Instructions to use d3LLM/d3LLM_Dream_Coder with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use d3LLM/d3LLM_Dream_Coder with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="d3LLM/d3LLM_Dream_Coder", trust_remote_code=True)
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoModel
model = AutoModel.from_pretrained("d3LLM/d3LLM_Dream_Coder", trust_remote_code=True, device_map="auto")

# d3LLM: Ultra-Fast Diffusion LLM using Pseudo-Trajectory Distillation 🚀

**d3LLM-Dream-Coder** is an ultra-fast diffusion language model introduced in the paper [d3LLM: Ultra-Fast Diffusion LLM using Pseudo-Trajectory Distillation](https://huggingface.co/papers/2601.07568). It is built on [Dream-org/Dream-Coder-v0-Instruct-7B](https://huggingface.co/Dream-org/Dream-Coder-v0-Instruct-7B).

## Model Description

d3LLM (pseuDo-Distilled Diffusion Large Language Model) is a framework designed to strike a balance between accuracy and parallelism in diffusion LLMs. It achieves up to 10× speedup over vanilla diffusion models like LLaDA/Dream and 5× speedup over autoregressive (AR) models. 

The model utilizes two primary innovations:
- **Pseudo-Trajectory Distillation**: A training method that teaches the model which tokens can be decoded confidently at early steps.
- **Entropy-Based Multi-Block Decoding**: An inference strategy using a KV-cache refresh mechanism to maintain accuracy while maximizing parallelism.

- **Demo**: [https://d3llm-team.github.io/](https://d3llm-team.github.io/)

## Usage

For detailed usage instructions, evaluation scripts, and training code, please refer to the official GitHub repository. Since the model uses a custom architecture, ensure you have `transformers==4.49.0` installed and use `trust_remote_code=True` when loading the model.
