Concept
Reasoning
A model's ability to chain logical steps, plan, or solve problems beyond pattern recall.
Definition
Reasoning capability is the multi-step problem-solving behaviour observed in large models, often amplified by chain-of-thought prompting or dedicated reasoning training (o1, R1, Claude thinking). Reasoning quality is measured on benchmarks like MMLU, GSM8K and ARC.
