Limitations of Using AI Coding Tools

While the rise of generative AI is transforming industries and unlocking opportunities, it also welcomes new challenges. While these tools cut down development costs, it also increases security, privacy, and copyright issues. Here are the top three limitations of using them:

Not Suitable for Complex Projects that Require Highly Customized Code 

Most of these tools generate code by analyzing existing code and patterns. This means it overcomes repetitive tasks, generates code faster, and provides optimized code. But when the project needs customized solutions, developers need new code development. Using an AI code generator on tasks that have never been done before with respect to their business niche can be challenging.

Lacks Readability 

Industries must partially rely on software development automation. However, reviewers and developers must verify if the code meets the expected results. As the code generated by these tools is based on natural language queries, the results may not be directly related to your particular use case. In such cases, it might get difficult for developers to understand the code. 

Results May be Inaccurate or Biased Due to Biased Training Data

Since AI generates code based on the datasets used for training, it could have potential bias. Most of the AI-powered tools are trained on GitHub repositories, which have over 250 repositories. These repositories are not monitored for the quality of code, or in most cases, the code might not be annotated in a way that is fit for training models. This could result in having code that might not be the best fit for your use case. 


AI-powered code solutions are a new approach that challenges the traditional coding process. It has changed how tasks are performed by developers. On the other hand, it has also simplified the software development life cycle. However, with software solutions all around the corner, it is essential to expedite the development and delivery of solutions to gain a competitive advantage.
