I feel like that info is placed appropriately. The abstract mentions that energy disparity persists across models, the rest follows the standard Intro -> Related Work -> Experiments structure

Edit: sorry, i went straight to the paper. I agree, the article itself (and the headline) are bad (as they tend to be on this topic)

How would one evaluate the energy consumption of models accessible only through Anthropic or OAI APIs? You can't fire them up on your own computers and measure power consumption.
