TruthfulQA
Unknown817 questions across 38 categories, written to elicit imitative falsehoods - the misconceptions a model picks up from its training text rather than errors of reasoning. It ships generation and multiple-choice configurations and dates from 2021.
Relatively dated and largely saturated by frontier models, though still widely reported. Verified 2026-08-13 via the truthfulqa/truthful_qa dataset card on Hugging Face and the paper abstract.

Adoption
4 medium confidence109,020 Hugging Face downloads in the trailing 30 days for truthfulqa/truthful_qa, which puts it in the 100K-1M band, level 4 on the dataset adoption scale. That scale tops out at >1M, an order of magnitude below the ones used for software and models, because no dataset in this corpus has ever passed 10M downloads. TruthfulQA is a long-standing truthfulness benchmark, though an older one and increasingly saturated.
