big-AGI
A feature-rich open-source AI suite with personas, multi-model chat, and side-by-side response comparison.
big-AGI is a power-user chat interface. Beyond ordinary chat it offers personas, multi-model "beam" comparison where several models answer at once, and tools for drawing and calling functions.
It is aimed at people who want to push models hard and compare them, rather than at a locked-down deployment for general staff.
Where it fits
A fit for technical users who want to experiment across models and compare answers in one interface.
Where it does not fit
Its breadth is a distraction for a simple, single-purpose internal assistant.
