Introduction

In the world of software engineering, code review is a crucial process for ensuring the quality, reliability, and maintainability of code. Over the years, code review has evolved from manual reviews by human developers to the use of tools and automated systems. In recent times, the emergence of large language models (LLMs) has introduced new possibilities for code review automation.

The Importance of Code Review

Code review plays a vital role in software development, serving as a cornerstone for defect identification, quality improvement, and knowledge sharing. It allows developers to catch errors, optimize code, and learn from each other's work. However, traditional code review processes can be time-consuming and resource-intensive, often leading to bottlenecks in the development pipeline.

The Role of Large Language Models in Code Review

Large language models, such as GPT-3 and GPT-4, have demonstrated remarkable capabilities in various natural language processing tasks. Leveraging their inherent understanding of programming languages, these models can be employed in code review automation. By training a specific reviewer model and applying low rank adaptation techniques, it becomes possible to Create an advanced code review system.

Introducing Plumber Reviewer: An Advanced Code Review Automation Tool

Plumber Reviewer is a cutting-edge code review automation tool built on the foundation of large language models. Utilizing parameter-efficient fine-tuning methods, Plumber Reviewer offers a comprehensive solution for code review processes. By incorporating review necessity prediction, review comment generation, and code refinement, it streamlines the code review workflow.

How Plumber Reviewer Works: Fine-Tuning and Low Rank Adaptation

Plumber Reviewer utilizes fine-tuning techniques to adapt a pre-trained LLM to the specific requirements of code review. By aligning the input representation with the pre-training format, the model can better leverage the capabilities of LLMs. Additionally, an initial stage of low rank adaptation helps improve task performance and enhances the model's ability to process natural language information.

Comparison with Existing Code Review Models

An extensive evaluation of Plumber Reviewer was conducted, comparing its performance against existing code review-focused models. Remarkably, even with a smaller model consisting of 6.7 billion parameters and limited tuning epochs, Plumber Reviewer achieved comparable performance. This highlights the potential of LLMs in code review automation, even with constrained resources.

Future Possibilities and Considerations

While Plumber Reviewer has shown promising results, it is essential to acknowledge the ever-evolving nature of large language models. As newer models, such as LLM2 and CodeLama, become available, it opens up possibilities for further exploration and improvement. Additionally, considerations of model size, Type, and methodologies need to be addressed to maximize the capabilities of LLMs in code review automation.

Conclusion

In conclusion, Plumber Reviewer represents a significant step forward in code review automation.
