+## Usage as Universal Client
+
+You can use our OpenAI integration as a universal client to interact with other OpenAI-compatible APIs, such as [Perplexity.ai](https://docs.perplexity.ai/)
+
+```ts
+import { OpenAI } from "@trigger.dev/openai";
+
+const perplexity = new OpenAI({
+  id: "perplexity",
+  apiKey: process.env["PERPLEXITY_API_KEY"]!,
+  baseURL: "https://api.perplexity.ai",
+  icon: "brand-open-source",
+});
+```
+
+Since [Perplexity.ai](https://docs.perplexity.ai/) is compatible with OpenAI, you can use the same tasks as with OpenAI.
+
+```ts
+client.defineJob({
+  id: "perplexity-tasks",
+  name: "Perplexity Tasks",
+  version: "0.0.1",
+  trigger: eventTrigger({
+    name: "perplexity.tasks",
+  }),
+  integrations: {
+    perplexity,
+  },
+  run: async (payload, io, ctx) => {
+    await io.perplexity.chat.completions.create("chat-completion", {
+      model: "mistral-7b-instruct",
+      messages: [
+        {
+          role: "user",
+          content: "Create a good programming joke about background jobs",
+        },
+      ],
+    });
+
+    // Run this in the background
+    await io.perplexity.chat.completions.backgroundCreate("background-chat-completion", {
+      model: "mistral-7b-instruct",
+      messages: [
+        {
+          role: "user",
+          content: "If you were a programming language, what would you be and why?",
+        },
+      ],
+    });
+  },
+});
+```
+
+And you'll get the same experience in the Run Dashboard when viewing the logs:
