Project Think: building the next generation of AI agents on Cloudflare 2026-04-15 10 min read Today, we're introducing Project Think: the next generation of the Agents SDK . Project Think is a set of new primitives for building long-running agents (durable execution, sub-agents, sandboxed code execution, persistent sessions) and an opinionated base class that wires them all together. Use the primitives to build exactly what you need, or use the base class to get started fast. Something happened earlier this year that changed how we think about AI. Tools like Pi , OpenClaw , Claude Code , and Codex proved a simple but powerful idea: give an LLM the ability to read files, write code, execute it, and remember what it learned, and you get something that looks less like a developer tool and more like a general-purpose assistant. These coding agents aren't just writing code anymore. People are using them to manage calendars, analyze datasets, negotiate purchases, file taxes, and automate entire business workflows.…
