Artificial Intelligence Logic and Authenticity, penned by our author and Aravind Srinivas
In the world of artificial intelligence (AI), a new approach has emerged that is set to revolutionize the way AI systems think and reason. This approach, known as the Chain of Thought (CoT), encourages AI models to generate explicit, step-by-step explanations of their reasoning processes.
Amazon's recent research is a testament to the power of this approach. By using ensembles of AI agents to generate high-quality CoT annotated training data, they achieved an average 29% performance improvement on multiple reasoning benchmarks compared to baseline models[2].
Google's Gemini 2.5 Deep Think model takes this a step further. This model uses a multi-agent system that explores multiple reasoning paths in parallel before selecting the best answer. This approach earned the model a gold medal at the 2025 International Math Olympiad, reflecting a major improvement over previous AI reasoning approaches[1].
Researchers have also discovered that transformer-based language models develop internal, tree-like mathematical representations to track evolving information through their reasoning chains. Understanding and controlling these internal mechanisms have improved the reliability of dynamic reasoning tasks such as forecasting[3].
The transparency provided by chain of thought reasoning offers new opportunities for AI safety. By monitoring the explicit reasoning steps, researchers hope to detect and mitigate unintended or unsafe AI behaviors in real time, though this approach is still fragile and requires further research to scale to more capable systems[4].
An intriguing aspect of the CoT approach is the concept of bootstrapping intelligence. When models are trained on their own chain of thought rationales, it creates a cycle of improvement, potentially leading to even more advanced reasoning capabilities[5].
However, the cost of running such extensive computations could be millions, raising questions about access and control in AI research. The limiting factor in advanced AI reasoning is increasingly compute, not data or algorithms[6]. This could potentially exacerbate existing inequalities in access to AI research and development.
The future of AI may not be about replacing human curiosity, but rather amplifying and accelerating our natural desire to learn and discover. The development of AI systems that can exhibit genuine curiosity could lead to more innovative and unpredictable outcomes in AI reasoning[7].
In conclusion, recent work in AI reasoning demonstrates that chain of thought techniques, especially when combined with multi-agent deliberation and refined training data, lead to substantial and sometimes unexpected improvements in reasoning capabilities across diverse domains, from mathematical problem solving to policy adherence and safety monitoring[1][2][3][4][5][6][7]. As we continue to explore and refine this approach, the potential for AI to reason more like humans and to help us solve complex problems becomes increasingly exciting.

Big questions about access and control in AI research emerge as the cost of running chain of thought reasoning can amount to millions. This could potentially exacerbate existing inequalities in the field, as the limiting factor in advanced AI reasoning becomes computational resources rather than data or algorithms.
Technology such as the Chain of Thought (CoT) approach, if successful in reasoning more like humans, could amplify and accelerate our natural desire to learn and discover, leading to more innovative and unpredictable outcomes in AI reasoning.
