Voyage AI

Use Voyage AI’s embeddings and reranking models through Portkey.

Quick Start

Get started with Voyage AI in under 2 minutes:

Python

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)

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

Add Provider in Model Catalog

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

1. Go to Model Catalog → Add Provider
2. Select Voyage AI
3. Enter your Voyage API key
4. Name your provider (e.g., voyage)

Voyage AI Capabilities

Embeddings

Generate high-quality embeddings:

Python

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)

Rerank

Portkey supports Voyage AI’s reranking models through a unified /v1/rerank endpoint.

curl https://api.portkey.ai/v1/rerank \
  -H "Content-Type: application/json" \
  -H "x-portkey-api-key: $PORTKEY_API_KEY" \
  -d '{
    "model": "@voyage-ai-prod/rerank-2",
    "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. Its capital is Saipan.",
      "Washington, D.C. (also known as simply Washington or D.C., and officially as the District of Columbia) is the capital of the United States. It is a federal district.",
      "Capital punishment (the death penalty) has existed in the United States since beforethe United States was a country. As of 2017, capital punishment is legal in 30 of the 50 states."
    ],
    "top_n": 3
  }'

Voyage-Specific Parameters

Parameter	Type	Description
truncation	boolean	Whether to truncate documents that exceed the model’s context length
=======

Reranking

Rerank documents for better search results:

Python

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)
