[gotcha] Streaming creates a false mental model that the AI is reasoning in real-time, leading to misguided interruption patterns

Separate the 'thinking' phase from the 'response' phase in your UI. Show a distinct 'Analyzing your request...' state before streaming begins. When a user interrupts mid-stream, clearly indicate that a NEW generation is starting—not continuing the previous one. Add a brief stop animation that makes it obvious the previous response was discarded. Never let the UI imply the AI is 'typing its thoughts' in real-time.

Journey Context:
The gotcha: when users see tokens appearing one by one, they naturally assume the AI is 'thinking out loud'—reasoning in real-time like a human typing. But the model's output trajectory is largely determined during the pre-fill phase; the tokens are decoded sequentially but the overall direction is set. Mid-stream interruption does not 'redirect' the AI's thinking; it starts an entirely new generation. This false mental model causes users to interrupt mid-stream expecting a course correction, then get confused when the new response does not acknowledge their interruption context or takes a completely different direction. The fix: make the UI clearly distinguish between 'the AI is processing your request' and 'the AI is presenting its response,' so users understand that interrupting starts over, not redirects. Anthropic's extended thinking feature explicitly addresses this by surfacing the reasoning phase separately.
