Researchers in artificial intelligence (AI), from Stanford and the University of Washington, have trained a "cutting-edge" reasoning AI model for under $50 in cloud compute credits, according to a research paper published recently. The model, named s1, purportedly rivals industry-leading models like OpenAI's o1 and DeepSeek's R1 in tests of math and coding skills. The s1 model, along with the data and code used for training, is now available on GitHub. The team behind s1 started with an off-the-shelf base model and fine-tuned it through distillation, a process that extracts reasoning abilities from another AI model by training on its...
