AI coding tools can really make the "in the next week, I’ll do a whole month’s work. and no one will know" feel especially tempting, particularly if you're deep in the execution phase of a project. Truth is that can end up like Brooks's law on steroids.

Instead, just communicate with your stakeholders asap. Chances are they already know the project is at risk, and they'll be amendable to either descoping or pushing back the deadline.
