Amazon Q Developer CLI now supports Anthropic’s Claude Sonnet 4 and allows developers to select specific Claude Sonnet models when performing tasks in the Q Developer CLI. With Claude Sonnet 4, you can optimize everyday development tasks through enhanced coding and reasoning capabilities, including performing complex actions, implementing bug fixes, running bash commands and developing new features with immediate feedback loops and more precise responses.
You can choose from premium models – Claude Sonnet 4, Claude 3.7 Sonnet, and Claude 3.5 Sonnet – using the “/model” command, launch a new chat with a specific model using the “q chat –model ” command, or configure default model settings using the “q settings chat.defaultModel ” command. This allows you to refine specific use cases such as long-running development tasks, while providing greater control over your development workflows and increased flexibility in model selection.
Anthropic’s Claude Sonnet 4 is available in the Q Developer CLI across all supported Amazon Q Developer regions at no additional cost. For more information, visit the Amazon Q Developer documentation.
