How to Set Up Ollama and Run Your First Local AI Model

## What you will need A computer with at least 8GB RAM, a stable internet connection, and about 15 minutes. ## Step 1: Install Ollama Download Ollama from the official website for your OS and run the installer. ## Step 2: Open your terminal Terminal on macOS/Linux, Command Prompt/PowerShell on Windows. ## Step 3: Pull your first model Type `ollama run llama3` and press enter. It downloads automatically. ## Step 4: Start chatting Type directly to the model. Everything runs locally, nothing is sent anywhere. ## Step 5: Try different model sizes Smaller models run faster; larger models are more capable but need more RAM. ## Step 6: Use the local API (optional) Ollama exposes a local API that other tools like Open WebUI can connect to. ## Troubleshooting Slow responses usually mean underpowered hardware for that model size — try smaller. Failed downloads can be resumed. ## What to try next Explore Ollama's model library for coding-focused or larger models, or pair it with Open WebUI for a chat-app interface.
