What happens when you cancel
- The AI receives the stop signal and winds the session down — you’ll briefly see a “stopping” state while it does.
- The chat confirms: “Generation cancelled — you were only charged for the work completed before you stopped.”
- Your game keeps whatever the AI finished before the stop. Partial work (files written, assets generated) stays in the project; you can build on it, prompt over it, or revert to the previous version.
What you’re charged
Exactly the AI work done up to the cancel — metered from the AI’s actual usage at the normal rates, same as any other outcome. Cancelling early in a build costs little; cancelling at the 95% mark costs about as much as letting it finish. There is no cancellation fee and no full-run charge. See Failed & cancelled generations for the policy in detail.When cancelling makes sense
- Wrong direction, caught early — the progress feed shows the AI heading somewhere you don’t want. Stop, refine the prompt, go again.
- You forgot something important — stop, add it to the prompt, resend. (For additional thoughts, consider just queueing the follow-up instead — the current build finishes and the queue handles the rest.)
