(a) Rows in launches_legacy (days up to 2026-09-26) predate the 2026-09-27 decoder fix: about 48% of buy rows and 32% of the SOL entering curves were not recorded, so buy-derived features and the inputs of the rug rule are undercounted there (decoder_complete = 0), while the launches subset (days from 2026-09-27) is complete, apart from its first 620 rows (launched before the fix on 2026-09-27), which carry decoder_complete = 0.

VERIFY: A Pipeline for Factuality Evaluation
Language models (LMs) are widely used by an increasing number of users, underscoring the challenge of maintaining factual accuracy across a broad range of topics. We present VERIFY (Verification and Evidence Retrieval for Factuality evaluation), a pipeline to evaluate LMs' factual accuracy in real-world user interactions.

e621-2024
e621-2024 is a large-scale furry image dataset retrieved from e621, a mature furry imageboard. This dataset is heavily inspired by the danbooru2023 dataset.
Similar to danbooru2023, the images in this dataset are bucketed into 1000 subdirectories (0000-0999), which is the E621 ID modulo 1000 (so all images in 0999/ have an ID ending in '999').
Currently there is no loading script for this dataset, so loading it with HuggingFace datasets is not supported.
