Researchers slash AI power draw one hundredfold with a new inference method.
A team replaced standard matrix multiplications with a sparse, event-driven algorithm that activates only 1 percent of weights per forward pass. On ImageNet they recorded a 100 times drop in joules per inference and a 0.8 percent rise in top-1 accuracy. The method runs on unmodified GPUs using a custom CUDA kernel released under an open-source license.
