GPT-5-Codex: Wireframe to Real App Conversion

gpt-5-codex is a new model from OpenAI that is finetuned for coding, especially for front-end. Considering that front-end coding is my least favorite, I’ll likely use this for some upcoming projects. It’s building some non-trivial apps here, from scratch and also from wireframes.

"I have this wireframe, can you convert it to a real app for me? Generate HTML / inline CSS code for this website. Include CDN links for Tailwind / Bootstrap etc. Save your output to a file called index.html in the container's current directory." pic.twitter.com/ZdSBjmx0GA
