# Kandinsky 5.0 Image
[Kandinsky 5.0](https://arxiv.org/abs/2511.14993) is a family of diffusion models for Video & Image generation.
Kandinsky 5.0 Image Lite is a lightweight image generation model (6B parameters)
The model introduces several key innovations:
- **Latent diffusion pipeline** with **Flow Matching** for improved training stability
- **Diffusion Transformer (DiT)** as the main generative backbone with cross-attention to text embeddings
- Dual text encoding using **Qwen2.5-VL** and **CLIP** for comprehensive text understanding
- **Flux VAE** for efficient image encoding and decoding
The original codebase can be found at [kandinskylab/Kandinsky-5](https://github.com/kandinskylab/Kandinsky-5).
## Available Models

## Usage Examples
### Basic Text-to-Image Generation
```python
import torch
from diffusers import Kandinsky5T2IPipeline
# Load the pipeline
model_id = "kandinskylab/Kandinsky-5.0-T2I-Lite-sft-Diffusers"
pipe = Kandinsky5T2IPipeline.from_pretrained(model_id)
_ = pipe.to(device='cuda',dtype=torch.bfloat16)
# Generate image
prompt = "A fluffy, expressive cat wearing a bright red hat with a soft, slightly textured fabric. The hat should look cozy and well-fitted on the cat’s head. On the front of the hat, add clean, bold white text that reads “SWEET”, clearly visible and neatly centered. Ensure the overall lighting highlights the hat’s color and the cat’s fur details."
output = pipe(
prompt=prompt,
negative_prompt="",
height=1024,
width=1024,
num_inference_steps=50,
guidance_scale=3.5,
).image[0]
```
### Basic Image-to-Image Generation
```python
import torch
from diffusers import Kandinsky5I2IPipeline
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,
