A team of researchers created an AI model called s1 for less than $50. This model can think and reason like a human. It was trained using only $50 in cloud credits. The model is open-source, meaning anyone can use it for free. The s1 model performs as well as expensive AI models like OpenAI's o1. It was tested in math and coding tasks and did well. The model can be found on GitHub, along with its training code and data. The researchers used a technique called distillation to create s1. This involves training a new model based on the outputs of an existing model. They used Google's model to create s1. Even though s1 was trained on a small dataset, it performed impressively. The researchers added a component to help the model pause and think more accurately. This low-cost model challenges the high prices usually associated with AI research. It may change how AI is developed in the future. However, some companies are concerned about the ethics of using their models in this way. In 2025, we can expect more advancements in AI. The s1 model shows that powerful AI doesn't have to be expensive. Research will continue to push the boundaries of innovation to create even better models. AI is becoming more powerful and will revolutionize many industries.
