FAQ
What are the PC requirements?
Minimum 8GB RAM & modern CPU. For GPU setup, a compatible NVIDIA GPU with 6GB+ VRAM is recommended.
Can I use the AI offline after setup?
Absolutely! Once installed, you can run the models offline from your WebUI.
Can I request a specific model like Mistral or Orca?
Yes! I’ll check if your system can support it and install accordingly.
Will this work on macOS or Linux?
This service is mainly for Windows. Contact me before ordering if you're using Linux or Mac.
What kind of documents can I use to train the LLM?
You can use PDFs, DOCX, TXT, MD, CSV, and more. The AI will be able to chat, search, and summarize from your files.
Is web scraping legal and safe?
Web scraping depends on the website's terms and your use case. I’ll help configure scraping only from public or allowed sources, like blogs, wikis, or documentation sites.
What models can I use?
Any Ollama supported model like LLaMA, Mistral, Gemma, Phi, and more.
Can I get custom branding?
Yes! That’s included in the Silver and Gold stacks.
