For training yes, but during operation by this studies measure Deepseek actually has an even higher power draw, according to the article. Even models with more efficient programming use insane amounts of electricity

This was higher than all other tested models, except for OpenAI’s o3 (25.35 Wh) and Deepseek’s R1 (20.90 Wh).
