Nvidia Rolls Out GPT-5.5 Internally

- Nvidia deployed OpenAI’s code‑oriented tooling (reported as Codex/GPT‑5.5) to a large internal population to boost developer productivity and research workflows. - The company rolled the tools out to about 10,000 employees, using per‑agent dedicated VMs, a zero‑data‑retention policy and read‑only production access to limit risk. - The deployment is being cited as an example of enterprise guardrails for powerful models: capability plus strict permissioning and infrastructure isolation.
