Q: Is local ChatGPT GDPR-compliant?

Yes, when running in EU data centers with local models only. Opsily offers German hosting (EU-compliant). As long as you don't route queries to external APIs (ChatGPT, Claude), all data stays in the EU. If you want to use ChatGPT or Claude APIs occasionally, you'd need a DPA with those providers. Local-only setup is cleanest for GDPR.

Q: What happens if I want to stop using Opsily?

Your data is yours. Open WebUI stores conversations in a database you control. You can export chats as JSON or markdown. Migrate to another host anytime. No lock-in, no data extraction fees. If you self-host Open WebUI elsewhere, your setup continues unchanged.

Q: How many team members can use one instance?

Unlimited. One Opsily server can support hundreds of users with multi-user authentication and role-based access control. You're not paying per-seat like ChatGPT Plus ($20/user). Pay once for the server. Everyone logs in and uses the same instance.

Q: Do local models understand as much as ChatGPT-4?

No. Local models (Llama 2, Mistral) are smart but not as advanced as GPT-4. They handle most work well: summarizing, drafting, coding, customer support. But on complex reasoning or specialized tasks, GPT-4 pulls ahead. That's why Open WebUI supports both—use local models for everyday tasks and route complex work to ChatGPT if you want.

Q: Do I need technical skills to set up local ChatGPT?

Not with Opsily. We handle Docker, networking, and Ollama configuration. Click 'Install Open WebUI' and start chatting in 3 minutes. If you prefer command-line self-hosting, that's an option too—Open WebUI docs are excellent. Most non-technical users choose Opsily to avoid the setup headache.

Question 1

What's the difference between Ollama and Open WebUI?

Accepted Answer

Ollama is the engine—it downloads and runs local language models like Llama 2 and Mistral. Open WebUI is the front-end—the ChatGPT-like interface you interact with. Ollama does the thinking. Open WebUI makes it pretty and usable. You need both for a complete setup, but Opsily handles the technical wiring.

Question 2

Can I mix local models and ChatGPT/Claude in the same interface?

Accepted Answer

Yes. Open WebUI supports OpenAI-compatible APIs. You can route fast questions to Mistral 7B (local, instant) and complex queries to Claude (external API). Switch between models in the dropdown. Some teams use local models for brainstorming and external APIs for final polish.

Question 3

How fast are local LLMs compared to ChatGPT?

Accepted Answer

Speed depends on your server hardware and model size. Mistral 7B responds in 1-3 seconds. Llama 2 13B takes 5-10 seconds. ChatGPT is usually faster (< 1 second) because it runs on NVIDIA's massive clusters. But for most tasks—summarizing, drafting, brainstorming—local models are fast enough. And you control the hardware.
