A new entrant called S1 is once again reinforcing this idea, as researchers at Stanford and the University of Washington trained the “reasoning” model using less than $50 in cloud compute credits.

A new framework called AlphaOne is a novel way to modulate LLM thinking, improving model accuracy and efficiency without costly retraining.

The model, known as s1, performs similarly to cutting-edge reasoning models, such as OpenAI’s o1 and DeepSeek’s R1, on tests measuring math and coding abilities. The s1 model is available on ...
