Private AI vs ChatGPT
Private AI runs on your infrastructure with your data — giving accurate, business-specific answers without sharing anything externally. ChatGPT is a public model with broad general knowledge, but no access to your business context, and all prompts pass through OpenAI's systems.
The core difference is data and specificity. ChatGPT was trained on public internet data. It can explain what a RAG system is, write a generic sales email, or summarise a document. What it cannot do is tell you why your Q3 revenue is down, which of your customers are most likely to churn, or what your standard labour rate is for a specific trade. It has no access to your data.
Private AI solves this by building a language model system trained on — or connected to — your specific business data. When a staff member asks the AI why a project went over budget, it can look at your actual project history. When a sales rep asks for the best approach for a specific customer segment, it references your actual sales data.
The privacy dimension matters too. Every prompt you send to ChatGPT passes through OpenAI's servers. For general tasks this may be acceptable. For questions involving customer data, pricing strategy, or confidential business processes, it is not. Private AI keeps every query within your infrastructure.
