# Krea 2 Turbo SDNQ Dynamic INT4
*Left: original bf16 · Right: this SDNQ int4 model (same prompt and seed).*
This is an int4 quantized version of [krea/Krea-2-Turbo](https://huggingface.co/krea/Krea-2-Turbo) using [SDNQ](https://github.com/Disty0/sdnq) (SD.Next Quantization) with the dynamic option and Hadamard Rotation.
Note: You need SDNQ v0.2.0 or v0.2.2 and above (v0.2.1 is incompatible)
## Usage
You can find ready-to-use scripts in the [diffusers-recipes](https://github.com/asomoza/diffusers-recipes/blob/main/models/krea2_turbo/README.md) repository.
## Sample image
The quantized (right) image above was generated with the following prompt and settings (seed `7`):
```python
import sdnq # register the SDNQ backend before loading
import torch
from diffusers import DiffusionPipeline
pipe = DiffusionPipeline.from_pretrained("OzzyGT/Krea_2_Turbo_sdnq_dynamic_4bit", torch_dtype=torch.bfloat16)
pipe.to("cuda")
prompt = (
"A cozy corner bookstore-cafe on a rainy evening, cinematic wide shot. "
'A large hand-lettered chalkboard sign in the window reads "FRESH COFFEE & OLD BOOKS" '
"and below it in smaller chalk letters \"open 'til late\". "
"Warm golden light spills onto wet cobblestones that mirror pink and blue neon reflections. "
"Inside, tall mahogany shelves are packed with hundreds of colorful book spines with tiny legible titles, "
"a barista in a striped apron pours delicate latte art, steam curling upward, "
"a tabby cat sleeps on a windowsill beside a stack of paperbacks. "
"Intricate detail, sharp focus, shallow depth of field, photorealistic, rich color grading."
)
