The field of software engineering is undergoing significant changes due to the rapid advances in large language models (LLMs). In just a few years, LLMs have gone from being advanced code autocomplete tools to AI agents that can design software, implement and correct modules, and help software engineers increase their productivity.
However, amidst the excitement surrounding AI-powered software engineering agents, it is important to separate the unsubstantiated hype from the true value that can be derived from these tools. Developers who learn to use the new generation of AI tools effectively will be able to achieve much more in less time.
There are three main ways in which LLMs are transforming the coding experience. The first is through the direct use of frontier models as coding assistants. Developers are leveraging chatbot interfaces like ChatGPT and Claude as coding assistants. These models are becoming increasingly proficient in generating code from text descriptions, improving existing code snippets, and assisting with debugging.
Recognizing the importance of software development as a use case, model providers are continuously enhancing the developer experience in chatbot interfaces. For example, Claude’s new Artifacts feature allows developers to view and run the code as they iterate over it with the model.
Another advanced application of AI coding assistants is the integration of LLMs into integrated development environments (IDEs) as plugins. These tools utilize project files and codebases as context to provide more accurate responses and accomplish more complex tasks.
Microsoft’s GitHub Copilot, launched a year before ChatGPT, was the first tool to enter this field. Initially, it was designed as a tool for writing code snippets within a code editor. However, it has since evolved into a full assistant that can help developers with various tasks in the development environment.
Amazon’s coding assistant Q offers similar features within the coding environment, including code autocomplete, design assistance, and code migration across different programming languages.
Several startups have also entered this space. Tabnine, for instance, claims to have millions of users and developers who use it to write 30% to 40% of their code. Other players include Replit, which offers a coding environment powered by its own LLM, and Codeium, an AI coding assistant that can integrate with multiple IDEs.
Apart from coding assistants, LLMs are also impacting software development through the concept of software engineering agents. These agents consist of multiple LLMs that are provided with different system prompts and are instructed to work together to complete a project.
For example, one agent can act as a designer, providing a high-level plan for completing a task, such as searching for resources, creating modules, and running them on a cloud platform. Another agent can offer a more detailed breakdown of each step, while a third agent can write code for a specific task. The code can then be reviewed by another agent for quality and sent back for corrections. Finally, another agent can bring all the pieces together, compile them, test them, and approve them for launch.
In theory, software engineering agents have the potential to receive a project description and complete it end-to-end. While AI startup Cognition’s AI software engineer, Devin, is still not open to the public, it has inspired other projects like OpenDevin, an open-source software engineering agent with similar capabilities. Other software development agents like GPT-engineer have also been showcasing impressive demos for several months.
However, amidst the buzz surrounding AI in software development, it is essential to acknowledge the limitations and realities. While AI assistants like GitHub Copilot have been shown to increase developers’ productivity and help them stay focused on their tasks, they are far from replacing mid-level or senior software engineers. Videos showcasing Devin’s capabilities have been criticized for being misleading, and it is clear that AI agents have their limitations.
Moreover, there are concerns about the safety of code generated by tools like Copilot. There is a risk that the models might generate insecure code due to the training data or the user’s code base. Tool providers are continuously working to add safeguards to prevent the generation of insecure code. Additionally, there is a risk of “automation blindness” where developers become too reliant on the AI-generated code without properly reviewing it. This can lead to unpredictable code that requires additional time for debugging.
While AI is not currently capable of replacing software developers entirely, it is evident that there is significant value in utilizing LLMs in software development. As AI continues to penetrate various domains, the demand for skilled software developers is also increasing. As the tools and models mature, we can expect even greater productivity gains in software engineering.
The upcoming VB Transform 2024 conference will delve deeper into these themes, featuring expert panels that discuss the cross-functional future of AI. It is an opportunity to explore the potential of AI in software development and learn from industry leaders.
