What is CodeFuse?

CodeFuse is an AI coding assistant from Ant Group for developers who want support with day-to-day software development work. It is described as a code-focused model fine-tuned from Ant Group’s internally developed foundation model, with its capabilities centered on understanding and generating programming code.

Developers can use CodeFuse through IDE plugins while writing code or selecting existing code for assistance. Its workflow covers completion, comments, explanations, unit-test generation, and code improvement, making it suitable for implementation tasks as well as reading, testing, and refining code across a broad range of programming languages.

Key features of CodeFuse

  • Code completion

    While code is being written, CodeFuse provides inline completion for a single line and snippet completion for multiple lines, helping developers continue an implementation in context.

  • Comments and explanations

    For selected code, CodeFuse can generate comments and explain the apparent intent of the implementation, helping developers read existing code and understand what a function or code section is doing.

  • Unit-test generation

    After business logic has been written, developers can select code and generate unit tests with business-oriented meaning, providing additional test cases and supporting the discovery of potential issues.

  • Code optimization

    CodeFuse analyzes a selected code fragment through code understanding and static source analysis, then proposes improvement ideas and can generate a code patch based on those suggestions.
