What is AI code generation?
AI code generation is a technology that is changing the way we approach programming. It involves the use of artificial intelligence (AI) to write or generate code. Modern code generation tools are based on large language models (LLMs) like GPT-4 or PaLM 2, trained on massive code datasets, which can understand nuanced instructions and generate human-like code in any programming language.
Code generation tools can write code much faster than a human programmer, and are more versatile because they can learn any technology or framework represented in their training dataset. They can carry out tasks like debugging, code optimization, coding of new functions or modules, and writing code documentation.
AI code generation is revolutionizing the way we code, and is already improving the productivity of millions of developers worldwide.
Applications of AI code generation
Here are some of the important applications of AI code generation:
- Automated code writing: AI code generation tools can significantly speed up the coding process, leaving programmers more time to focus on higher-level tasks. Automatic code writing is particularly useful for repetitive tasks or those where code needs to be adapted or repurposed.
- Bug detection and fixing: By analyzing the code, AI can identify potential errors and suggest fixes. This speeds up the debugging process and allows developers to cover more ground when testing their solutions.
- Code optimization: AI can analyze the code and suggest ways to make it more efficient. This could involve reducing the number of lines of code, improving the performance of the code, or even suggesting alternative approaches that could result in better results.
- Assisting in learning and understanding code: Modern coding assistants provide a chat interface that allows developers to “talk to their code.” Students, novice developers, or those learning new technologies can ask questions, and the AI coding assistant can provide examples and explanations.
- Generating code documentation: AI code generation tools can analyze existing code and generate comments or even detailed descriptions of how the code works. This can save time for developers, help expand the coverage of existing code documentation and update it more frequently.

Benefits of AI code generation
Increasing efficiency and productivity
By reducing the need for manual coding, and ensuring less time is spent on mundane, repetitive tasks, such as writing boilerplate code, AI code generation allows programmers to complete tasks faster and focus on more complex tasks. This can dramatically improve productivity and reduce time-to-market for software products.
Reducing errors
Human programmers, despite their best efforts, can make mistakes, which can lead to bugs and potential security vulnerabilities. AI code generation can help identify coding errors and dynamically suggest best practices, which can improve coding quality and also help upskill developers on issues like performance optimization and secure coding.

The future of AI for code is here
There are minor differences in features and capabilities between the AI code generation tools we reviewed, but in the end, all of them are able to generate human-like code and improve developer productivity. However, most of these tools were trained on a wide dataset of public code repositories, which include code that is not secure or uses non-permissive open source licenses. This means you must carefully review code generated by these tools for security and licensing issues.
In addition, tools offered as a cloud service raise important concerns about the privacy and confidentiality of your code. Leakage of your proprietary code is a possibility and you should carefully examine each provider’s security and compliance measures.
Luckily, there are AI code generation tools without any of these concerns. Tabnine stands out of the crowd with the highest standards of privacy and security. Unlike other AI coding tools, Tabnine places special emphasis on code privacy, intellectual property protection, and open-source compliance. With a dedicated mission to bring AI to every facet of software development, Tabnine ensures seamless integration while prioritizing the privacy and security of user code:
Code privacy
Tabnine’s AI models can be isolated, with no external connectivity and no data retention, ensuring that user code remains completely private and secure.
Intellectual property protection
Tabnine never stores user code and exclusively trains its generative AI on open-source code with permissive licenses, mitigating the risk of intellectual property litigation.
Open source compliance:
Tabnine ensures complete security by not training its AI models on code with non-permissive licenses, providing full transparency regarding the code used for training. In contrast, Copilot’s training on non-permissive open-source licenses, including GPL licenses with Copyleft clauses, could expose companies to legal risks. Although a filter is available to remove problematic code from suggestions, it may not always be foolproof, leaving the legal risk unresolved.
