Claude Haiku 4.5 is now available through Netlify’s AI Gateway — no extra setup required.

You can use the native Anthropic SDK without managing API keys or external accounts.

Here’s how to use it today in a Netlify Function with the Anthropic SDK:

import Anthropic from "@anthropic-ai/sdk";
export default async () => {
  const anthropic = new Anthropic();
  const response = await anthropic.messages.create({
    model: "claude-haiku-4-5-20251001",
    messages: [
      {
        role: "user",
        content: "Give me pros and cons of using claude-haiku-4-5-20251001 over other models."
      },
    ],
  });
}

This is supported across Edge, Background, and Scheduled Functions and includes features like Rate-Limiting, access to Netlify’s advanced caching primitives, and many others.
