Ollama is an open-source software platform developed by Jeffrey Morgan and Michael Chiang in 2023 for running and managing large language models on local GPU infrastructure and through hosted cloud models. It provides a command-line interface, a native GUI, a local REST API, model-management tools, and integrations for using open-weight models with coding assistants and other applications.
Ollama was first released in July 8, 2023. The project became associated with the growth of local large language model software, allowing users to download and run models such as Llama, Gemma, Mistral, Qwen, gpt-oss, GLM and DeepSeek on a local machine.
In 2025 and 2026, Ollama added additional application and cloud features, including hosted cloud models, web search support, tool and coding-agent integrations, and support for using Ollama with applications such as Claude Code, Codex, OpenCode, Copilot CLI, and OpenClaw. In March 2026, Ollama announced preview support for Apple silicon.
