Which model you are talking to
The model menu at the top shows which model answers. Every model in GlirOS knows its own name and maker, roughly when its training ends, and what GlirOS adds: web search and reading links (unless web access is switched off in Settings > Web search), files in the side panel, the current time, continuing long answers and condensing long chats. Ask it "what model am I talking to?" and it explains. The GlirOS Helper is a small model on this device that knows GlirOS best; bigger models for the graphics card, cloud models with your own key and the desktop app give better answers for other work. When a chat gets stuck, GlirOS offers Condense and continue (the chat goes on from a summary, in the same chat) or another model.
This guide is the same text GlirOS itself uses to answer questions about GlirOS.
