The Ollama server does not include an interactive Web UI; pair it with a frontend such as Open WebUI if you want browser-based chat.\n\nIt supports many models, including Llama, Mistral, Gemma, and Qwen, and provides an API for applications and integrations. Local models run on your own hardware; cloud models require an internet connection.\n\n**Key Features:**\n- **Local model execution**: Run supported models on your own hardware\n- **Model management**: Pull, run, and manage models with the CLI or API\n- **API integration**: Connect other applications to the Ollama server\n- **Privacy options**: Keep inference local when using local models\n\n**Learn More:**\n- [Ollama Official Website](https://ollama.com/)\n- [Ollama GitHub Repository](https://github.com/ollama/ollama)\n- [Model Library](https://ollama.com/library)\n"
