## Inference Requirements and Model Introduction
+ Resolution: Width and height must be between `512px` and `2048px`, divisible by `32`, and ensure the maximum number of
pixels does not exceed `2^21` px.
+ Precision: BF16 / FP32 (FP16 is not supported as it will cause overflow resulting in completely black images)
Using `BF16` precision with `batchsize=4` for testing, the memory usage is shown in the table below:
| Resolution | enable_model_cpu_offload OFF | enable_model_cpu_offload ON | enable_model_cpu_offload ON Text Encoder 4bit |
|-------------|------------------------------|-----------------------------|-----------------------------------------------------|
| 512 * 512 | 33GB | 20GB | 13G |
| 1280 * 720 | 35GB | 20GB | 13G |
| 1024 * 1024 | 35GB | 20GB | 13G |
| 1920 * 1280 | 39GB | 20GB | 14G |
| 2048 * 2048 | 43GB | 21GB | 14G |
## Quick Start
First, ensure you install the `diffusers` library from source.
```shell
pip install git+https://github.com/huggingface/diffusers.git
cd diffusers
pip install -e .
```
Then, run the following code:
```python
from diffusers import CogView4Pipeline
pipe = CogView4Pipeline.from_pretrained("THUDM/CogView4-6B", torch_dtype=torch.bfloat16)
# Open it for reduce GPU memory usage
pipe.enable_model_cpu_offload()
pipe.vae.enable_slicing()
pipe.vae.enable_tiling()
prompt = "A vibrant cherry red sports car sits proudly under the gleaming sun, its polished exterior smooth and flawless, casting a mirror-like reflection. The car features a low, aerodynamic body, angular headlights that gaze forward like predatory eyes, and a set of black, high-gloss racing rims that contrast starkly with the red. A subtle hint of chrome embellishes the grille and exhaust, while the tinted windows suggest a luxurious and private interior. The scene conveys a sense of speed and elegance, the car appearing as if it's about to burst into a sprint along a coastal road, with the ocean's azure waves crashing in the background."
image = pipe(
prompt=prompt,
guidance_scale=3.5,
num_images_per_prompt=1,
num_inference_steps=50,
width=1024,
height=1024,
).images[0]
image.save("cogview4.png")
```
