How j040-99/tugaai works
Open WebUI is a self-hosted AI platform for chatting with local or compatible cloud models, extended by retrieval, tools, and collaborative workspaces. The central workflow runs from a user message through the chat interface and API to model selection and a provider response; optional retrieval and tools add context or actions. The README documents substantial capabilities beyond the sampled source, so those appear as product branches without asserting unsampled internal call wiring. Paths identify exact files or directories in the supplied tree.
