GPT-5 Pro is now available through Netlify’s AI Gateway — no extra setup required. You can use the OpenAI SDK directly, without needing to manage API keys or external accounts.

Here’s how you can use it today in Netlify Functions:

import { OpenAI } from "openai";
export default async () => {
  const openai = new OpenAI();
  const response = await openai.responses.create({
    model: "gpt-5-pro",
    input: "Give pros and cons of using GPT-5 Pro over open 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.

See more in the AI Gateway docs.
