The most powerful AI models emit up to 50 times more carbon dioxide than smaller ones

The artificial intelligence (AI) boom has sharply increased energy consumption and carbon emissions of major tech companies, as AI systems must process massive amounts of data using high-powered machines. But not all generative AI models consume the same amount of energy. A group of researchers set out to determine which models are the most polluting and which are the most efficient. Their conclusion: smaller models (those trained with fewer parameters) can produce up to 50 times less pollution than larger ones — but their answers tend to be less accurate, and vice versa. The greater the precision, the greater the pollution.
