Examples

Change the image style to realistic, draw the horse in the same pose, with a black mane and a giant snowball on its nose

Draw this elephant in the same hat inside a green tractor, driving across a yellow field.

Поменяй чебурашку на крокодила Гену из мультфильма, позу и выражения лица оставь прежними

Change the image style to an oil painting; don't change the pose of the animals, but add pronounced oil painting elements - paint strokes

Kandinsky5I2IPipeline Usage Example

python

import torch
from diffusers import Kandinsky5I2IPipeline # use duffusers fork: pip install git+https://github.com/leffff/diffusers
from diffusers.utils import load_image 
# Load the pipeline
model_id = "kandinskylab/Kandinsky-5.0-I2I-Lite-sft-Diffusers"
pipe = Kandinsky5I2IPipeline.from_pretrained(model_id)

_ = pipe.to(device='cuda',dtype=torch.bfloat16)
pipe.enable_model_cpu_offload()                                               # <--- Enable CPU offloading for single GPU inference

# Edit the input image
image = load_image(
    "https://huggingface.co/kandinsky-community/kandinsky-3/resolve/main/assets/title.jpg?download=true"
)

prompt = "Change the background from a winter night scene to a bright summer day. Place the character on a sandy beach with clear blue sky, soft sunlight, and gentle waves in the distance. Replace the winter clothing with a light short-sleeved T-shirt (in soft pastel colors) and casual shorts. Ensure the character’s fur reflects warm daylight instead of cold winter tones. Add small beach details such as seashells, footprints in the sand, and a few scattered beach toys nearby. Keep the oranges in the scene, but place them naturally on the sand."
negative_prompt = ""

output = pipe(
    image=image,
    prompt=prompt,
    negative_prompt=negative_prompt,
    guidance_scale=3.5,
).image[0]
