Anthropic’s Claude Sonnet 4.5 Enhances Developer Productivity with Amazon Q CLI and Kiro Integration
In a significant advancement for developers, Anthropic’s Claude Sonnet 4.5, acclaimed as the top coding model by SWE-Bench, has been integrated into the Amazon Q command line interface (CLI) and the Kiro platform. This development promises to revolutionize how developers approach coding and enhance their productivity significantly.
A Leap in Developer Productivity
Recently, I had the opportunity to conduct an AI-assisted development workshop with a global client. During this intense four-day session, the potential of Amazon Q CLI was evident as it drastically reduced development time. A feature that would typically take weeks to implement was completed in just a day. The integration of Anthropic’s Claude Sonnet 4.5 into Amazon Q CLI is expected to further boost this productivity, offering developers a more efficient way to tackle complex coding tasks.
The implications of this development are immense. Developers can now leverage the capabilities of Claude Sonnet 4.5 to streamline their coding processes, allowing for more time to focus on innovation and problem-solving. This advancement is particularly beneficial for companies looking to stay ahead in the competitive tech landscape by rapidly developing and deploying new features.
Preparing for AWS re:Invent 2025
In preparation for the upcoming AWS re:Invent 2025, my co-speaker and I are excited to showcase a live coding demonstration using Kiro. This demonstration will highlight the integration of Claude Sonnet 4.5 in Kiro, illustrating how it can be used to modernize legacy codebases effectively. Attendees of AWS re:Invent 2025 in Las Vegas from December 1–5 will have the opportunity to witness this live demo, along with over a thousand other sessions focused on cloud and AI technologies.
Recent Launches That Caught Attention
Several other noteworthy launches have taken place recently, capturing the interest of developers and tech enthusiasts alike:
