What is Cloudflare Workers AI?
Edge AI inference — 10,000 neurons/day, 50+ models.
Cloudflare Workers AI runs open-weight models directly on Cloudflare's global edge network. The free tier allocates 10,000 Neurons (compute units) per day, supporting 50+ models including Llama, Mistral, Gemma, DeepSeek, and Qwen. Unlike other providers, billing is based on Neurons rather than tokens, making it hard to predict exact request counts. Ideal for low-latency edge deployments.

Frequently Asked Questions
How many requests is 10,000 Neurons on Cloudflare Workers AI?
It depends on the model and prompt length. For Llama 3.2 3B with a 500-token prompt, ~10,000 Neurons ≈ 200-400 requests/day. Larger models consume more Neurons per request. Monitor your usage in the Cloudflare dashboard.
Do I need a Cloudflare Workers plan to use Workers AI?
No — the free Workers plan includes 10,000 Neurons/day for AI inference. You don't need to deploy any Workers code; just use the AI API endpoint directly.
Is Cloudflare Workers AI good for production?
The free tier is great for prototyping and low-volume apps. For production, the paid tier offers higher limits and SLAs. The edge network provides low global latency, which is a unique advantage.
