About Ollama
Ollama is an open-source tool that enables users to run and manage large language models (LLMs) locally on their own hardware. It provides a simple command-line interface (CLI), a REST API, and client libraries for Python and JavaScript, allowing developers to integrate LLMs into applications, chat interfaces, and automated workflows. Ollama supports a wide range of models including Gemma 4, DeepSeek, Qwen, and more, and can utilize backends like llama.cpp. It also offers integrations with popular tools such as Claude Code, Copilot CLI, and OpenClaw, making it easy to embed local AI capabilities into existing development environments and communication platforms.
