ChatGPT Enterprise AlternativePrivate AI. No Data Leaves Your Network.
Same conversational intelligence, document analysis, and content generation. No per-seat fees. No third-party data processing. AI that runs on your infrastructure with full compliance controls.
Why Businesses Leave ChatGPT Enterprise
Per-seat pricing, data privacy gaps, limited customization, and missing compliance certifications.
Data Leaves Your Control
Every prompt is processed on OpenAI infrastructure. For organizations handling CUI, PHI, or privileged communications, any third-party processing creates compliance gaps.
Per-Seat Costs Escalate
$60/user/month means $360,000/year for 500 users. Prices increase regularly. A private deployment has unlimited users with zero per-seat fees.
No Real Customization
Custom GPTs are not fine-tuning. You cannot train the underlying model on proprietary data or control inference parameters. Private AI gives you full architecture control.
Compliance Gaps
ChatGPT Enterprise lacks CMMC, FedRAMP, and ITAR certification. Not suitable for defense, government, or classified environments. Private deployment inherits your existing security controls.
PTG Private AI vs. ChatGPT Enterprise
$60/User/Month Recurring
100 users = $72,000/year. 200 users = $144,000/year. 3-year total for 100 users: $216,000+.
Data on OpenAI Servers
Prompts and responses processed on infrastructure you do not control, audit, or own.
GPT-4 Only
Limited to OpenAI's model catalog. No choice of architecture. Vendor controls versioning and deprecation.
One-Time Build, Unlimited Users
No per-seat fees. Cost per user drops as adoption grows across your organization.
Data Stays on Your Servers
Zero external transmission. Full audit logs. Your data, your hardware, your control.
Any Open-Source Model
Llama 3, Mistral, Qwen, DeepSeek. Full fine-tuning and RAG integration.

Frequently Asked Questions
Can open-source models match ChatGPT quality?
Yes. Llama 3.1 405B matches or exceeds GPT-4 on standard benchmarks. With fine-tuning on your data and RAG for document retrieval, private models outperform ChatGPT on your specific business tasks.
How much does switching from ChatGPT Enterprise save?
A 100-user organization paying $72,000/year for ChatGPT Enterprise can deploy private AI for a one-time investment. Break-even typically occurs within 12-18 months with significant savings after that.
Is private AI HIPAA compliant?
Yes. On-premise deployment means no BAA needed with a third party for the AI layer itself. We build HIPAA technical safeguards into the architecture. See our HIPAA compliance services.
Can our employees use it the same way they use ChatGPT?
Yes. We deploy a web-based chat interface identical in function to ChatGPT. Document upload, conversation history, and team workspaces are all included. The experience is familiar from day one.
What about ongoing support?
Every deployment includes 90 days of post-deployment support. Ongoing support plans cover model updates, performance monitoring, retraining, and scaling as your usage grows.
