Private AI vs ChatGPT Enterprise
Both let a team use AI at work with business controls. The main difference is where your prompts and documents are processed: on OpenAI's systems, or on hardware you own.
Last updated October 2026
What ChatGPT Enterprise offers
OpenAI's enterprise privacy page says it doesn't train its models on business data by default, that you own your inputs and outputs where allowed by law, and that workspace admins control how long data is retained. It also says deleted conversations are removed from its systems within 30 days unless it's legally required to keep them, and that authorized OpenAI employees only access conversations to resolve incidents, recover conversations with your permission, or where the law requires.
What private AI on your own hardware changes
With a private system, prompts and documents are processed on a machine you own, in your office. There's no AI provider holding your conversations, so retention and access follow your own policies. The system still uses the internet for software and model updates, and for remote management if you choose it.
When ChatGPT Enterprise is the better choice
- You want OpenAI's largest models, which can be stronger than local models at some tasks.
- You'd rather not have any hardware on site.
- Your team is spread across many locations and you're comfortable with OpenAI's terms.
When private AI fits better
- Your policies, clients or contracts make you want documents processed on hardware you control.
- You want one predictable setup that keeps working the same way whatever a provider changes.
- Your work is everyday drafting, summarizing and answering questions from your own documents, where local models are often a good fit.
