Nature commentary questions AI data center energy savings

Nature has published a commentary on a research article by Cassidy Buhler and colleagues arguing for researchers to move away from mega data centers and run open-weight AI models on local institutional servers.

• The piece references Buhler et al.’s article in Nature 656, 296–298 (2026) and says the case for greater autonomy over research tools is strong.
• It also cautions that the authors’ claims about energy savings are not yet well supported, describing the evidence as weak.
