The S1 model has been compared to OpenAI’s o1 and DeepSeek’s R1 reasoning models. According to the researchers, s1 outperforms o1-preview by up to 27% on mathematical reasoning tasks.

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 ...
