I Tested Gpt 5 5 Vs Claude Opus 4 7

OpenAI just dropped GPT 5.5. They’re calling it a new class of intelligence for real work and powering agents. I ran the same prompt I gave Claude Opus 4.7 last week, a 3D interactive design system viewer built in Three.js, and compared the output. No cherry-picking. No sponsored angle. Just the honest side by side for designers, product managers, and engineers who need AI that actually ships work.. . GPT 5.5 brings tool-grounded self-verification, 400K context in Codex, 1M context in the API, and state-of-the-art scores on Terminal-Bench 2.0, OSWorld, and GDPval. OpenAI says it matches GPT 5.4 per-token latency while outperforming it across the board. But benchmarks and reality aren’t the same thing. In this video I break down what OpenAI actually claimed, what GPT 5.5 delivered on my real prompt, and how it compares to Opus 4.7 on the work designers and builders actually do.. . 🔗 Related videos.
