A company is developing a real-time, interactive chatbot for customer support. The primary goal for user experience is that once the chatbot starts replying, the rest of its message appears to stream smoothly and continuously, creating a fluid conversational flow. The team is evaluating two different language models:

• Model Alpha: Responds almost instantly after the user sends a message, but each subsequent word appears with a noticeable, consistent pause.
• Model Beta: Takes a moment longer to begin its response, but once it starts, the entire rest of the message is generated very rapidly with no perceptible delay between words.

Which model should the company choose to best achieve its primary user experience goal, and why?
