Top Recommended Replacements
Llama 3 (via Ollama)
FREEBest Privacy Alternative
Why we like it
The model runs locally on your hardware; absolutely zero data leaves your premise; Llama 3 (70B) rivals GPT-4 in reasoning capabilities; free for commercial use (up to huge limits).
Keep in mind
Requires GPU hardware (e.g., NVIDIA A100s or Mac Studio) to run fast; knowledge cutoff is static unless you build RAG.
Open WebUI
FREEBest Interface Swap
Why we like it
A feature-rich, open-source clone of the ChatGPT interface; connects to your local Ollama models; supports 'Workspaces', document uploads (RAG), and multi-user management just like ChatGPT Enterprise.
Keep in mind
You have to host it yourself (Docker container).
Claude Team (Anthropic)
Best for Coding/Writing
Why we like it
Often preferred by developers for its massive 200k context window and superior coding logic; 'Projects' feature allows you to upload whole codebases for context; cheaper than ChatGPT Enterprise.
Keep in mind
Still a SaaS (data leaves your network), though they claim strict privacy on Team plans.
LibreChat
FREEBest 'All-in-One' UI
Why we like it
The ultimate aggregator; lets you switch between GPT-4, Claude 3, and Local Llama in one chat window; you pay only for the API usage (pennies) rather than a flat $20/$60 seat; supports plugins and file search.
Keep in mind
Requires setting up your own API keys.
Azure OpenAI Service
Best for Microsoft Shops
Why we like it
If you are already on Azure, this gives you the exact same GPT-4 models but inside your existing private cloud compliance boundary; easier procurement than signing a new contract with OpenAI.
Keep in mind
Interface is for developers (API), not a chat UI for end-users (unless you build one).
Hugging Face Chat (Privacy)
FREEBest Open SaaS
Why we like it
A hosted chat interface for open models (Llama 3, Mixtral, Qwen); 'Enterprise Hub' allows you to deploy private containers of these models easily.
Keep in mind
Less polished UI than OpenAI.
