Ollama is the easiest way to get up and running with large language models such as gpt-oss, Gemma 3, DeepSeek-R1, Qwen3 and more.
Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform designed to operate entirely offline. It is built around universal standards, supporting Ollama and OpenAI-compatible Protocols (specifically Chat Completions). This protocol-first approach makes it a powerful, provider-agnostic AI deployment solution for both local and cloud-based models.
