### The Advancement of Vibe Coding with GPT-5
My previous coworker Parker Ortolani has been exploring “vibe coding” for several months, creating native and web applications by guiding large language models with meticulously crafted prompts. Both GPT-4o and Claude aided him in developing functional prototypes, but GPT-5 is the initial model that provides the comprehensive experience he has been anticipating. Here’s how GPT-5 enhances previous models:
#### What Distinguishes GPT-5 for Vibe Coding
Parker mentions in his blog post:
> “The great part is that GPT-5 is simply outstanding. Not only does it autonomously create beautiful user interfaces without needing direction, it has also proven to be significantly more dependable. […] I am truly amazed at the speed with which I can now vibe code iOS and macOS applications.”
Elaborating on this, GPT-5’s most significant advancement for vibe coding lies in design quality and dependability. Previous models like GPT-4o and Claude could generate functional app frameworks, but the user experience frequently lacked refinement and a design-centric approach. They required extensive prompting to appear polished, and builds often encountered bugs introduced by the model itself.
In contrast, GPT-5 generates appealing, coherent interfaces without specific design direction and, according to Parker’s observations, has yet to cause any build errors in Xcode.
It is also faster and more proficient in resolving complex challenges. While GPT-4o might need several prompts to address technical problems, GPT-5 can resolve them nearly instantly, like enabling local AI models to parse an open webpage in his macOS browser project.
GPT-5 is additionally more reliable and adaptable. It can produce complete and diverse projects from a single prompt, including native applications, web simulations, games, and more.
#### My Personal Experience with GPT-5 Coding
For my part, using GPT-5 with ChatGPT communicating directly with Xcode has been equally revolutionary. For the first time, I’m creating more than just a simple sticker pack. I’ve named my current project LaunchBay.
It serves as a personal substitute for Apple’s Launchpad now that the new Spotlight is taking over in macOS Tahoe. It’s not intended for release (at least not yet), but it has been fantastic starting with no coding background, achieving a functional build, and adjusting it entirely through everyday language instructions.
Looking forward, 9to5Mac was the first to report that ChatGPT integration with Siri and Apple Intelligence will be upgraded from GPT-4o to GPT-5 in iOS 26.
