WinoGrande

Reasoning

WinoGrande scales the Winograd Schema Challenge to 44,000 problems in which a pronoun must be resolved between two sentences that differ by one word. It was built through a procedure that strips dataset-side bias.

History

The Allen Institute for Artificial Intelligence introduced WinoGrande in 2019 to scale up commonsense language understanding evaluation inspired by the Winograd Schema Challenge. The project sought a large collection with fewer exploitable statistical cues than ordinary crowdsourced data. The March 2022 Hugging Face publication recorded here refers to a later distribution.

How it was built

WinoGrande was built from crowdsourced sentence-completion problems and subjected to adversarial filtering to reduce dataset biases. The source contains about 44,000 problems, each presenting a sentence with a blank and two candidate fillers. Evaluation protocols include different amounts of training data, ranging from 160 to 40,000 examples.

At a glance

What a problem looks like

A sentence with a blank and two candidate fillers.

How it is scored

The source ships the correct option; nothing is imported here.

Metric: accuracy, reported across training-set sizes from 160 to 40,000 examples

Reported scores

Evaluation conditions differ between rows, so this is not a ranking. Rows marked vendor are reports by the model’s own organization.

Why it is hard

The two sentences differ by a single word, so every cue except the intended commonsense one is held constant.

Limitations and criticism

Adversarial filtering reduces cues detectable by the filtering procedure; it does not establish that all statistical shortcuts have been removed. Binary sentence completion measures a constrained form of commonsense language understanding rather than open-ended reasoning about the world. Scores also depend on the amount of task-specific training data, so those protocols should be distinguished from few-shot prompting.

How much room is left

The recorded vendor report gives DeepSeek-V3 base 84.9 percent accuracy with five examples in the prompt. That result leaves headroom under the stated protocol, although the two-choice format has a 50 percent uniform-guessing baseline. A single few-shot report does not establish the best achievable result under the supervised training protocols.
