Gemma 4 is Google DeepMind's latest open-weight AI model, and this tutorial shows complete beginners how to run it locally in under an hour. You'll install Ollama, download the Gemma 4 model, and build three Python apps: a Q&A tool, a chatbot with memory, and an image analyzer, all running privately on your own machine with no cloud, no GPU, and no prior AI experience required.
