Cloudflare Workers AI Lets Static Sites Run LLMs Free Without a Backend

Cloudflare Workers AI allows static websites to integrate large language models like Llama 3.3 70B without a backend server or exposed API keys. The service binds an AI model directly to a Cloudflare Worker via a two-line configuration, making the model accessible as a simple code variable. A developer added a product-requirement document generator to a static landing page in a single day using this approach. The free tier provides 10,000 neurons daily, translating to roughly 80 AI-generated responses per day at approximately 15 seconds each. The setup eliminates the need for a dedicated server, VM, or container, keeping the underlying site as plain static HTML.
