Private ChatGPT for business
Last updated
A private ChatGPT for business is a chat assistant that runs on your own server, so prompts and files are not sent to an AI provider. A common setup is Ollama plus Open WebUI on a GPU box such as Olares One.

What do you get, and what do you give up?
A chat assistant on your own server looks and works much like ChatGPT. Staff type a question or attach a file in a browser and get an answer. The model runs on company hardware, so neither the prompt nor the file is sent to an AI provider for processing.
Open models do the work. They handle drafting, summaries and questions about documents. On the hardest reasoning tasks the largest cloud models are usually stronger, and that gap is the main thing you give up. Try your own tasks before rollout.
Which parts does a private ChatGPT for business need?
A working setup needs a machine with enough GPU memory, a model runner such as Ollama, a chat front end such as Open WebUI and one account per person. It also needs backups, because chats and uploaded files become business data that someone has to protect.
Memory is the part people get wrong. By an approximate rule of thumb, a 4-bit model needs about 0.5-0.6 GB per billion parameters plus a few GB for context. That puts a 14B model near 9 GB and a 32B model near 19-20 GB. The self-hosted ChatGPT alternative guide compares the software.
How does it run on Olares One?
Olares One puts these parts in one box. Olares Market lists Ollama and Open WebUI as one-click installs. Its RTX 5090 Mobile has 24 GB of VRAM, according to Olares' spec page. Each person gets a separate account through the LarePass app, and encrypted backups are built into Olares OS.
In Olares' own test, the box ran qwen3-30b-a3b at 157 tokens/s for one request and about 81 tokens/s per request with 8 concurrent requests. Your speed will depend on the model and on prompt length. Olares says the cost works out to 27.7 USD per user per month, assuming 4,999 USD of hardware shared by 5 users over 3 years. That figure covers hardware only.
Should a small business start here?
Yes, in our view, if most of the work is drafting, summaries and questions about documents, and the load stays near the 8 concurrent requests Olares tested. If the business depends on top-tier reasoning, a local model may fall short, and we would test much harder before buying.
Plan for the limits. Activation and Olares Market need internet, so set up while online. Models above 24 GB slow down because part of the model moves to system memory. There is one box, so plan backups. If staff work remotely, read what leaves a private AI server.
Questions & answers
Is a private ChatGPT as good as ChatGPT?
Open models that fit in 24 GB of VRAM handle drafting, summaries and document questions. The largest cloud models are usually stronger on hard reasoning. Test with your own tasks.
Can staff use a private ChatGPT from home?
Yes, if you allow it. Olares One offers secure remote access with a built-in VPN. If the box is kept fully offline, staff can reach it only on the local network.
