1. Tutorial Introduction

DiffuCoder-7B-cpGRPO is a masked diffusion-based code generation model (dLLM) first proposed by the Apple team in a related paper on June 25, 2025. It has been trained with more than 20,000 carefully selected coding examples. The model aims to generate and edit code through iterative denoising, rather than the traditional left-to-right autoregressive generation. A notable feature of DiffuCoder-7B-cpGRPO is that it does not strictly rely on left-to-right generation to generate code, which makes it score 4.4% higher than other diffusion-based programming models in mainstream programming benchmarks. This non-sequential code generation capability enables it to show higher flexibility and efficiency in code editing and generation tasks. The relevant paper results are "DiffuCoder: Understanding and Improving Masked Diffusion Models for Code Generation".

This tutorial uses resources for a single RTX 4090 card.

1. After starting the container, click the API address to enter the Web interface

2. Usage steps

If "Bad Gateway" is displayed, it means the model is initializing. Since the model is large, please wait about 2-3 minutes and refresh the page.

Parameter Description

Advanced Settings:
- Temperature: controls the generation diversity, the higher the more random, the lower the more deterministic.
- Top-p: The cumulative threshold of probability sampling. The smaller the value, the more conservative the generation.
- Max-tokens: Limits the maximum length of a single generation of the model.
