So called “accelerate-go” versus “accelerate-stop”. It is conditional, and not limited to these two models. They need to accelerate to a specific airspeed based on loading, temperature, and usable runway length. Prior to that airspeed, engine failure means abort. At and after reaching that speed, takeoff continues.
