# DFloat11 Compressed Model: `ByteDance-Seed/BAGEL-7B-MoT`
This model uses **DFloat11** lossless compression. It's 32% smaller than the original BFloat16 model, yet produces bit-identical outputs and runs efficiently on GPUs.
### 📊 Performance Comparison
| Metric | BAGEL-7B-MoT (BFloat16) | BAGEL-7B-MoT (DFloat11) |
| ---------------------------------- | ------------------------- | ------------------------- |
| Model Size | 29.21 GB | 19.89 GB |
| Peak GPU Memory<br>(1024x1024 image generation) | 30.07 GB | 21.76 GB |
| Generation Time<br>(on an A100 GPU) | 54 seconds | 58 seconds |
### 🔍 How It Works
We apply Huffman coding to the exponent bits of BFloat16 model weights, which are highly compressible. We leverage hardware-aware algorithmic designs to enable highly efficient, on-the-fly weight decompression directly on the GPU.
