OpenAI’s New GPT-5.5 Powers Codex on NVIDIA Infrastructure — and NVIDIA Is Already Putting It to Work
TL;DR
AI agents have revolutionized developer workflows, and their next frontier is knowledge work: processing information, solving complex problems, coming up with new ideas and driving innovation. Codex, OpenAI’s agentic coding application, is enabling this new frontier. It’s now powered by GPT-5.5, OpenAI’s latest frontier model, which runs on NVIDIA GB200 NVL72 rack-scale systems. Over 10,000 […].
Nauti's Take
GPT-5.5 powering Codex is a concrete step toward autonomous developer workflows — the productivity gains for engineering teams could be substantial. The concern is hardware dependency: GB200 NVL72 systems aren't cheap or widely accessible, meaning the competitive advantage stays with well-capitalized players.
Worth watching how open-source alternatives respond.
