Cloudflare highlights Flue agent framework

Flue shifts the focus of AI development from writing prompts to managing agent runtime and durability, underscoring that the hardest part of building production-grade agents is the infrastructure.

* Harness Architecture: Moves beyond simple chat wrappers by offering an application layer managing tools, filesystem access, and state persistence.

* Durable Workers Integration: Leveraging Cloudflare's Durable Objects makes Flue uniquely suited for stateful, long-lived, and durable agent execution.

* Lightweight Sandbox: The integration of a built-in virtual sandbox allows safe command and file operations without the overhead of heavy containers like Docker.
