Portkey SDK Integration with Nebius AI Models

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

1. Install the Portkey SDK

Add the Portkey SDK to your application to interact with Nebius AI’s API through Portkey’s gateway.

NodeJS

npm install --save portkey-ai

2. Initialize Portkey with the Virtual Key

To use Nebius AI with Portkey, get your API key from here, then add it to Portkey to create the virtual key.

NodeJS SDK

import Portkey from 'portkey-ai'

const portkey = new Portkey({
    apiKey: "PORTKEY_API_KEY", // defaults to process.env["PORTKEY_API_KEY"]
    virtualKey: "VIRTUAL_KEY" // Your Nebius Virtual Key
})

3. Invoke Chat Completions with Nebius AI

Use the Portkey instance to send requests to Nebius AI. You can also override the virtual key directly in the API call if needed.

NodeJS SDK

const chatCompletion = await portkey.chat.completions.create({
    messages: [{ role: 'user', content: 'Say this is a test' }],
    model: 'deepseek-ai/DeepSeek-V3',
});

console.log(chatCompletion.choices);d

Managing Nebius AI Prompts

You can manage all prompts to Nebius AI in the Prompt Studio. All the current models of Nebius AI are supported and you can easily start testing different prompts.

Once you’re ready with your prompt, you can use the portkey.prompts.completions.create interface to use the prompt in your application.
