Stanford and the University of Washington researchers trained an AI "reasoning" model for under $50 (around ₹4,400) in less than 30 minutes, TechCrunch reported. Researchers said the model, named s1, exceeded OpenAI's "o1-preview on competition math questions by up to 27%". Researchers used distillation, a method used to train smaller models by using outputs from larger ones, to refine s1.
