Workers AI is Cloudflare’s platform for running machine-learning models — language models, embeddings, image and speech models — on its own GPU network, called from inside a Worker. It lets you add inference to an application without managing GPUs or routing every request to a third-party model provider.
For many features Workers AI is the lowest-friction, lowest-cost way to add a model, because the inference runs on the same platform as the rest of the app and the data does not leave it. For others, a frontier model from Anthropic or OpenAI is the better fit; the engineering choice is about cost, quality, and where the data is allowed to go.
We measure that trade-off rather than guess it — see the cost-quality comparison below.
