# Autoregressive Image Generation without Vector Quantization
|
| 7 |
+
|
| 8 |
+
## About
|
| 9 |
+
This model (MAR) introduces a novel approach to autoregressive image generation by eliminating the need for vector quantization.
|
| 10 |
+
Instead of relying on discrete tokens, the model operates in a continuous-valued space using a diffusion process to model the per-token probability distribution.
|
| 11 |
+
By employing a Diffusion Loss function, the model achieves efficient and high-quality image generation while benefiting from the speed advantages of autoregressive sequence modeling.
|
| 12 |
+
This approach simplifies the generation process, making it applicable to broader continuous-valued domains beyond just image synthesis.
|
| 13 |
+
It is based on [this paper](https://arxiv.org/abs/2406.11838)
|
| 14 |
+
|
| 15 |
+
## Usage:
|
| 16 |
+
You can easily load it through the Hugging Face `DiffusionPipeline` and optionally customize various parameters such as the model type, number of steps, and class labels.
|
| 17 |
+
|
| 18 |
+
```python
|
| 19 |
+
from diffusers import DiffusionPipeline
|
| 20 |
+
|
| 21 |
+
# load the pretrained model
|
| 22 |
+
pipeline = DiffusionPipeline.from_pretrained("jadechoghari/mar", trust_remote_code=True, custom_pipeline="jadechoghari/mar")
|
| 23 |
+
|
| 24 |
+
# generate an image with the model
|
| 25 |
+
generated_image = pipeline(
|
| 26 |
+
model_type="mar_base", # choose from 'mar_base', 'mar_large', or 'mar_huge'
|
| 27 |
+
seed=42, # set a seed for reproducibility
|
| 28 |
+
num_ar_steps=64, # number of autoregressive steps
|
| 29 |
+
class_labels=[207, 360, 388], # provide valid ImageNet class labels
|
| 30 |
+
cfg_scale=4, # classifier-free guidance scale
|
| 31 |
+
output_dir="./images", # directory to save generated images
|
| 32 |
+
)
|
| 33 |
+
|
| 34 |
+
# display the generated image
|
| 35 |
+
generated_image.show()
|
| 36 |
+
```

|
| 41 |
+
|
| 42 |
+
This code loads the model, configures it for image generation, and saves the output to a specified directory.
|
| 43 |
+
|
| 44 |
+
We offer three pre-trained MAR models in `safetensors` format:
|
| 45 |
+
- `mar-base.safetensors`
|
| 46 |
+
- `mar-large.safetensors`
|
| 47 |
+
- `mar-huge.safetensors`

This is a Hugging Face Diffusers/GPU implementation of the paper [Autoregressive Image Generation without Vector Quantization](https://arxiv.org/abs/2406.11838)
|
| 55 |
+
|
| 56 |
+
The Official PyTorch Implementation is released in [this repository](https://github.com/LTH14/mar)
