Description: Want to run large language models locally without sending your data to the cloud? In this video, I show you exactly how to run powerful LLMs on NVIDIA Spark using Open WebUI and Ollama — completely private and hosted on your own hardware.

We walk step-by-step through setting up Open WebUI with Ollama using NVIDIA Sync and Docker, pulling models like LLaMA 70B, DeepSeek, GPT-OSS 20B, and Qwen, and configuring everything so it runs smoothly on an enterprise-class GPU. You’ll see how to install the container, configure ports, create an admin account, download models, and switch between them — all without relying on ChatGPT or any external cloud service.

I also cover real-world expectations like first-run delays, GPU memory usage, slower inference trade-offs, and how to update or stop containers to reclaim resources. By the end, you’ll have a fully private, local AI assistant capable of running surprisingly large models right at home.

If you care about data privacy, self-hosted AI, or running LLMs locally, this setup is one of the easiest and most powerful ways to get started.

👍 If this helped, like the video, subscribe, and drop a comment with models or features you’d like me to test next.

CODE SNIPPET For Custom

!/usr/bin/env bash

set -euo pipefail

NAME="open-webui" IMAGE="ghcr.io/open-webui/open-webui:ollama"

cleanup() { echo "Signal received; stopping ${NAME}…" docker stop "${NAME}" >/dev/null 2>&1 || true exit 0 } trap cleanup INT TERM HUP QUIT EXIT

Ensure Docker CLI and daemon are available

if ! docker info >/dev/null 2>&1; then echo "Error: Docker daemon not reachable." >&2 exit 1 fi

Already running?

if [ -n "$(docker ps -q --filter "name=^${NAME}$" --filter "status=running")" ]; then echo "Container ${NAME} is already running." else # Exists but stopped? Start it. if [ -n "$(docker ps -aq --filter "name=^${NAME}$")" ]; then echo "Starting existing container ${NAME}…" docker start "${NAME}" >/dev/null else # Not present: create and start it. echo "Creating and starting ${NAME}…" docker run -d -p 12000:8080 --gpus=all \ #i added this for spped testing -e PYTORCH_CUDA_ALLOC_CONF=expandable_segments:True \ -e CUDA_VISIBLE_DEVICES=0 \ -e NVIDIA_TF32_OVERRIDE=0 \ -e COMMANDLINE_ARGS="--precision fp16" \ #halves VRAM usage, much faster than FP32 #end of test -v open-webui:/app/backend/data \ -v open-webui-ollama:/root/.ollama \ --name "${NAME}" "${IMAGE}" >/dev/null fi fi

echo "Running. Press Ctrl+C to stop ${NAME}."

Keep the script alive until a signal arrives

while :; do sleep 86400; done
