The *SHROOM series is designed to stress-test core issues in hallucination evaluation, like black- v. white-box (SHROOM) or multilinguality (mu-SHROOM). For SHROOM-Visions, the hidden angle was benchmark obsolescence. Making the SHEEP dataset to answer that was a lot of work, but also a lot of fun 🐑
