Project Think: building the next generation of AI agents on Cloudflare

Project Think is Cloudflare's announcement of new primitives and an opinionated base class for the Agents SDK to build durable, sandboxed, long-running AI agents. It details features such as durable execution with fibers, sub-agents, persistent session storage, sandboxed Dynamic Workers, an execution ladder (workspace → worker → npm → browser → sandbox), and self-authored extensions, including code examples and integrations, aimed at making agent infrastructure serverless, durable, and secure by design.
