20,sd21,openjourney-v1,openjourney-v2] --arg-schedule "caption-text[sd14,sd15,sd20,sd21,openjourney-v1,openjourney-v2]"
You can use {}
to randomly pull values from lists. A list of values separated by |
and enclosed in { }
will be randomly drawn from in a non-repeating fashion. Values that are surrounded by _ _
will
pull from a phrase list of the same name. Folders containing .txt phraselist files may be specified via
--prompt_library_path
. The option may be specified multiple times. Built-in categories:
3d-term, adj-architecture, adj-beauty, adj-detailed, adj-emotion, adj-general, adj-horror, animal, art-scene, art-movement,
art-site, artist, artist-botanical, artist-surreal, aspect-ratio, bird, body-of-water, body-pose, camera-brand,
camera-model, color, cosmic-galaxy, cosmic-nebula, cosmic-star, cosmic-term, desktop-background, dinosaur, eyecolor, f-stop,
fantasy-creature, fantasy-setting, fish, flower, focal-length, food, fruit, games, gen-modifier, hair, hd,
iso-stop, landscape-type, national-park, nationality, neg-weight, noun-beauty, noun-fantasy, noun-general,
noun-horror, occupation, painting-style, photo-term, pop-culture, pop-location, punk-style, quantity, rpg-item, scenario-desc,
skin-color, spaceship, style, tree-species, trippy, world-heritage-site
Examples:
imagine "a {lime|blue|silver|aqua} colored dog" -r 4 --seed 0
(note that it generates a dog of each color without repetition)
imagine "a {_color_} dog" -r 4 --seed 0
will generate four, different colored dogs. The colors will be pulled from an included
phraselist of colors.
imagine "a {_spaceship_|_fruit_|hot air balloon}. low-poly" -r 4 --seed 0
will generate images of spaceships or fruits or a hot air balloon
Python example
from imaginairy.enhancers.prompt_expansion import expand_prompts
my_prompt = "a giant {_animal_}"
expanded_prompts = expand_prompts(n=10, prompt_text=my_prompt, prompt_library_paths=["./prompts"])

- 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)
- Prompt metadata saved into image file metadata
- Have AI generate captions for images
aimg describe <filename-or-url>
- Interactive prompt: just run
aimg
