LocalAI

Portkey provides a robust and secure gateway to facilitate the integration of various Large Language Models (LLMs) into your applications, including your locally hosted models through LocalAI.

​

Portkey SDK Integration with LocalAI

​

1. Install the Portkey SDK

npm install --save portkey-ai

​

2. Initialize Portkey with LocalAI URL

First, ensure that your API is externally accessible. If you’re running the API on http://localhost, consider using a tool like ngrok to create a public URL. Then, instantiate the Portkey client by adding your LocalAI URL (along with the version identifier) to the customHost property, and add the provider name as openai.

import Portkey from 'portkey-ai'

const portkey = new Portkey({
    apiKey: "PORTKEY_API_KEY", // defaults to process.env["PORTKEY_API_KEY"]
    provider: "openai",
    customHost: "https://7cc4-3-235-157-146.ngrok-free.app/v1" // Your LocalAI ngrok URL
})

3. Invoke Chat Completions

Use the Portkey SDK to invoke chat completions from your LocalAI model, just as you would with any other provider.

const chatCompletion = await portkey.chat.completions.create({
    messages: [{ role: 'user', content: 'Say this is a test' }],
    model: 'ggml-koala-7b-model-q4_0-r2.bin',
});

console.log(chatCompletion.choices);
