The jump from the predecessor is easy to feel in the details: fluid motion looks steadier, complex scenes render more convincingly, and the simulation layer is getting thicker, including more realistic people and added audio effects like crashing waves. Google also says Genie 4 is being studied for robotics training, where it can generate step-by-step prompts (via Gemini 4 Argon) to guide an experiment from description to executable tasks.
