Milvus

Milvus is an open-source vector database built for GenAI applications. It is built to be performant and scale to tens of billions of vectors with minimal performance loss. Portkey provides a proxy to Milvus - you can log your Milvus requests and manage auth for Qdrant clusters on Portkey.

Portkey SDK Integration with Milvus

Portkey provides a consistent API to interact with models from various providers. To integrate Milvus with Portkey:

1. Install the Portkey SDK

Add the Portkey SDK to your application to interact with Milvus through Portkey’s gateway.

NodeJS
Python

npm install --save portkey-ai

pip install portkey-ai

2. Create a New Integration

To use Milvus with Portkey, get your Milvus API key and create a new Milvus integration on Portkey.

NodeJS SDK
Python SDK
OpenAI Python SDK
OpenAI Node SDK

import Portkey from 'portkey-ai'

const portkey = new Portkey({
    apiKey: "PORTKEY_API_KEY", // defaults to process.env["PORTKEY_API_KEY"]
    provider:"@PROVIDER" // Your Milvus provider slug
})

from portkey_ai import Portkey

portkey = Portkey(
    api_key="PORTKEY_API_KEY",  # Replace with your Portkey API key
    provider="@PROVIDER"   # Replace with your Milvus provider slug
)

from openai import OpenAI

from portkey_ai import PORTKEY_GATEWAY_URL, createHeaders

client = OpenAI(
    api_key="MILVUS_API_KEY",
    base_url=PORTKEY_GATEWAY_URL,
    default_headers=createHeaders(
        api_key="PORTKEY_API_KEY",
        provider="milvus",
        custom_host="MILVUS_HOST" # Replace with your Milvus host example: https://in03-34d7b37f7ee12c7.serverless.gcp-us-west1.cloud.zilliz.com
    )
)

import OpenAI from "openai";

import { PORTKEY_GATEWAY_URL, createHeaders } from "portkey-ai";

const client = new OpenAI({
  apiKey: "MILVUS_API_KEY",
  baseURL: PORTKEY_GATEWAY_URL,
  defaultHeaders: createHeaders({
    provider: "milvus",
    apiKey: "PORTKEY_API_KEY",
    customHost: "MILVUS_HOST" // Replace with your Milvus host example: https://in03-34d7b37f7ee12c7.serverless.gcp-us-west1.cloud.zilliz.com
  }),
});

print(response)
