Amid all the excitement about and increasing use of artificial intelligence, there’s growing concern about its darker side — its environmental impact.
Researchers have known for several years now that training large-scale AI models that power applications like ChatGPT requires lots of energy. GPT-3, the model OpenAI later refined for ChatGPT,, according to a 2021 research paper on which UC Berkeley computer science professor David Patterson was the lead author. That’s equivalent to the amount of electricity 123
However, with AI models that are intended for real-world use, training is just the first step. The second is inference, in which the models use their training to respond to novel queries and prompts, such as when a user asks ChatGPT to compose a term paper as if written by Shakespeare. But all those queries and prompts can add up quickly, and bigger models tend to require more energy for inference than smaller ones, according to the 2023 Luccioni paper. Indeed, thanks to the widespread use of ChatGPT, that model likely used more energy in responding to people’s prompts than was needed to train it within just a few months of its launch, according to the paper.
Google’s Standiford declined to say how much carbon dioxide was emitted as a result of training Gemini. The company uses “tested practices” to reduce data-center-related emissions, she said. . Scientists have long argued the world needs to stay below that limit to avert the worst effects of climate change.
The committee — dubbed Believe in SF, Lurie for Mayor 2024 — disclosed spending $216,000 on a February mailing and $279,000 on an April 15 mailing, neither of which included the window sign that was delivered this month. The naked display of financial resources has left other campaigns aghast. Money might not buy elections, but it sure buys a hell of a lot of campaign signs, online ads and political mailers.
Though San Francisco’s dislike for city government is well-documented, incumbency does come with advantages. Breed was able to place measures directly on the March primary ballot and successfully campaigned behind them, raising her status before the mayoral campaign began in full swing.
