Portkey SDK Integration with Google Palm

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

​
1. Install the Portkey SDK

Add the Portkey SDK to your application to interact with Google Palm’s API through Portkey’s gateway. 
npm install --save portkey-ai

​
2. Initialize Portkey with Your AI Provider

Set up Portkey with your AI Provider slug. Add your Google Palm API key to Model Catalog to get the provider slug. 
import Portkey from 'portkey-ai'


const portkey = new Portkey({

    apiKey: "PORTKEY_API_KEY", // defaults to process.env["PORTKEY_API_KEY"]

    provider:"@google-palm-prod" // Your AI Provider slug from Model Catalog

})

​
3. Invoke Chat Completions with Google Palm

Use the Portkey instance to send requests to Google Palm. 
const chatCompletion = await portkey.chat.completions.create({

    messages: [{ role: 'user', content: 'Say this is a test' }],

    model: 'chat-bison-001',

});

console.log(chatCompletion.choices);

​
Managing Google Palm Prompts

You can manage all prompts to Google Palm in the Prompt Library. All the current models of Google Palm 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.
