Kandinsky 5.0 is a family of diffusion models for video and image generation.
Kandinsky 5.0 Image Lite is a lightweight text-to-image (T2I) generation model with 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).

## Examples
## Kandinsky5T2IPipeline Usage Example
```python
import torch
from diffusers import Kandinsky5T2IPipeline
# Load the pipeline
model_id = "kandinskylab/Kandinsky-5.0-T2I-Lite-pretrain-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]
```
