Chain of Thought

← all concepts

Definition

Chain-of-thought prompting asks a model to think step-by-step before answering, dramatically improving performance on reasoning-heavy tasks. The trick works because the model is now using its own intermediate tokens as working memory, but the visible chain is not always the real chain.
