I put GPT-5 through a practical test: a drawing app, a Python game, and a full website rebuild—then compared design quality and dev workflow vs. alternatives. You’ll see where GPT-5 shines, where it still stumbles, and how I pair it with tools like Magic Path for better UI.
Timestamps:
00:00 – GPT-5 launch, poem example, and claimed upgrades; why I’m testing coding + UI quality
01:37 – Build #1: drawing app (brush size, colors, undo/redo, export) → quick UI polish attempts
02:55 – Swapping to Magic Path for cleaner UI; code review/bug-fix tools in GPT-5
03:54 – One-click port to TypeScript/React; running the TS build
04:17 – Build #2: “Glow Cells Arena” (Pygame) with split/eject; fix flicker + growth on eat
06:45 – Build #3: law-firm website rebuild; GPT-5 (React/Tailwind) vs. Claude (HTML) results
07:50 – Takeaways + invite to Discord (daily live build vibes)
In this video I pressure-test GPT-5 with projects you might actually ship. We start with a simple drawing app prompt—brush thickness, colors, undo/redo, eraser, and export—and see GPT-5 produce a working tool on the first pass. The UI, while functional, feels generic, so I try quick refinement through the model and then contrast that with a one-shot design from Magic Path, which delivers a cleaner, more modern interface immediately. I also poke at GPT-5’s built-in developer helpers—code review, bug fixes, and language porting—and spin the project into a TypeScript/React version to check the DX.
Next, I raise the stakes with a Python clone of agar.io (“Glow Cells Arena”). GPT-5 scaffolds the project with configs, entities, camera logic, and SFX. After a quick round of fixes (removing flicker, ensuring the player grows when eating), the core loop plays well and keyboard actions like split/eject work as expected.
Finally, I test website generation on a real brief: rebuild a law firm site in the style/structure of a better reference. GPT-5 outputs React + Tailwind with a stronger visual system, while Claude’s baseline HTML version nails the context but feels less polished. The takeaway: GPT-5 is a legit step up for coding and multi-file projects, but pairing it with a dedicated design tool like Magic Path can save time and dramatically upgrade your UI.
