Google DeepMind announced a collaboration with Commonwealth Fusion Systems (CFS) to apply AI to plasma modeling and control—key challenges in building commercially viable fusion reactors. The partnership will combine DeepMind’s simulation and optimization methods with CFS’s tokamak engineering to stabilize plasma, test configurations, and iterate designs faster. If successful, AI-assisted modeling could compress timelines for prototype validation and grid-scale clean energy. Milestones will hinge on model fidelity, experimental validation, and hardware feedback loops.
