Question 1

Can I run a self hosted chatgpt for a company on my own server?

Accepted Answer

Yes, for many users it is actually superior. Open WebUI provides a near-identical user interface but adds features ChatGPT lacks, such as the ability to switch between different AI models (like Llama 3 or Claude via API) in the same thread. It also includes robust Retrieval Augmented Generation (RAG) for free, allowing you to upload entire document libraries and chat with them without the strict file limits found in SaaS versions.

Question 2

Is Open WebUI free to use and how to set up a private ChatGPT?

Accepted Answer

When you use ChatGPT, your data is processed on US-based servers and may be used to train future models unless you are on a specific Enterprise tier. Opsily hosts your Open WebUI instance on private, dedicated servers in Germany. We do not have access to your chat logs, and your data is never used for model training. This makes it suitable for law firms, medical researchers, and EU-based tech companies.

Question 3

What kind of hardware do I need for a self hosted chatgpt with RAG?

Accepted Answer

High-performance AI requires VRAM. While you can run small models on basic CPU servers, we recommend our specialized GPU-accelerated plans for a responsive experience. Our managed hosting removes the complexity of configuring NVIDIA drivers or Docker containers. We provision the right amount of resources so your team experiences low-latency chat even with large 70B parameter models.

Question 4

Can I use my existing OpenAI API key with Open WebUI?

Accepted Answer

Absolutely. One of the best ways to use Open WebUI is a 'Hybrid' approach. You can use free, local models for simple everyday tasks to save money, and then switch to the OpenAI or Anthropic API for highly complex reasoning tasks. All of this happens within the same interface, providing a unified experience for your team while keeping your API costs significantly lower than per-seat subscriptions.

Question 5

Who manages the updates for Open WebUI and Ollama?

Accepted Answer

Opsily handles the heavy lifting. The AI world moves fast, with new models and UI features released weekly. We manage the container updates and ensure your Ollama backend is running the latest versions. This allows your team to focus on using the AI tools rather than performing maintenance on the underlying Linux environment or Python dependencies.

Question 6

Is there a limit to how many users I can add?

Accepted Answer

Unlike ChatGPT Business which charges 25 to 30 dollars for every single user, Opsily does not charge per seat. You are paying for the underlying server resources. You can add 5 users or 50 users to your Open WebUI instance at no extra cost, provided your chosen server plan has enough CPU and RAM to handle the concurrent chat requests. This makes it the most cost-effective way to scale AI across an organization.

Question 7

How do I migrate my team's data to a self-hosted instance?

Accepted Answer

Migration is straightforward. Open WebUI supports standard data formats for importing chat histories and document collections. If you are moving from a standard ChatGPT setup, our support team can assist in setting up your initial 'Knowledge Bases' and user groups to ensure a smooth transition. Your team will find the interface so similar to ChatGPT that most require zero training to get started.
