PRODUCT OVERVIEW
What is Cloudflare Workers AI?
Cloudflare Workers AI is a serverless inference platform that lets developers run machine learning models on GPUs across Cloudflare's global network without managing or scaling infrastructure. It offers a curated catalog of 50+ open-source models for tasks such as text generation, image classification, and object detection, invokable from Workers, Pages, or anywhere via the Cloudflare REST API. A pay-for-what-you-use pricing model means you only pay for consumed resources, and the service is available on Free and Paid plans. It integrates with the broader developer platform, including AI Gateway for caching and rate limiting, Vectorize for vector search, and storage products like R2, D1, and KV. Developers can also use OpenAI-compatible endpoints, function calling, JSON mode, fine-tuning with LoRA adapters, and batch APIs to build AI applications.
