+## Launches
+
+### Day 0: OpenAI JS SDK Integration
+
+```typescript /import { observeOpenAI } from "langfuse"/ /observeOpenAI/
+import OpenAI from "openai";
+import { observeOpenAI } from "langfuse";
+
+// wrap the OpenAI SDK
+const openai = observeOpenAI(new OpenAI());
+
+// use the OpenAI SDK as you normally would
+const res = await openai.chat.completions.create({
+  messages: [{ role: "system", content: "Tell me a story." }],
+});
+```
+
+We [launched](/changelog/2024-04-21-openai-integration-JS-SDK) a new wrapper for the OpenAI JS SDK. This integration, designed to enable easier monitoring of OpenAI API usage, features seamless observability with enhancements like automatic tracking of prompts, completions, and API errors, as well as insights into model usage and costs. After a soft launch that gathered user feedback for improvements, the integration is now fully available, complete with comprehensive [documentation](/docs/integrations/openai/js/get-started) and an [example notebook](/docs/integrations/openai/js/examples).
