## FAQ

**What makes an AI model "private"?**  
Private models can run on your infrastructure, never train on your prompts, or offer contractual zero-data-retention. Open-weight models you host yourself give the strongest control.

**Can I run DeepSeek R1 on my own hardware?**  
Yes. It is open-weight under an MIT-style license. Quantized versions run on a single high-end GPU.

**Is Claude Enterprise the same as Claude.ai?**  
No. Claude Enterprise adds SSO, admin controls, larger context, and a contractual promise that Anthropic will not train on your data.

**How do I choose between open-source and hosted private AI?**  
Open-source wins for air-gapping or custom fine-tunes. Hosted private offerings win for uptime, compliance certifications, and less ops overhead.
