# Voyage AI

> Use Voyage AI's embeddings and reranking models through Portkey.

## Quick Start

Get started with Voyage AI in under 2 minutes:

<CodeGroup>
  ```python Python icon="python" theme={null}
  from portkey_ai import Portkey

  # 1. Install: pip install portkey-ai
  # 2. Add @voyage provider in model catalog
  # 3. Use it:

  portkey = Portkey(api_key="PORTKEY_API_KEY")

  embedding = portkey.embeddings.create(
      model="@voyage/voyage-3",
      input="Name the tallest buildings in Hawaii"
  )

  print(embedding.data[0].embedding)
  ```

  ```js Javascript icon="square-js" theme={null}
  import Portkey from 'portkey-ai'

  // 1. Install: npm install portkey-ai
  // 2. Add @voyage provider in model catalog
  // 3. Use it:

  const portkey = new Portkey({
      apiKey: "PORTKEY_API_KEY"
  })

  const embedding = await portkey.embeddings.create({
      model: "@voyage/voyage-3",
      input: "Name the tallest buildings in Hawaii"
  })

  console.log(embedding.data[0].embedding)
  ```

  ```python OpenAI Py icon="python" theme={null}
  from openai import OpenAI
  from portkey_ai import PORTKEY_GATEWAY_URL

  # 1. Install: pip install openai portkey-ai
  # 2. Add @voyage provider in model catalog
  # 3. Use it:

  client = OpenAI(
      api_key="PORTKEY_API_KEY",  # Portkey API key
      base_url=PORTKEY_GATEWAY_URL
  )

  embedding = client.embeddings.create(
      model="@voyage/voyage-3",
      input="Name the tallest buildings in Hawaii"
  )

  print(embedding.data[0].embedding)
  ```

  ```js OpenAI JS icon="square-js" theme={null}
  import OpenAI from "openai"
  import { PORTKEY_GATEWAY_URL } from "portkey-ai"

  // 1. Install: npm install openai portkey-ai
  // 2. Add @voyage provider in model catalog
  // 3. Use it:

  const client = new OpenAI({
      apiKey: "PORTKEY_API_KEY",  // Portkey API key
      baseURL: PORTKEY_GATEWAY_URL
  })

  const embedding = await client.embeddings.create({
      model: "@voyage/voyage-3",
      input: "Name the tallest buildings in Hawaii"
  })

  console.log(embedding.data[0].embedding)
  ```

  ```bash cURL icon="square-terminal" theme={null}
  # 1. Add @voyage provider in model catalog
  # 2. Use it:

  curl https://api.portkey.ai/v1/embeddings \
    -H "Content-Type: application/json" \
    -H "x-portkey-api-key: $PORTKEY_API_KEY" \
    -d '{
      "model": "@voyage/voyage-3",
      "input": "Name the tallest buildings in Hawaii"
    }'
  ```
</CodeGroup>

<Note>
  **Tip:** You can also set `provider="@voyage"` in `Portkey()` and use just `model="voyage-3"` in the request.
</Note>

## Add Provider in Model Catalog

Before making requests, add Voyage AI to your Model Catalog:

1. Go to [**Model Catalog → Add Provider**](https://app.portkey.ai/model-catalog/providers)
2. Select **Voyage AI**
3. Enter your [Voyage API key](https://dash.voyageai.com/)
4. Name your provider (e.g., `voyage`)

## Voyage AI Capabilities

### Embeddings

Generate high-quality embeddings:

<CodeGroup>
  ```python Python theme={null}
  from portkey_ai import Portkey

  portkey = Portkey(api_key="PORTKEY_API_KEY", provider="@voyage")

  embedding = portkey.embeddings.create(
      model="voyage-3",
      input="Name the tallest buildings in Hawaii"
  )

  print(embedding.data[0].embedding)
  ```

  ```javascript Node.js theme={null}
  import Portkey from 'portkey-ai';

  const portkey = new Portkey({
      apiKey: 'PORTKEY_API_KEY',
      provider: '@voyage'
  });

      const embedding = await portkey.embeddings.create({
      model: "voyage-3",
      input: "Name the tallest buildings in Hawaii"
      });

  console.log(embedding.data[0].embedding);
  ```
</CodeGroup>

### Reranking

Rerank documents for better search results:

<CodeGroup>
  ```python Python theme={null}
  from portkey_ai import Portkey

  portkey = Portkey(api_key="PORTKEY_API_KEY", provider="@voyage")

      response = portkey.post(
              "/rerank",
              model="rerank-2-lite",
              query="What is the capital of the United States?",
              documents=[
                  "Carson City is the capital city of the American state of Nevada.",
          "The Commonwealth of the Northern Mariana Islands is a group of islands in the Pacific Ocean.",
          "Washington, D.C. is the capital of the United States.",
          "Capital punishment has existed in the United States since before it was a country."
              ]
          )

      print(response)
  ```

  ```javascript Node.js theme={null}
  import Portkey from 'portkey-ai';

  const portkey = new Portkey({
      apiKey: 'PORTKEY_API_KEY',
      provider: '@voyage'
  });

  const response = await portkey.post(
      "/rerank",
      {
          model: "rerank-2-lite",
          query: "What is the capital of the United States?",
          documents: [
              "Carson City is the capital city of the American state of Nevada.",
              "The Commonwealth of the Northern Mariana Islands is a group of islands in the Pacific Ocean.",
              "Washington, D.C. is the capital of the United States.",
              "Capital punishment has existed in the United States since before it was a country."
          ]
      }
  );

  console.log(response);
  ```
</CodeGroup>
