Hierarchical Reasoning Model: The AI Architecture Outperforming OpenAI’s ‘o3-mini-high’ Key breakthrough: Singapore-based Sapient Intelligence lab has developed a 27-million parameter model that solves complex reasoning tasks with just 1,000 training samples – outperforming leading LLMs like DeepSeek-R1 and Claude 3. Why Current AI Models Struggle with Reasoning Today’s top language models (LLMs) face fundamental limitations in logical reasoning: 1. Architectural Constraints Fixed-depth architectures can’t scale with problem complexity Non-Turing complete design limits computational capability Polynomial-time problems remain unsolvable (research evidence) 2. Fragile Reasoning Process Over-reliance on Chain-of-Thought (CoT) prompting Single misstep causes complete reasoning derailment (2402.08939) Human reasoning occurs in …
