dyck-k128-seq_len_2048-1B
Procedurally generated k-shuffle Dyck bracket sequences (Hu et al. 2025, arXiv:2502.19249), as flat uint16 token-id .bin files. Token ids are 0-based: opening bracket type i is id i and its matching close is i + k, so ids span [0, 2k) and the vocabulary is 2k = 256.

Synthetic generations from

Each prompt is sampled n=16 times, and for every generated token the dataset
stores the chosen-token log probability plus the top-16 log probabilities

reranking, and uncertainty analysis.

BirdCode on DeepSWE — k=1, single attempt, no web tools
⚠️ Reading the metric correctly: The summary card's "Average f2p 0.89" is the
test-case-level pass fraction (f2p_passed/f2p_total, averaged per task) — it is
NOT the official DeepSWE leaderboard metric. The official binary score is the
reward field (1 only when all F2P and P2P tests pass): 60/113 = 0.531.

US K-12 Schools Directory
A directory of 124,613 US K-12 schools covering all 50 states, DC, and US territories,
compiled from federal and state government sources. Each record carries directory
information (address, phone, website), enrollment and demographics, and, where a source
supplied it, a principal name and email.
This is a compilation of public government data. It is not a survey, and no field was
independently verified against the school itself.
