View on XCloudflare Launches Project Think to Build Durable Serverless AI Agents
Cloudflare· Updated
Cloudflare introduced Project Think, a preview of its next-generation Agents SDK that provides primitives for long-running, stateful AI agents. The platform enables agents to survive crashes, delegate tasks to sub-agents, and execute code in sandboxed environments while costing nothing when idle.
Cloudflare, a network and security company offering edge computing services, launched Project Think, a suite of primitives for the Agents SDK designed to build persistent AI agents. Key additions include fibers for durable execution, sub-agents for task delegation, and a tiered execution ladder.
Current coding agents often run locally or on expensive virtual machines, which limits scaling. By leveraging Durable Objects (stateful storage and compute at the network edge) and Dynamic Workers, this update shifts agents to a serverless model where each task gets a unique instance that hibernates when inactive, reducing idle costs to zero.
You can now use the Think base class to handle chat lifecycles or integrate primitives like runFiber() into existing agents. The preview is available via the @cloudflare/think package on npm, providing access to the execution ladder including Dynamic Workers and Sandboxes.
