Parker Ortolani, a developer, has been experimenting with “vibe coding” using large language models like GPT-4o and Claude. However, the latest GPT-5 model promises to deliver a complete experience he’s been waiting for. GPT-5 improves on earlier models in several ways.
According to Parker, GPT-5 is more reliable and efficient. It can design beautiful user interfaces without explicit guidance and has not caused any build errors in Xcode so far. The model is also quicker and more capable when solving complex problems. For instance, it can fix technical issues instantly, like enabling local AI models to parse open web pages.
GPT-5 is also more dependable and versatile. It can produce complete projects from a single prompt, including native apps, web simulations, games, and more. Parker has had a transformative experience with GPT-5, building a personal project called LaunchBay, which is a replacement for Apple’s Launchpad.
The integration of ChatGPT with Xcode is also set to upgrade from GPT-4o to GPT-5 in iOS 26, as reported by 9to5Mac. This development has the potential to revolutionize vibe coding and make it more accessible to developers.
