## Baby 4.0 (current flagship)

Baby 4.0 is Brainbaby's current flagship chat and reasoning engine, replacing Baby 3X as the default across chat, presentations, and the app builders. Its defining feature is **selectable reasoning depth**: each request runs at low, high, or max effort, so users trade latency against thoroughness rather than being locked to one setting. Deep Analysis mode maps to max effort. Baby 3X remains documented as the previous generation.
