      "question": "What are the system requirements for Open-WebUI and Ollama?",
      "answer": "Running Open-WebUI connected to an Ollama backend engine requires a 64-bit Linux or macOS system with at least 8 GB RAM for 3B models, 16 GB+ RAM for 7B–8B models, 10 GB SSD storage, and Docker Engine 24.0+ installed. Before deploying Open-WebUI, verify system hardware and software prerequisites: **Operating System:** Ubuntu 24.04 LTS, 22.04 LTS, Debian 12, or macOS"

    {
      "question": "How do you install Ollama on the host system?",
      "answer": "To install Ollama on Ubuntu or Linux, run curl -fsSL https://ollama.com/install.sh | sh in terminal and verify the service daemon is active on port 11434. Open-WebUI requires an active Ollama instance to serve LLM inferences."
    },
    {
      "question": "How do you install Open-WebUI using Docker?",
      "answer": "To install Open-WebUI using Docker, run the official container image from GitHub Container Registry (ghcr.io/open-webui/open-webui:main), mapping host port 3000 to container port 8080 and connecting to the Ollama backend API. Deploying Open-WebUI via Docker ensures isolated dependencies and simple updates."
    },
    {
      "question": "How do you configure Open-WebUI and create an Admin account?",
      "answer": "To configure Open-WebUI, navigate to http://localhost:3000 in your web browser and sign up for an initial account, which automatically receives Super Admin permissions. Once the container is active, configure your local web workspace:"

    {
      "question": "Is Open-WebUI completely free and open source?",
      "answer": "Yes. Open-WebUI is 100% open-source software licensed under the MIT License. It does not require any paid subscription or external cloud API key."
    },
    {
      "question": "How do I pull new Ollama models inside Open-WebUI?",
      "answer": "Navigate to **Admin Settings** > **Models** inside the Open-WebUI interface. Type any model tag from the Ollama Library (e.g. mistral, gemma2, codellama) into the **Pull a model** field and click the download button."
    },
    {
      "question": "How do I update Open-WebUI to the latest version?",
      "answer": "To update your Docker container to the newest release, pull the latest image and restart:"
    },
    {
      "question": "Can multiple users access my self-hosted Open-WebUI instance?",
      "answer": "Yes. Open-WebUI includes full multi-user authentication. Super Admins can invite team members, set model permission controls, or restrict access via role assignments in **Admin Panel** > **Users**. ---"

  "semanticFactualBody": "Open-WebUI (formerly Ollama WebUI) is an extensible, self-hosted web interface designed for managing and interacting with local large language models. Featuring a user interface similar to ChatGPT, Open-WebUI provides multi-user management, Retrieval-Augmented Generation (RAG) document uploading, web search integration, custom system prompt templates, voice chat, and code execution. Connecting Open-WebUI to an **Ollama** backend engine on Ubuntu 24.04 LTS (Noble Numbat) or 22.04 LTS creates a 100% private, offline AI workspace that executes open-weight models (Llama 3.2, Qwen 2.5, Mistral, Gemma 2) directly on your local CPU or GPU hardware without third-party API costs or data tracking. *Last updated: July 24, 2026* --- What are the system requirements for Open-WebUI and Ollama? Running Open-WebUI connected to an Ollama backend engine requires a 64-bit Linux or macOS system with at least 8 GB RAM for 3B models, 16 GB+ RAM for 7B–8B models, 10 GB SSD storage, and Docker Engine 24.0+ installed. Before deploying Open-WebUI, verify system hardware and software prerequisites: **Operating System:** Ubuntu 24.04 LTS, 22.04 LTS, Debian 12, or macOS **Memory:** Minimum 8 GB RAM for running 3B models; 16 GB+ RAM recommended for 7B–8B models **Disk Storage:** 10 GB SSD space for model weights and RAG vector databases **Prerequisites:** Docker Engine 24.0+ and Ollama 0.1.30+ installed --- How do you install Ollama on the host system?
