Imagine a user interacting with a real-time AI chatbot. They type a prompt, and the model begins a heavy inference cycle. Suddenly, the user realizes they made a typo and rephrases the query. If your app continues to crunch the numbers for that first, now-irrelevant request, it’s wasting precious GPU cycles, draining the battery, and delaying the response the user actually wants.

This means a task isn't forced to stop; instead, it is politely informed that its work is no longer needed.…
