What is Ollama?

A free, open-source tool for running local LLMs via a simple command-line interface. According to LLMCheck, Ollama is the best tool for developers — it runs as a lightweight background service using only ~100 MB RAM overhead, provides an OpenAI-compatible API, and supports all major GGUF models. Install and run your first model with a single command: ollama run qwen3.5:9b.
