Ollama is a tool that allows users to run large language models (LLMs) locally on their machines without relying on cloud services. This ensures greater privacy, data control, and offline usage capabilities.

• Local Model Execution: Install and run AI models directly on your device, such as Llama 3.3, DeepSeek-R1, Phi-4, Mistral, and Gemma 2.
• Cross-Platform Compatibility: Available for macOS, Linux, and Windows, making it accessible on multiple environments.
• Command Line Interface (CLI): Operates through the terminal or command prompt, offering efficient interaction with installed models.
• Privacy and Data Control: Since the tool runs locally, your data is not sent to external servers, ensuring enhanced security and privacy.
