Cloudflare AI Gateway Review: Pricing & Comparison

Cloudflare AI Gateway: a free middle layer for AI requests

Cloudflare AI Gateway (developers.cloudflare.com/ai-gateway) is a proxy layer that sits between your AI application and the upstream LLM. Its core value proposition: nothing changes, you just gain monitoring, caching, rate limiting, and logging.

The most appealing part: it’s completely free. No markup, no monthly fee — all you need is a Cloudflare account.

What it can do

1. Request logging and monitoring

Every request that passes through Cloudflare AI Gateway gets logged: prompt content, response, latency, token consumption, estimated cost. This is the most basic LLMOps capability — without logs, you have no idea what your AI application is actually doing.

2. Caching

For identical requests, Cloudflare AI Gateway can return a cached result directly, without forwarding to the upstream API. For highly deterministic scenarios (FAQs, fixed-template generation), cache hit rates can reach 30-60%, directly saving that portion of your API bill.

3. Rate limiting

You can set request rate limits by API key, IP, or user ID, guarding against unexpected token blowouts (a crawler hitting your endpoint, a user polling maliciously).

4. Fallback routing (Beta)

Configure multiple upstreams (OpenAI as primary, Anthropic as backup) — when the primary goes down, it automatically switches to the backup, improving availability.

How to connect

Connecting to Cloudflare AI Gateway just requires swapping out the API’s base_url:

# Calling OpenAI directly, the original way
import openai
client = openai.OpenAI(api_key="sk-xxx")

# Switched to go through Cloudflare AI Gateway
client = openai.OpenAI(
    api_key="sk-xxx",
    base_url="https://gateway.ai.cloudflare.com/v1/{account_id}/{gateway_id}/openai"
)

# The calling convention is completely unchanged
response = client.chat.completions.create(
    model="gpt-5.5",
    messages=[{"role": "user", "content": "hello"}]
)

Similarly, for Anthropic just swap the base_url to Cloudflare’s gateway address — everything else stays the same.
