Hugging Face

Portkey provides a robust and secure gateway to facilitate the integration of various Large Language Models (LLMs) into your applications, including all the text generation models supported by Huggingface’s Inference endpoints.

With Portkey, you can take advantage of features like fast AI gateway access, observability, prompt management, and more, all while ensuring the secure management of your LLM API keys through a virtual key system.

Portkey SDK Integration with Huggingface

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

1. Install the Portkey SDK

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

NodeJS

npm install --save portkey-ai

2. Initialize Portkey with the Virtual Key

To use Huggingface with Portkey, get your Huggingface Access token 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"]
    provider:"@PROVIDER", // Your Huggingface Virtual Key
    huggingfaceBaseUrl: "HUGGINGFACE_DEDICATED_URL" // Optional: Use this if you have a dedicated server hosted on Huggingface
})

3. Invoke Chat Completions with Huggingface

Use the Portkey instance to send requests to Huggingface. 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: 'meta-llama/Meta-Llama-3.1-8B-Instruct', // make sure your model is hot
});

console.log(chatCompletion.choices[0].message.content);

Using Virtual Keys

Virtual Keys serve as Portkey’s unified authentication system for all LLM interactions, simplifying the use of multiple providers and Portkey features within your application. For self-hosted LLMs, you can configure custom authentication requirements including authorization keys, bearer tokens, or any other headers needed to access your model:

1. Navigate to Virtual Keys in your Portkey dashboard
2. Click “Add Key” and enable the “Local/Privately hosted provider” toggle
3. Configure your deployment:
   • Select the matching provider API specification (typically OpenAI)
   • Enter your model’s base URL in the Custom Host field
   • Add required authentication headers and their values
4. Click “Create” to generate your virtual key

You can now use this virtual key in your requests:

NodeJS

const portkey = new Portkey({
    apiKey: "PORTKEY_API_KEY",
    provider:"@YOUR_SELF_HOSTED_LLM_PROVIDER"

async function main() {
  const response = await client.chat.completions.create({
    messages: [{ role: "user", content: "Bob the builder.." }],
    model: "your-self-hosted-model-name",
  });

console.log(response.choices[0].message.content);
})
