Exact excerpt

Cognitive theory categorizes human thinking into two systems: the fast, intuitive System 1 and the slower, deliberate System 2. Large Language Models (LLMs) exhibit similar specialization. ... In contrast, the slower, more deliberate long thinking utilized by Large Reasoning Models (LRMs), such as DeepSeek-R1 and OpenAI’s o1 series, demonstrates superior performance on advanced tasks.
