Cloudflare Workers AI lets developers run open-source AI models on GPUs in Cloudflare's network, paying only for what they use.
In plain words
It is serverless: you do not rent or manage a GPU. Your code, such as a Cloudflare Worker or any app using the REST API, calls a model from Cloudflare's catalogue and gets the result back. The catalogue covers tasks like text generation, image classification and object detection, and it sits alongside other Cloudflare tools such as a vector database and an AI gateway.
A quick example
Imagine a small website that wants to tag uploaded photos. A Worker receives each upload, sends the image to an image-classification model on Workers AI, and saves the returned labels, with no server of its own.
Where you'll meet it
- Adding AI features to apps already built on Cloudflare.
- Running open models without managing GPUs.
