Vibe Coding With GPT 5.3 Codex

Description

In this video, I am putting the newly released GPT 5.3 Codex to the ultimate test in a new benchmark I am calling BridgeBench. I put GPT 5.3 Codex through the ringer with a series of complex one-shot prompts, ranging from building a full Windows 10 interface clone to coding a functional FPS game and a Flight Simulator from scratch. I also break down the official benchmarks released by OpenAI. While GPT 5.3 Codex shows massive improvements in the Terminal Bench 2.0 (77.3%) and OS World Verified (Computer Use), the SWE-Bench coding score only saw a 0.4% increase. Is this model a revolution or just a slight iteration? I give my honest review after hours of testing. The Grind: 👍 Like Goal: 200 Likes.
