by In a groundbreaking performance, a collaboration team of AI researchers from Stanford University and the University of Washington has successfully developed a new open-source “reasoning” model called S1. It is remarkable that this AI model was trained using less than $ 50 to cloud computing credits. The development of S1 offers an alternative to expensive AI models such as OpenAi’s O1, which brings the potential for powerful reasoning models to a wider audience.
The rise of S1: a cost-effective alternative to the O1 model of OpenAI
The S1 model has shown that it is able to perform at a level comparable to established reasoning models such as OpenAi’s O1 and Deepseek’s R1. The possibilities were tested in important assessments aimed at tasks such as mathematics and coding, where it delivered promising results. This open-source model is available on Github, where the corresponding training code and data set are also published, so that everyone has access and can experiment with it.
One of the most exciting aspects of the development of the S1 model is the cheap approach. Researchers used less than $ 50 in cloud computing credits to make the model, a cost-effective solution for developing robust AI systems. This contrasts sharply with the investments of several millions of dollars that are usually needed for top research and development of the top class.
How S1 was made: the distillation process
The research team started the development of S1 with the help of a ready-made basic model and refined it by a process mentioned distillation. Distillation is the technique to extract reasoning options from an existing AI model by training a new model on its output. In this case, S1 was distilled from one of Google’s reasoning models, the Gemini 2.0 Flash Thinking Experimental.
By applying distillation, the researchers were able to make a model that demonstrated strong reasoning options with a relatively modest data set. Distillation is generally cheaper than other techniques, such as learning reinforcement, which is used by many other AI developers such as Deepseek for making models similar to OpenAI’s O1.
S1’s strong performance and possibilities
The S1 model was trained with the help of a small data set consisting of only 1,000 compound questions and answers, including the reasoning behind each answer from Google’s Gemini 2.0. Despite this small data set, the performance of the model at AI benchmarks were impressive. In fact, after only 30 minutes of training on 16 NVIDIA H100 GPUs, it achieved these results for an amount of around $ 20. This reinforces the idea that strong performance in AI does not necessarily require enormous amounts of data or expensive sources.
Researchers also added a smart component to improve the reasoning options of the model. By including the term “waiting” in the process of S1, the model could pause during his thinking, so that it can be more time to achieve something more precise answers. This tactic significantly improved the accuracy of his answers, as set out in the research paper.
Implications in the industry: the commoditization of AI models
The success of the S1 model raises questions about the commoditization of AI models. Because researchers are able to replicate well-performing models with relatively small investments, there are concerns about the future of large-scale AI development and the competitive landscape for large AI laboratories. If a small research team can achieve such results with minimal resources, what implications does this have for the future of AI research and development?
There is a growing interest in the smaller entities or individual researchers can contribute to the field without having access to large budgets or business support. The emergence of cost-effective AI models such as S1 can lead to more democratic access to powerful reasoning models, making innovation all over the world possible.

Potential concerns: reverse engineering and ethical questions
Despite the success of S1, its development has expressed concern within the industry. For example, Google’s policy prohibits the reverse engineering of its models for creating competitive services, as was done with S1. This asks ethical and legal questions, in particular with regard to intellectual property rights and the future of AI model accessibility.
AI developers such as OpenAi and Deepseek have expressed concern about the distillation of their models and claim that competitors may benefit from their own data. With the rise of more accessible distillation methods, it is expected that these debates will continue to evolve.
What is the next step for AI development?
The success of S1 emphasizes the potential for creating well-performing AI models with minimal financial investments. However, it is important to note that distillation techniques, although effectively, do not necessarily lead to groundbreaking new models. As researchers focus on distillation methods to replicate existing possibilities, it will be important to continue to push the limits of innovation to create really new AI models that can perform even better than current ones.
Meta, Google and Microsoft are among the companies that invest billions of dollars in AI infrastructure and AI models of the next generation. Although distillation has proven to be a cost -effective strategy, large -scale investments will still be crucial for promoting the boundaries of AI, in particular in the field of model scalability and creating entirely new forms of reasoning.
The future of AI in 2025 and afterwards
In 2025 we can expect that we can see continuous progress in AI development, in particular because the industry is working on creating more efficient and accessible models. The success of S1 offers an exciting look at how AI can be democratized, with cheaper solutions that can contribute to the field with cheaper solutions with which more researchers and developers can contribute to the field.
As AI technology evolves, the challenges of balancing accessibility, intellectual property and innovation will continue to form the industry. But one thing is clear: AI becomes more powerful and the potential to bring about a revolution in several industries is growing day by day.
