Why three layers?

Most AI apps quietly hand your question to a lite model and pad the answer. Berges AI runs a frontier open-weights reasoning model on every turn, and two more layers sit on top: a pipeline you pick (Reasoning, WebSearch, Brainstorm or Empathy) that shapes how the answer comes out, and a chatbot you pick that sets the tone: Luis is concise, Sara is friendly, Peter is technical. Under all three, house rules keep it direct: answer first, no filler, prose first, today's date on hand, pasted links read in full.
