Cloudflare launches Project Think for AI agents

Cloudflare has introduced Project Think, an enhanced SDK for building sophisticated AI agents. This new framework offers primitives for durable execution, enabling agents to recover from crashes and maintain state across sessions. It also supports sub-agents for isolated tasks, sandboxed code execution for security, and persistent sessions for long-term memory. Project Think aims to address the scalability and cost challenges of current AI agents, which often run ephemerally on individual devices or expensive virtual machines. By leveraging Durable Objects, Cloudflare allows agents to be addressable entities that consume zero compute when idle, fundamentally changing the economics of deploying AI assistants at scale.
