What is code generation?

Definition

AI code generation translates natural-language requests and project context into source files, functions, tests, configuration, or other software artifacts. Systems can generate a first draft, complete a local section, or participate in an iterative build-and-test loop.

Generated code can accelerate exploration, but plausible output is not proof of correctness. Developers still need to verify requirements, dependencies, behavior, security, performance, maintainability, licensing, and failure handling.

ELI5

AI code generation creates source code from instructions, examples, existing project files, or visual references. It can produce anything from one suggested line to tests, interface components, and a larger feature when enough useful context is available.

For example, a developer might describe a search form and receive the component, server request, and tests. The output is still a proposed implementation, so it must be run and reviewed for incorrect assumptions, security problems, accessibility, and fragile behavior.

What can AI code generation produce?

It can produce functions, components, applications, tests, scripts, queries, configuration, documentation examples, migrations, and edits to existing code.

Why must generated code be reviewed?

It can contain incorrect assumptions, security flaws, missing requirements, weak error handling, unsuitable dependencies, regressions, or code that works only in the demonstration case.

Code generation uses AI or another automated system to create source code from instructions, examples, schemas, or higher-level specifications.
