Choosing the AI model: Fast and Smart

What Fast and Smart mean, and what they cost in credits.

Fast and Smart

Open your chatbot, then Instructions & Model, then AI model.

  • Fast is the default. The question decides: easy questions use a quick, inexpensive model and harder ones use a stronger one.
  • Smart uses the stronger model for every question. It is better at long or tricky questions.

A Smart answer uses 3 credits for every 1 credit a Fast answer uses. One credit is 1,000 tokens. Reading your knowledge to find the right pages is not counted as an answer.
