Anthropic’s Claude Haiku 5.5 model is now available through Netlify’s AI Gateway and Agent Runners with zero configuration required.

Use the Anthropic SDK directly in your Netlify Functions without managing API keys or authentication. AI Gateway handles everything automatically. Here’s an example using Claude Haiku 5.5 with the Messages API:

import Anthropic from '@anthropic-ai/sdk';

export default async () => {
    const anthropic = new Anthropic();

    const response = await anthropic.messages.create({
        model: 'claude-haiku-5-5',
        max_tokens: 1024,
        messages: [
            { role: 'user', content: 'Give a concise explanation of how AI works.' }
        ],
    });

    return Response.json(response);
};

Claude Haiku 5.5 is also available across Scheduled Functions, Background Functions, and Edge Functions. You get automatic access to Netlify’s caching, rate limiting, and authentication infrastructure.
