+# BK-SDM-v2 Model Card
+
+BK-SDM-{[**v2-Base**](https://huggingface.co/nota-ai/bk-sdm-v2-base), [**v2-Small**](https://huggingface.co/nota-ai/bk-sdm-v2-small), [**v2-Tiny**](https://huggingface.co/nota-ai/bk-sdm-v2-tiny)} are obtained by compressing [SD-v2.1-base](https://huggingface.co/stabilityai/stable-diffusion-2-1-base). 
+- Block-removed Knowledge-distilled Stable Diffusion Models (BK-SDMs) are developed for efficient text-to-image (T2I) synthesis:
+  - Certain residual & attention blocks are eliminated from the U-Net of SD.
+  - Despite the use of very limited data, distillation retraining remains surprisingly effective.
+- Resources for more information: [Paper](https://arxiv.org/abs/2305.15798), [GitHub](https://github.com/Nota-NetsPresso/BK-SDM).
+
+
+## Examples with 🤗[Diffusers library](https://github.com/huggingface/diffusers).
+
+An inference code with the default PNDM scheduler and 50 denoising steps is as follows.
+
+```python
+import torch
+from diffusers import StableDiffusionPipeline
+
+pipe = StableDiffusionPipeline.from_pretrained("nota-ai/bk-sdm-v2-tiny", torch_dtype=torch.float16)
+pipe = pipe.to("cuda")
+
+prompt = "a black vase holding a bouquet of roses"
+image = pipe(prompt).images[0]  
+    
+image.save("example.png")
+```
+
+
+## Compression Method 
+
+Based on the [U-Net architecture](https://huggingface.co/nota-ai/bk-sdm-base#u-net-architecture) and [distillation retraining](https://huggingface.co/nota-ai/bk-sdm-base#distillation-pretraining) of BK-SDM, a reduced batch size (from 256 to 128) is used in BK-SDM-v2 for faster training speeds.
+
+- **Training Data**: 212,776 image-text pairs (i.e., 0.22M pairs) from [LAION-Aesthetics V2 6.5+](https://laion.ai/blog/laion-aesthetics/).
+- **Hardware:** A single NVIDIA A100 80GB GPU
+- **Gradient Accumulations**: 4
+- **Batch:** 128 (=4×32)
+- **Optimizer:** AdamW
+- **Learning Rate:** a constant learning rate of 5e-5 for 50K-iteration pretraining
+
+
+## Experimental Results 
+
+The following table shows the zero-shot results on 30K samples from the MS-COCO validation split. After generating 512×512 images with the PNDM scheduler and 25 denoising steps, we downsampled them to 256×256 for evaluating generation scores.
+
+- Our models were drawn at the 50K-th training iteration.

+
+#### Visual Analysis: Image Areas Affected By Each Word
+KD enables our models to mimic the SDM, yielding similar per-word attribution maps. The model without KD behaves differently, causing dissimilar maps and inaccurate generation (e.g., two sheep and unusual bird shapes).
