Cloudflare Workers AI

About

Cloudflare Workers AI is a serverless AI inference platform that runs on Cloudflare's global GPU network — over 300 locations worldwide — enabling AI model inference at the edge with minimal latency. Unlike traditional AI platforms that route requests to central data centers, Workers AI runs models close to your users, making it ideal for latency-sensitive applications like real-time chatbots, content moderation, translation, and image analysis where response time matters. Workers AI provides access to popular open-source models including Llama 3, Mistral, Phi-4, Gemma, Whisper (speech-to-text), Stable Diffusion, and many more, all available through a simple API integrated with Cloudflare's ecosystem. The platform charges only for compute time used (not per-token), making costs predictable and often lower than dedicated AI API providers for moderate workloads. For developers already using Cloudflare Workers for serverless functions, Workers AI integrates seamlessly — you can build an entire AI application using Workers for logic, KV/R2 for storage, and Workers AI for inference, all within Cloudflare's free tier (limited daily requests). Workers AI also supports fine-tuned models via custom inference, letting you deploy your own trained models on Cloudflare's global network. The key advantage is data locality and compliance: inference runs on Cloudflare's global edge network, so data doesn't leave the region you specify. For developers building AI features who want global low-latency, predictable pricing, and seamless integration with their existing Cloudflare infrastructure, Workers AI provides the most geographically distributed inference platform available.
