AI models and chat Added on October 31st, 2026 Checked and working on October 31st, 2026

What it does

Workers AI runs open AI models on Cloudflare's global network: text generation and chat, text embeddings, image generation, image classification, speech recognition, translation and summarisation. Call the models from a Cloudflare Worker or over the REST API with an API token. Responses are JSON. The Workers Free plan includes 10,000 'neurons' (Cloudflare's unit of AI compute) per day; requests above that fail until the daily reset, unless you move to the paid plan. Cloudflare's official MCP server at https://mcp.cloudflare.com/mcp lets AI agents use the Cloudflare API, Workers AI included.
