+
+# LangDB
+
+[LangDB](https://langdb.ai) is a high-performance enterprise AI gateway built in Rust, designed to govern, secure, and optimize AI traffic.
+
+LangDB provides OpenAI-compatible APIs, enabling developers to connect with multiple LLMs by changing just two lines of code. With LangDB, you can:
+
+- Provide access to all major LLMs
+- Enable plug-and-play functionality using any framework like Langchain, Vercel AI SDK, CrewAI, etc., for easy adoption.
+- Simplify implementation of tracing and cost optimization features, ensuring streamlined operations.
+- Dynamically route requests to the most suitable LLM based on predefined parameters.
+
+## Setup
+
+The LangDB provider is available via the `@langdb/vercel-provider` module. You can install it with:
+
+<Tabs items={['pnpm', 'npm', 'yarn']}>
+  <Tab>
+    <Snippet text="pnpm add @langdb/vercel-provider" dark />
+  </Tab>
+  <Tab>
+    <Snippet text="npm install @langdb/vercel-provider" dark />
+  </Tab>
+  <Tab>
+    <Snippet text="yarn add @langdb/vercel-provider" dark />
+  </Tab>
+</Tabs>
+
+## Provider Instance
+
+To create a LangDB provider instance, use the `createLangDB` function:
+
+```tsx
+import { createLangDB } from '@langdb/vercel-provider';
+
+const langdb = createLangDB({
+  apiKey: process.env.LANGDB_API_KEY, // Required
+  projectId: 'your-project-id', // Required
+  threadId: uuidv4(), // Optional
+  runId: uuidv4(), // Optional
+  label: 'code-agent', // Optional
+  headers: { 'Custom-Header': 'value' }, // Optional
+});
+```
+
+You can find your LangDB API key in the [LangDB dashboard](https://app.langdb.ai).
+
+## Examples
+
+You can use LangDB with the `generateText` or `streamText` function:
+
+### `generateText`
+
+```tsx
+import { createLangDB } from '@langdb/vercel-provider';
+import { generateText } from 'ai';
+
+const langdb = createLangDB({
+  apiKey: process.env.LANGDB_API_KEY,
+  projectId: 'your-project-id',
+});
+
+export async function generateTextExample() {
+  const { text } = await generateText({
+    model: langdb('openai/gpt-4o-mini'),
+    prompt: 'Write a Python function that sorts a list:',
+  });
+
+  console.log(text);
+}
+```
+
+### generateImage
+
+```tsx
+import { createLangDB } from '@langdb/vercel-provider';
+import { experimental_generateImage as generateImage } from 'ai';
+import fs from 'fs';
+import path from 'path';
+
+const langdb = createLangDB({
+  apiKey: process.env.LANGDB_API_KEY,
+  projectId: 'your-project-id',
+});
+
+export async function generateImageExample() {
+  const { images } = await generateImage({
+    model: langdb.image('openai/dall-e-3'),
+    prompt: 'A delighted resplendent quetzal mid-flight amidst raindrops',
+  });
+
+  const imagePath = path.join(__dirname, 'generated-image.png');
+  fs.writeFileSync(imagePath, images[0].uint8Array);
+  console.log(`Image saved to: ${imagePath}`);
+}
+```
+
+### embed
+
+```tsx
+import { createLangDB } from '@langdb/vercel-provider';
+import { embed } from 'ai';
+
+const langdb = createLangDB({
+  apiKey: process.env.LANGDB_API_KEY,
+  projectId: 'your-project-id',
+});
+
+export async function generateEmbeddings() {
+  const { embedding } = await embed({
+    model: langdb.textEmbeddingModel('text-embedding-3-small'),
+    value: 'sunny day at the beach',
+  });
+
+  console.log('Embedding:', embedding);
+}
+```
+
+
