AI Gateway - Automatically retry on upstream provider failures on AI Gateway

Thu, 02 Apr 2026 00:00:00 GMT

AI Gateway now supports automatic retries at the gateway level. When an upstream provider returns an error, your gateway retries the request based on the retry policy you configure, without requiring any client-side changes.

You can configure the retry count (up to 5 attempts), the delay between retries (from 100ms to 5 seconds), and the backoff strategy (Constant, Linear, or Exponential). These defaults apply to all requests through the gateway, and per-request headers can override them.

This is particularly useful when you do not control the client making the request and cannot implement retry logic on the caller side. For more complex failover scenarios — such as failing across different providers — use Dynamic Routing.

For more information, refer to Manage gateways.

AI Gateway - Log AI Gateway request metadata without storing payloads

Tue, 17 Mar 2026 00:00:00 GMT

AI Gateway now supports the cf-aig-collect-log-payload header, which controls whether request and response bodies are stored in logs. By default, this header is set to true and payloads are stored alongside metadata. Set this header to false to skip payload storage while still logging metadata such as token counts, model, provider, status code, cost, and duration.

This is useful when you need usage metrics but do not want to persist sensitive prompt or response data.

curl https://gateway.ai.cloudflare.com/v1/$ACCOUNT_ID/$GATEWAY_ID/openai/chat/completions \
  --header "Authorization: Bearer $TOKEN" \
  --header 'Content-Type: application/json' \
  --header 'cf-aig-collect-log-payload: false' \
  --data '{
    "model": "gpt-4o-mini",
    "messages": [
      {
        "role": "user",
        "content": "What is the email address and phone number of user123?"
      }
    ]
  }'

For more information, refer to Logging.

AI Gateway - Get started with AI Gateway automatically

Mon, 02 Mar 2026 00:00:00 GMT

You can now start using AI Gateway with a single API call — no setup required. Use default as your gateway ID, and AI Gateway creates one for you automatically on the first request.

To try it out, create an API token with AI Gateway - Read, AI Gateway - Edit, and Workers AI - Read permissions, then run:

curl -X POST https://gateway.ai.cloudflare.com/v1/$CLOUDFLARE_ACCOUNT_ID/default/compat/chat/completions \
  --header "cf-aig-authorization: Bearer $CLOUDFLARE_API_TOKEN" \
  --header 'Content-Type: application/json' \
  --data '{
    "model": "workers-ai/@cf/meta/llama-3.3-70b-instruct-fp8-fast",
    "messages": [
      {
        "role": "user",
        "content": "What is Cloudflare?"
      }
    ]
  }'

AI Gateway gives you logging, caching, rate limiting, and access to multiple AI providers through a single endpoint. For more information, refer to Get started.

AI Gateway, Workers AI - AI dashboard experience improvements

Thu, 19 Feb 2026 00:00:00 GMT

Workers AI and AI Gateway have received a series of dashboard improvements to help you get started faster and manage your AI workloads more easily.

Navigation and discoverability

AI now has its own top-level section in the Cloudflare dashboard sidebar, so you can find AI features without digging through menus.

Onboarding and getting started

Getting started with AI Gateway is now simpler. When you create your first gateway, we now show your gateway's OpenAI-compatible endpoint and step-by-step guidance to help you configure it. The Playground also includes helpful prompts, and usage pages have clear next steps if you have not made any requests yet.

We've also combined the previously separate code example sections into one view with dropdown selectors for API type, provider, SDK, and authentication method so you can now customize the exact code snippet you need from one place.

Dynamic Routing

The route builder is now more performant and responsive.
You can now copy route names to your clipboard with a single click.
Code examples use the Universal Endpoint format, making it easier to integrate routes into your application.

Observability and analytics

Small monetary values now display correctly in cost analytics charts, so you can accurately track spending at any scale.

Accessibility

Improvements to keyboard navigation within the AI Gateway, specifically when exploring usage by provider.
Improvements to sorting and filtering components on the Workers AI models page.

For more information, refer to the AI Gateway documentation.

Secrets Store, AI Gateway, SSL/TLS - Manage and deploy your AI provider keys through Bring Your Own Key (BYOK) with AI Gateway, now powered by Cloudflare Secrets Store

Mon, 25 Aug 2025 11:00:00 GMT

Cloudflare Secrets Store is now integrated with AI Gateway, allowing you to store, manage, and deploy your AI provider keys in a secure and seamless configuration through Bring Your Own Key. Instead of passing your AI provider keys directly in every request header, you can centrally manage each key with Secrets Store and deploy in your gateway configuration using only a reference, rather than passing the value in plain text.

You can now create a secret directly from your AI Gateway in the dashboard by navigating into your gateway -> Provider Keys -> Add.

You can also create your secret with the newly available ai_gateway scope via wrangler, the Secrets Store dashboard, or the API.

Then, pass the key in the request header using its Secrets Store reference:

curl -X POST https://gateway.ai.cloudflare.com/v1/<ACCOUNT_ID>/my-gateway/anthropic/v1/messages \
 --header 'cf-aig-authorization: ANTHROPIC_KEY_1 \
 --header 'anthropic-version: 2023-06-01' \
 --header 'Content-Type: application/json' \
 --data  '{"model": "claude-3-opus-20240229", "messages": [{"role": "user", "content": "What is Cloudflare?"}]}'

Or, using Javascript:

import Anthropic from '@anthropic-ai/sdk';


const anthropic = new Anthropic({
 apiKey: "ANTHROPIC_KEY_1",
 baseURL: "https://gateway.ai.cloudflare.com/v1/<ACCOUNT_ID>/my-gateway/anthropic",
});


const message = await anthropic.messages.create({
 model: 'claude-3-opus-20240229',
 messages: [{role: "user", content: "What is Cloudflare?"}],
 max_tokens: 1024
});

AI Gateway - AI Gateway adds OpenAI compatible endpoint

Tue, 03 Jun 2025 00:00:00 GMT

Users can now use an OpenAI Compatible endpoint in AI Gateway to easily switch between providers, while keeping the exact same request and response formats. We're launching now with the chat completions endpoint, with the embeddings endpoint coming up next.

To get started, use the OpenAI compatible chat completions endpoint URL with your own account id and gateway id and switch between providers by changing the model and apiKey parameters.

import OpenAI from "openai";
const client = new OpenAI({
  apiKey: "YOUR_PROVIDER_API_KEY", // Provider API key
  baseURL:
    "https://gateway.ai.cloudflare.com/v1/{account_id}/{gateway_id}/compat",
});

const response = await client.chat.completions.create({
  model: "google-ai-studio/gemini-2.0-flash",
  messages: [{ role: "user", content: "What is Cloudflare?" }],
});

console.log(response.choices[0].message.content);

Additionally, the OpenAI Compatible endpoint can be combined with our Universal Endpoint to add fallbacks across multiple providers. That means AI Gateway will return every response in the same standardized format, no extra parsing logic required!

Learn more in the OpenAI Compatibility documentation.

AI Gateway - AI Gateway launches Realtime WebSockets API

Fri, 21 Mar 2025 00:00:00 GMT

The Realtime WebSockets API works with the OpenAI Realtime API, Google Gemini Live API, and supports real-time text and speech interactions with models from Cartesia, and ElevenLabs.

Here's how you can connect AI Gateway to OpenAI's Realtime API using WebSockets:

import WebSocket from "ws";

const url =
  "wss://gateway.ai.cloudflare.com/v1/<account_id>/<gateway>/openai?model=gpt-4o-realtime-preview-2024-12-17";
const ws = new WebSocket(url, {
  headers: {
    "cf-aig-authorization": process.env.CLOUDFLARE_API_KEY,
    Authorization: "Bearer " + process.env.OPENAI_API_KEY,
    "OpenAI-Beta": "realtime=v1",
  },
});

ws.on("open", () => console.log("Connected to server."));
ws.on("message", (message) => console.log(JSON.parse(message.toString())));

ws.send(
  JSON.stringify({
    type: "response.create",
    response: { modalities: ["text"], instructions: "Tell me a joke" },
  }),
);

AI Gateway - Request timeouts and retries with AI Gateway

Thu, 06 Feb 2025 00:00:00 GMT

AI Gateway adds additional ways to handle requests - Request Timeouts and Request Retries, making it easier to keep your applications responsive and reliable.

Timeouts and retries can be used on both the Universal Endpoint or directly to a supported provider.

Request timeouts A request timeout allows you to trigger fallbacks or a retry if a provider takes too long to respond.

To set a request timeout directly to a provider, add a cf-aig-request-timeout header.

curl https://gateway.ai.cloudflare.com/v1/{account_id}/{gateway_id}/workers-ai/@cf/meta/llama-3.1-8b-instruct \
 --header 'Authorization: Bearer {cf_api_token}' \
 --header 'Content-Type: application/json' \
 --header 'cf-aig-request-timeout: 5000'
 --data '{"prompt": "What is Cloudflare?"}'

Request retries A request retry automatically retries failed requests, so you can recover from temporary issues without intervening.

To set up request retries directly to a provider, add the following headers:

cf-aig-max-attempts (number)
cf-aig-retry-delay (number)
cf-aig-backoff ("constant" | "linear" | "exponential)

AI Gateway - AI Gateway adds Cerebras, ElevenLabs, and Cartesia as new providers

 --header 'content-type: application/json' \
 --header 'Authorization: Bearer CEREBRAS_TOKEN' \
 --data '{
    "model": "llama-3.3-70b",
    "messages": [
        {
            "role": "user",
            "content": "What is Cloudflare?"
        }
    ]
}'
