Nvidia rolls out OpenAI’s Codex AI agent to all employees

Nvidia has rolled out OpenAI’s Codex AI agent, powered by the GPT-5.5 model, to its entire workforce, according to an internal email from chief executive Jensen Huang.

Huang said Codex is now available to all employees after early access was given to around 10,000 staff across functions such as engineering, product, legal, marketing and sales.



“OpenAI’s Codex, powered by GPT-5.5, has launched and is available to every NVIDIAN,” Huang wrote in the email. He added that employees who tested the system reported strong results, with some calling it “mind-blowing” and “life-changing”.

Codex is an AI agent designed to assist with tasks such as coding, planning and workflow execution.

Nvidia said it is being used beyond software teams, including business and operations functions. Huang said the system runs on Nvidia’s Blackwell infrastructure and reflects closer collaboration with OpenAI.

“Codex runs on Nvidia… trained on Nvidia Blackwell, inferencing on Nvidia AI infrastructure,” he wrote.

OpenAI chief executive Sam Altman confirmed the rollout in a post on X, saying the companies tested deploying Codex across an entire organisation.


OpenAI president Greg Brockman said the company is exploring similar deployments with other enterprises.

Nvidia has also set up a Codex Lab with OpenAI to support internal adoption, with training sessions planned for employees in the coming weeks.

The development comes shortly after OpenAI’s coding assistant Codex crossed over four million weekly developers. The company added one million users in two weeks after reporting a three million count earlier this month.

To deepen Codex’s enterprise integration, the San Francisco-based company launched Codex Labs this month, a hands-on programme where its Codex experts work directly with organisations.

Seven global systems integrators (GSIs), including Accenture, Capgemini, Cognizant, Infosys and Tata Consultancy Services (TCS) have already enrolled.
