How it works

Choice of Plausible Alternatives (COPA) is a benchmark dataset used to evaluate commonsense reasoning in language models. It presents a premise and asks the model to choose the more likely cause or effect from two alternatives. This task effectively measures an LLM's understanding of cause-and-effect relationships and general world knowledge.
