New AI Reasoning Model Rivaling OpenAI Trained on Less Than $50 in Compute

It is becoming increasingly clear that AI language models are a commodity tool, as the sudden rise of open source offerings like DeepSeek show they can be hacked together without billions of dollars in venture capital funding. 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.

S1 is a direct…
