What sets it apart from other AI models is its ‘test-time scaling,’ a technique that allows it to iterate its responses by dynamically using additional computational resources during testing. Reportedly,

Researchers at Stanford and the University of Washington have developed a model that performs comparably to OpenAI o1 and DeepSeek R1 models in math and coding — for less than $50 of cloud compute credits.

AI researchers at Stanford and the University of Washington were able to train an AI "reasoning" model for under $50 in cloud compute credits, according

However, Microsoft AI CEO Mustafa Suleyman revealed that all users of Copilot will be able to access OpenAI’s “world class o1 reasoning model”. While Copilot does have a paid Pro version, free users are also getting access to the new feature.

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.
