This is a last-minute leak (though I guess this will be more of a teaser then) of GPT-5's coding capabilities from OpenAI. I tried to fix the site, but it's still a bit broken.

To view a demo, open the frame in a new tab and add gpt-5-coding-examples/ after githubcatw.github.io/.

As I'm writing this GPT-5 will be officially announced in around 8 minutes.

GPT-5 Coding Examples

This repository contains a curated collection of demo applications generated entirely in a single GPT-5 prompt, without writing any code by hand.

These demos were selected to showcase the model’s strengths in coding — especially quickly scaffolding websites, front-end applications, games, and interactive UIs from natural-language descriptions. They’re intended as inspiration for you to build your own ideas.

From there, you can view any example, see the zero-shot prompt that created the code, and remix it for your own ideas.

Build with GPT-5

If you want to experiment with similar prompts, you can try GPT-5 in your preferred coding environment:

• Codex CLI – A lightweight coding agent that runs in your terminal.
• Your favorite IDE or coding tool – Use GPT-5 within your existing workflow to generate and refine code.
• ChatGPT – Open ChatGPT and choose GPT-5 to generate and preview code in the browser.

Choose an example, copy its prompt for inspiration, and adapt it to your own needs.
Let GPT-5 build your idea, then iterate on the prompt or code to explore variations.

For Developers: Codex CLI

We recommend using the Codex CLI with GPT-5 for a seamless coding experience.

The Codex CLI runs in your terminal: given a prompt, it will generate code, execute it in a sandbox, and even preview the results live.

Example:

codex --model gpt-5 --full-auto "Build a simple photobooth application with camera access in a single HTML file"

GPT-5 will scaffold the app, write files, install dependencies as needed, and show a live preview. This is the go-to solution for developers who want to bootstrap apps or add features quickly.

You can also use GPT-5 with any other AI coding tool that supports the model.

For Non-Developers: ChatGPT

If you don’t have a coding environment, you can use ChatGPT (with GPT-5) to build and preview apps entirely in the browser:

1. Copy an example’s prompt for inspiration and customize it to make it your own.
2. Let GPT-5 generate the code (HTML/CSS/JavaScript).
3. Open it in Canvas preview to see it run live.
4. Download or copy the output HTML for real-world use.

With this method, anyone can create a working single-page app — no local setup required.
