Cloudflare Workers AI free tier

What you get

Serverless model inference on Cloudflare, with an OpenAI-compatible API and a daily free allowance

Free models

The free offer is a budget for model usage across the catalog. See Limits for its conditions and Connect for API details, where available.

Limits, in the vendor’s words

10,000 neurons/day per account. All limits reset daily at 00:00 UTC.

Free text generation: 300 requests/minute per account

Past the free allowance “further operations will fail with an error”. Some models require a paid billing method through the Workers Paid plan or prepaid AI Gateway credits even if neurons remain; the pricing page identifies them. The free text-generation rate does not apply to models requiring paid access.

Where it is offered

The vendor names no country it keeps the offer from (source, read 2026-09-26).

What happens to what you send

What you send is not used to train models. In the vendor’s words: “Cloudflare does not use Customer Content processed by Workers AI to train AI models.” (source).
