## Model Description

**d3LLM-LLaDA** is an ultra-fast diffusion language model that strikes a balance between accuracy and parallelism. It uses pseudo-trajectory distillation to teach the model which tokens can be decoded confidently at early steps, and employs an entropy-based multi-block decoding mechanism with KV-cache refresh during inference.

## Key Features

- 🚀 **High throughput:** 5.0× faster than autoregressive models (Qwen-2.5-7B-it) on H100 GPU and 3.5× faster on A100 GPU.
- 📊 **High AUP:** Achieves high Accuracy Under Parallelism scores across benchmarks.
- 🔧 **Task Optimization:** Specifically optimized for coding and math reasoning tasks.

## Installation
