NVIDIA rolls out Codex companywide

NVIDIA has rolled out OpenAI’s Codex across its workforce, giving more than 10,000 employees access to the GPT-5.5-powered agent for coding and other work. (nvidia.com) NVIDIA said the users span engineering, product, legal, marketing, finance, sales, human resources, operations and developer programs. The company said engineers had been using GPT-5.5 in Codex for several weeks before the broader deployment. (nvidia.com) Codex started as a coding tool, but OpenAI now describes it as an agent for complex coding, computer use, knowledge work and research workflows. OpenAI said GPT-5.5 became available in Codex on April 23, 2026. (openai.com 1) (openai.com 2) NVIDIA said the system runs on its GB200 NVL72 rack-scale servers. The company said those systems deliver 35 times lower cost per million tokens and 50 times higher token throughput per megawatt than prior-generation Hopper-based infrastructure. (nvidia.com) The company framed the rollout as more than a software-engineering story. NVIDIA said employees are using Codex for debugging, experiments, documentation, workflow automation and other tasks outside traditional coding teams. (nvidia.com) OpenAI is also pushing Codex deeper into large companies. Last week, it said Codex had reached 4 million weekly active users and launched Codex Labs with Accenture, Capgemini, CGI, Cognizant, Infosys, PwC and Tata Consultancy Services to help enterprises move from pilots to broader deployments. (openai.com) The NVIDIA deployment also extends a long partnership between the two companies. NVIDIA said that relationship began in 2016, when Chief Executive Jensen Huang delivered the first DGX-1 artificial-intelligence supercomputer to OpenAI’s San Francisco headquarters. (nvidia.com) For NVIDIA, the message is that Codex is no longer being pitched only as a coding assistant. The company is deploying it as a general workplace agent, and OpenAI is building the enterprise services to make that kind of rollout stick. (nvidia.com) (openai.com)
