OpenAI’s GPT-5.5 Instant model is now available through Netlify’s AI Gateway with zero configuration required.

Use the OpenAI SDK directly in your Netlify Functions without managing API keys or authentication. The AI Gateway handles everything automatically. Here’s an example using the GPT-5.5 Instant model:

import OpenAI from 'openai';
export default async () => {
    const openai = new OpenAI();
    const response = await openai.responses.create({
        model: 'chat-latest',
        input: 'How does AI work?'
    });
    return Response.json(response);
};

Note: The model API name is chat-latest.

GPT-5.5 Instant is available for all Function types. You get automatic access to Netlify’s caching, rate limiting, and authentication infrastructure.
