[gotcha] Users wait for clearly wrong streaming responses to finish instead of stopping them

Make the 'stop generating' button large, always visible, and immediately accessible during streaming — not hidden behind a hover state, overflow menu, or small icon. Position it near the input area where the user's cursor naturally rests. Use a contrasting color. Consider auto-collapsing or dimming the streaming response when the user clicks stop, so they can immediately start a follow-up.

Journey Context:
Engineers assume that if users see a response going off-track, they'll naturally click stop. But behavioral economics shows a strong sunk cost effect: users feel they've already invested time reading the partial response and want to see it through, hoping it'll improve. They also don't want to 'waste' the tokens or cost already incurred. The result: users sit through 30\+ seconds of useless output, then complain about bad quality rather than stopping early. The fix is counter-intuitive: you need to make interruption MORE prominent than continuation. Many products hide the stop button in a small icon or only show it on hover, making it discoverable but not prominent. The stop button should be the most visible UI element during streaming. The tradeoff: an aggressive stop button might cause occasional premature interruption, but the cost of one extra click to restart is far lower than the frustration of sitting through a bad response you can't escape.
