You can use Vercel AI SDK to interact with FriendliAI. This makes migration of existing applications already using Vercel AI SDK particularly easy.

​
How to use

Before you start, ensure you’ve already obtained the FRIENDLI_TOKEN from the Friendli Suite. 
npm i ai @friendliai/ai-provider

​
Instantiation

Instantiate your models using a Friendli provider instance. We provide usage examples for each type of endpoint. Choose the one that best suits your needs: 
import { friendli } from '@friendliai/ai-provider';

// Automatically select serverless endpoints
const model = friendli("meta-llama-3.3-70b-instruct");

// Or specify a specific serverless endpoint
const model = friendli("meta-llama-3.3-70b-instruct", {
  endpoint: "serverless",
});

​
Example: Generating text

Generate a response with the generateText function: 
import { friendli } from "@friendliai/ai-provider";
import { generateText } from "ai";

const { text } = await generateText({
  model: friendli("meta-llama-3.3-70b-instruct"),
  prompt: "Write a vegetarian lasagna recipe for 4 people.",
});

console.log(text);

​
Example: Using Enforcing Patterns (Regex)

Specify a specific pattern (e.g., CSV), character sets, or specific language characters (e.g., Korean Hangul characters) for your LLM’s output. 
import { friendli } from "@friendliai/ai-provider";
import { generateText } from "ai";

const { text } = await generateText({
  model: friendli("meta-llama-3.3-70b-instruct", {
    regex: new RegExp("[\n ,.?!0-9\uac00-\ud7af]*"),
  }),
  prompt: "Who is the first king of the Joseon Dynasty?",
});

console.log(text);

​
Example: Using built-in tools

This feature is in Beta and available only on the Serverless Endpoints.
Using tool assisted chat completion API, models can utilize built-in tools prepared for tool calls, enhancing its capability to provide more comprehensive and actionable responses. Available tools are listed here. 
import { friendli } from "@friendliai/ai-provider";
import { streamText } from "ai";

const result = await streamText({
  model: friendli("meta-llama-3.3-70b-instruct", {
    tools: [
        {"type": "web:search"},
        {"type": "math:calculator"},
    ],
  }),
  prompt: "Find the current USD to CAD exchange rate and calculate how much $5,000 USD would be in Canadian dollars.",
});

for await (const textPart of result.textStream) {
  console.log(textPart);
}

​
OpenAI Compatibility

You can also use @ai-sdk/openai as the APIs are OpenAI-compatible. 
import { createOpenAI } from '@ai-sdk/openai';

const friendli = createOpenAI({
  baseURL: 'https://api.friendli.ai/serverless/v1',
  apiKey: process.env.FRIENDLI_TOKEN,
});
If you are using dedicated endpoints 
import { createOpenAI } from '@ai-sdk/openai';

const friendli = createOpenAI({
  baseURL: 'https://api.friendli.ai/dedicated/v1',
  apiKey: process.env.FRIENDLI_TOKEN,
});
