I built a full Mac app overnight using OpenAI's new GPT-5.5 model. No code. Then I tested it head-to-head against Claude Opus 4.7 on 4 real tasks. The result was not close.
━━━━━━━━━━━━━━━━━━━━
OpenAI just launched GPT-5.5, their most intelligent model ever, along with a massive upgrade to Codex, their AI agent app. In this video, I break down everything you need to know about GPT-5.5, how it compares to Claude Opus 4.7, and the Mac app I built with it overnight without writing a single line of code.
What's inside:
What GPT-5.5 actually is and who should use it
