@prefactor/ai

Prefactor middleware integration for the Vercel AI SDK.

@prefactor/ai overview

@prefactor/ai connects Vercel AI SDK model calls to Prefactor tracing. It captures agent, model, and tool spans and sends them through your configured transport.

Use this package as a provider for the core init function.

Quick start

import { init } from '@prefactor/core';
import { PrefactorAISDK } from '@prefactor/ai';
import { generateText, wrapLanguageModel } from 'ai';
import { anthropic } from '@ai-sdk/anthropic';

const prefactor = init({
  provider: new PrefactorAISDK(),
  httpConfig: {
    apiUrl: 'https://app.prefactorai.com',
    apiToken: process.env.PREFACTOR_API_TOKEN!,
    agentIdentifier: 'chat-app-v1',
  },
});

const model = wrapLanguageModel({
  model: anthropic('claude-3-haiku-20240307'),
  middleware: prefactor.getMiddleware(),
});

const result = await generateText({
  model,
  prompt: 'Hello!',
});

await prefactor.shutdown();
