  3. 3The model generates conversational responses based on the input it receives from users.
  4. 4For voice interactions, it uses a pipeline of three separate models: one for transcribing audio to text, an LLM (GPT-3.5 or GPT-4o) for processing text and generating responses, and another for converting text back to audio.
