AI-Generated Code refers to code automatically created using artificial intelligence (AI) technology, designed to follow programming logic and syntax conventions. These tools assist with a wide range of development tasks, including requirement analysis, code writing, optimization, and debugging. They are typically trained on large-scale code datasets and can understand user inputs in natural language or partial code, generating programs that are logically sound and well-structured. Common AI code generation technologies are based on natural language processing (NLP) and deep learning, with models such as GitHub Copilot, CodeGeeX, ChatGPT (GPT-4), and AlphaCode leading the field.
