Haley Berkoe sits down with Bradley Axen, who is leading many of Block's AI initiatives, including Buzz, a new open-source collaboration platform designed for humans and AI agents to work together. He also helped create goose, the open-source AI agent that was later donated to the Agentic AI Foundation under the Linux Foundation.
They discuss how Block is using AI internally with tools like Builder Bot to help engineers navigate massive codebases, automate incident response, and collaborate more effectively. Brad also shares his thoughts on where open-source AI is headed, why model flexibility matters, and how new open source AI contributors can get involved.
