It’s not just AI models. Just about everything everybody does today involves one or more cloud-based services. This means servers running in data centers, whether they’re running AI models or simple shell scripts or anything in between.
ChatGPT may consume a lot of power for the aggregate of its users, but so do the non-AI services that manage, for example, everybody’s smart lightswitches or doorbell cameras or video livestreams or on-line gaming, etc.
