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

Researchers managed to create a low-cost AI reasoning model rivaling OpenAI’s in just 26 minutes, as outlined in a paper published last week. The model, called s1, was refined using a small dataset of 1,

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.
