Amazon Q Developer's functionality has expanded significantly since its initial launch as Amazon CodeWhisperer in 2022. The tool now offers:

1. Inline code suggestions based on comments and existing code
2. In-IDE chat for generating new code and explaining coding tasks
3. Integrated changes directly into the code editor
4. Dynamic selection of optimal AI models for each task through Amazon Bedrock integration 1

Practical Applications

The in-line chat feature demonstrates its utility through various practical applications:

1. Code refactoring: Developers can select multiple code methods, describe the desired refactoring, and the AI will consolidate them into a single function with optional parameters 1
