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.
Key facts
- The GPT-5.5 launch and the Codex rollout reflect more than 10 years of collaboration between NVIDIA and OpenAI
- Over 10,000 NVIDIANs — across engineering, product, legal, marketing, finance, sales, HR, operations and developer programs — are already using GPT-5.5-powered Codex to achieve, in their words
- NVIDIA engineers have had access to GPT-5.5 through the Codex app for a few weeks, and the gains are measurable
- OpenAI has committed to deploying more than 10 gigawatts of NVIDIA systems for its next-generation AI infrastructure — a buildout that will put millions of NVIDIA GPUs at the foundation of OpenAI’s
Summary
Codex, OpenAI’s agentic coding application, is enabling this new frontier. Over 10,000 NVIDIANs — across engineering, product, legal, marketing, finance, sales, HR, operations and developer programs — are already using GPT-5.5-powered Codex to achieve, in their words, “mind-blowing” and “life-changing” results. NVIDIA engineers have had access to GPT-5.5 through the Codex app for a few weeks, and the gains are measurable. Debugging cycles that once stretched across days are closing in hours.
