Open WebUI

Open WebUI is a feature-rich web interface for interacting with large language models (LLMs), designed as a self-hosted alternative to ChatGPT. It connects to Ollama as the backend and provides a familiar chat interface with session management, model switching, and conversation history.

Key Features

• Chat interface: Clean, ChatGPT-like UI with markdown rendering and code highlighting.
• Model switching: Switch between different Ollama models (llama3.2, mistral, etc.) on the fly.
• Conversation history: Persistent chat sessions with search and export capabilities.
• Native OIDC: Built-in OIDC support for Keycloak single sign-on integration.
• Document upload: Upload text files for the LLM to analyze and reference in responses.

Integration with openDesk Edu

Open WebUI is part of the Collab Services suite and deploys via its upstream Helm chart (helm.openwebui.com). It authenticates through Keycloak using native OIDC support and is accessible at ai.* under the institution's wildcard DNS. It depends on Ollama as the LLM backend, which must be deployed first.
