Only if you insist on an omniscient system. A large model memorizes everything — every movie, every style, every domain — because it cannot anticipate what you will ask next. It memorized all of Studio Ghibli because it did not know whether your next question would be "Make this a Ghibli film." But if you know your particular need, the vast majority of those parameters are unnecessary. A model that only translates between English and Tibetan may need one billion parameters out of a trillion. What required a large data center suddenly fits on a phone. This is how Apple builds its models: one small model for email summarization, another for translation, another for a specific function. All fit on the device. Very little energy is required.
