First download Ollama for your operating system. Choose a model (start with 1b; use smaller ones if your computer struggles, 7b is ideal for most consumer hardware). Install the model by copying the install command. You can interact with the model via command line, but it’s better to use a text editor with AI integration like Zed (Mac/Linux) or Visual Studio Code (Windows/Linux/Mac), with an extension like Copilot. With these editors, you can chat with the model and insert generated code directly. You don’t need any paid services everything works offline on your PC.
