Project Think is Cloudflare's next-generation Agents SDK enabling scalable long-running AI agents through persistent infrastructure.
- •Durable execution with fibers enables crash recovery and checkpointing to survive platform interruptions.
- •Sub-agents delegate work to isolated child agents with separate SQLite storage and typed RPC.
- •Persistent sessions model conversations as tree-structured messages supporting forking and full-text search.
- •Sandboxed code execution replaces sequential tool calls with unified LLM-written programs, reducing tokens and latency.
- •Built on Durable Objects, agents consume zero compute while hibernated and activate on demand for efficient one-agent-per-task scaling.
