Installation

Usage

import { AnthropicVertex } from '@anthropic-ai/vertex-sdk';

// Additionally goes through the standard `google-auth-library` flow.
const client = new AnthropicVertex();

async function main() {
  const result = await client.messages.create({
    messages: [
      {
        role: 'user',
        content: 'Hey Claude!',
      },
    ],
    model: 'claude-3-sonnet@20240229',
    max_tokens: 300,
