A major objective in the study of Artificial Intelligence is the development of AI systems that can provide useful computer programs to address challenging issues. Much progress has been made in this direction in recent years, especially with the remarkable successes of massive pretrained Large Language Models (LLMs). These models were first created for natural language comprehension, but they have now expanded to include the ability to generate and comprehend code and text. Notable progress has been made in producing code from descriptions of natural language problems as a result of this development.

LLMs have already proven themselves capable of handling straightforward programming tasks, as seen by their achievements in benchmarks such as MBPP and HumanEval. However, these models encounter significant difficulties when trying to solve more difficult and competitive programming tasks. Their propensity to provide code solutions as monolithic blocks rather than decomposing them into logical subtasks and reusable sub-modules is one of the primary causes of their difficulties. On the other hand, when faced with complex problems, skilled human programmers instinctively write modular and abstract code. By reusing previously created modules, they effectively expand upon their current expertise.

In a recent research, a team of researchers from Salesforce Research has introduced CodeChain, an innovative framework for bridging the gap between LLMs and human developers. With a sequence of self-revisions driven by representative sub-modules developed in earlier iterations, this framework aims to improve the process of developing modularized code. CodeChain tells the LLM to write modularized code using a chain-of-thought approach. The intention is to motivate the model to approach problem-solving in terms of logical subtasks and submodules.

A sequence of self-revisions forms the basis of CodeChain. There are two iterative phases in it, which are as follows.

Sub-Module Extraction and Clustering: In this stage, sub-modules are found by analyzing the code that the LLM produced. After that, these sub-modules are arranged into clusters. Representative sub-modules are chosen from each cluster. These representations are thought to be more widely applicable and reusable.

Prompt Augmentation and Re-Generation: The initial chain-of-thought prompt is enhanced and regenerated by integrating the chosen module implementations from the preceding stage. After that, the LLM is told to produce fresh modularized solutions once more. As a result, the model can effectively expand upon the information and understanding that it has obtained from earlier iterations.

CodeChain has a great impact on code generation. The team has shared that the modularity and accuracy of generated solutions are greatly improved by pushing the LLM to build upon and reuse pre-existing, verified sub-modules. Relative pass@1 improvements have been achieved by the framework on APPS of 35% and on CodeContests of an astounding 76%. These gains are shown in a variety of LLMs, including open-source LLMs like WizardCoder and models from OpenAI. Comprehensive ablation studies have been carried out to gain a deeper understanding of the elements that have contributed to CodeChain’s success. Aspects such as prompting techniques, the number of clusters employed, the sizes of the LLM models, and the caliber of the programs produced are all examined in these studies. The understanding obtained from these investigations clarifies why CodeChain is so successful in raising the caliber and modularity of code produced by LLMs.

To sum up, CodeChain is a revolutionary development in the field of large language model code generation. It achieves this by promoting modularity and facilitating self-revisions by reusing previously created sub-modules, hence bridging the gap between LLMs and seasoned human programmers.
