Private AI vs Grok for Business
Grok's business plans and API come with enterprise data terms. Grok is made by xAI, which its website now presents as SpaceXSI. The main difference from a private system is where your prompts and documents are processed: on the provider's systems, or on hardware you own.

What the provider says about training
The Enterprise FAQ on x.ai says it doesn't use business data, including prompts and answers, to train its models, and that in some cases it may offer free credits in exchange for permission to train on your business data. The Grok Business page lists no training as a feature of its Business and Enterprise plans.
What it says about retention and review
The same FAQ says inputs and outputs are automatically deleted within 30 days unless otherwise agreed in writing, or unless the provider is legally required to keep them, for example when they're flagged as possibly violating its terms. It says automated classifiers and safety tools may be used, and that a limited number of authorized staff may review data when legally required, such as when investigating security incidents or misuse.
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 Grok is the better choice
- You want the provider's latest models and features such as real-time search, voice and image generation.
- You want AI connected to the business apps your team already uses.
- You'd rather not have any hardware on site, and you're comfortable with the provider's terms.
When private AI fits better
- Your policies, clients or contracts make you want documents processed on hardware you control.
- You want retention decided only by your own policies.
- Your work is everyday drafting, summarizing and answering questions from your own documents.
