## Inference Requirements and Model Overview |
|
|
|
This model is the DiT version of CogView3, a text-to-image generation model, supporting image generation from 512 to 2048px. |
|
|
|
+ Resolution: Width and height must meet the range from 512px to 2048px and must be divisible by 32. |
|
+ Inference Speed: 1s / step (tested on A100) |
|
+ Precision: BF16 / FP32 (FP16 is not supported, as it leads to overflow causing black images) |
|
|
|
## Memory Consumption |
|
|
|
We tested memory consumption at several common resolutions on A100 devices, `batchsize=1, BF16`, as shown in the table below: |

|-------------|------------------------------|-----------------------------| |
|
| 512 * 512 | 19GB | 11GB | |
|
| 720 * 480 | 20GB | 11GB | |
|
| 1024 * 1024 | 23GB | 11GB | |
|
| 1280 * 720 | 24GB | 11GB | |
|
| 2048 * 2048 | 25GB | 11GB | |
|

|
## Quick Start |
|
|
|
First, ensure the `diffusers` library is installed **from source**. |
|
``` |
|
pip install git+https://github.com/huggingface/diffusers.git |
|
``` |
|
|
|
Then, run the following code: |
|
|
|
```python |
|
from diffusers import CogView3PlusPipeline |
|
import torch |
|
|
|
pipe = CogView3PlusPipeline.from_pretrained("THUDM/CogView3-Plus-3B", torch_dtype=torch.float16).to("cuda") |
|
|
|
# Enable it to 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." |
