​
Overview

The Vercel AI SDK works seamlessly with Adaptive through two methods:
  • Adaptive Provider (Recommended): Use the native @adaptive-llm/adaptive provider for built-in support.
  • OpenAI Provider: Use Adaptive via @ai-sdk/openai with a custom base URL.

​
Method 1: OpenAI Provider

​
Installation

npm install ai @ai-sdk/openai

​
Configuration

import { openai } from "@ai-sdk/openai";

const adaptiveOpenAI = openai({
  apiKey: process.env.ADAPTIVE_API_KEY,
  baseURL: "https://llmadaptive.uk/api/v1",
});

​
Usage

import { generateText } from "ai";

const { text } = await generateText({
  model: adaptiveOpenAI(""), // Empty string enables intelligent routing
  prompt: "Explain quantum computing simply",
});

​
Method 2: Adaptive Provider

​
Installation

npm install @adaptive-llm/adaptive

​
Basic Setup

import { adaptive } from "@adaptive-llm/adaptive";

// Or customize:
import { createAdaptive } from "@adaptive-llm/adaptive";

const customAdaptive = createAdaptive({
  baseURL: "https://llmadaptive.uk/api/v1",
  apiKey: process.env.ADAPTIVE_API_KEY,
  headers: {
    "User-Agent": "MyApp/1.0",
  },
});

​
Generating Text

import { generateText } from "ai";

const { text } = await generateText({
  model: adaptive(),
  prompt: "Write a vegetarian lasagna recipe for 4 people.",
});

​
Streaming Example

import { streamText } from "ai";

const { textStream } = await streamText({
  model: adaptive(),
  prompt: "Explain machine learning.",
});

for await (const delta of textStream) {
  process.stdout.write(delta);
}

​
Provider Options

await generateText({
  model: adaptive(),
  prompt: "Summarize this article",
  providerOptions: {
    costBias: 0.8, // Value from 0 to 1, higher = prioritize cost savings
  },
});

​
Tool Use Example

import { generateText, tool } from "ai";
import { z } from "zod";

const { text } = await generateText({
  model: adaptive(),
  prompt: "What's the weather in New York?",
  tools: {
    getWeather: tool({
      description: "Get weather for a location",
      parameters: z.object({
        location: z.string(),
      }),
      execute: async ({ location }) => {
        return `Weather in ${location} is sunny and 72°F`;
      },
    }),
  },
});
