The AI takes on OpenAI's o1 reasoning variant. The model, dubbed s1, was trained using a dataset of 1,000 questions for under $50.

It's cheap to copy already built models from their outputs, but likely still expensive to train new models that push the boundaries.

A team of researchers at Stanford and the University of Washington have developed an AI reasoning model, s1, for less than $50. This is a massive achievement, given the notion that significant financial resources are essential for developing AI reasoning models.
