Project Think
A stateful AI agent framework from Cloudflare that helps developers ship long-running, memory-enabled agent apps with subagents, code sandboxes, and persistent sessions on Cloudflare.
Tool overview
Based on the current evidence, Project Think is best understood as a developer-facing agent framework/SDK, not a consumer chatbot product and not a no-code automation tool. A more accurate analogy is an infrastructure/runtime layer for long-running agents on Cloudflare, with opinionated SDK primitives.
Its practical value is fairly consistent across the sources: persistent execution, continuous sessions, subagents, sandboxed code execution, and non-destructive compression plus retrieval over long histories. That suggests it is built to support agents that keep working across longer task chains and retain state over time, rather than just wrapping single-turn prompting. One Zhihu article also describes full history being kept in SQLite and searchable, which points to runtime and memory-layer design rather than just prompt orchestration.
On adoption cost and difficulty, the available sample mainly comes from official-intro reposts and Chinese explainers, so it supports a cautious judgment that this is developer-oriented and likely fits TypeScript/Cloudflare workflows. It does not support strong claims about production cost, API pricing, or operational overhead.
