Show HN: Stateful AI agent on Cloudflare Workers free tier, with evals (github.com)

A developer has introduced a stateful AI agent that operates entirely on Cloudflare's free tier, leveraging innovative features such as Durable Objects for conversation management and R2 for long-term memory storage. Each conversation is managed by a dedicated Durable Object that retains state across sessions, utilizing markdown for memory storage, semantic recall through an embedding index, and a unique deep-research mode that explores various angles of inquiry through child Durable Objects. The agent measures its platform limits and provides detailed reports, ensuring a robust understanding of its operational boundaries. This project is significant for the AI/ML community as it highlights the potential to create sophisticated conversational agents without incurring direct costs, democratizing access to advanced AI tools. Key technical elements include compacting conversation history to optimize the use of context windows, scheduling tasks via Durable Object alarms, and maintaining a skill repository that the agent generates autonomously. The architecture is designed to ensure efficient resource management while allowing for seamless interactions, effectively demonstrating how modern cloud infrastructure can host an AI agent capable of handling complex tasks in real-time while remaining under resource constraints.
