Latest DL language models such as Groover ( https://arxiv.org/abs/1905.12616 ) costs up to 600k USD just for training the final model. At the same time, training a single AI model can emit as much carbon as five cars in their lifetimes ( https://www.technologyreview.com/s/613630/training-a-single-ai-model-can-emit-as-much-carbon-as-five-cars-in-their-lifetimes/ ).

Is this a sustainable trend especially for research labs in academia which lack funding?
