Executive Summary
K3 Technology needed a private AI solution that didn't force a tradeoff between capability and security. Teams were paying for ChatGPT, Claude, and Gemini separately — and still couldn't get privacy, model choice, and custom workflows in one place.
HummingAgent built Private GPT: a self-hosted, multi-model AI platform that gives teams access to GPT, Claude, Gemini, Llama, Mistral, and 30+ more models — all in one interface, with full data privacy and workflows built around how each team actually works.
The Challenge
- •Teams locked into a single AI provider with no way to compare or switch models
- •Public AI tools (ChatGPT, Claude) offered no data privacy — conversations could train external models
- •Private AI solutions were limited to one model and lacked modern capabilities
- •AI had no memory — every conversation started from scratch with no business context
- •Generic chat interfaces didn't fit team-specific workflows or processes
- •Multiple AI subscriptions with overlapping costs and no unified platform
The Solution
Private GPT Multi-Model Platform
- ✓Access to GPT, Claude, Gemini, Llama, Mistral, and 30+ models from one interface
- ✓Full data privacy — corporate data never leaves the client's environment
- ✓Context-aware memory that retains clients, projects, pricing, and past decisions
- ✓Custom workflows and prompts shaped around each team's processes
- ✓Microsoft SSO with role-based access control for enterprise security
- ✓File and document upload with vector search for business context
Platform Features
- ✓Model switcher — change AI providers mid-conversation without losing context
- ✓Persistent memory across sessions — AI remembers your business
- ✓Custom prompt library built around team-specific workflows
- ✓Document and file context — ask questions against your own data
- ✓Admin controls — manage users, permissions, and model access
- ✓Usage analytics — see how your team is using AI
