+Users can now use an [OpenAI Compatible endpoint](/ai-gateway/chat-completion/) 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.
+
+```js title="OpenAI SDK Example"
+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/chat/completions",
+});
+
+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](/ai-gateway/chat-completion/) can be combined with our [Universal Endpoint](/ai-gateway/universal/) 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](/ai-gateway/chat-completion/) documentation.
