Barbet long-context SFT
Release a9fe3ba5b4c2869855e4e75118262797572d695c146eaa8fed7a180ec3544381 preserves 6633 active records. This is one joint
assistant-only SFT dataset; no Barbet model training has been run.
The skill-prefill migration has revised 1245
of 1254 records from its fixed base snapshot.
Revisions replace their original records in the explicit shard lists above. Old

Overview
This dataset builds from WikiSQL and Spider.
There are 78,577 examples of natural language queries, SQL CREATE TABLE statements, and SQL Query answering the question using the CREATE statement as context. This dataset was built with text-to-sql LLMs in mind, intending to prevent hallucination of column and table names often seen when trained on text-to-sql datasets. The CREATE TABLE statement can often be copy and pasted from different DBMS and provides table names, column… See the full description on the dataset page: https://huggingface.co/datasets/b-mc2/sql-create-context.context_qa_sum_qwen3_synthetic
Context-based QA and Summarization Synthetic Dataset
Overview
This dataset contains synthetic context-based question-answering (QA) and summarization data. The data was synthesized using:
Source context: openbmb/Ultra-FineWeb
Synthesis model: Qwen3-30B-A3B-Instruct-2507
Each context is obtained by taking the initial segment of raw pretraining text from Ultra-FineWeb, truncated to at most the corresponding number of tokens, while ensuring the truncation does not occur in… See the full description on the dataset page: https://huggingface.co/datasets/yuyijiong/context_qa_sum_qwen3_synthetic.paracrawl_context
Dataset Card for ParaCrawl_Context
This is a dataset for document-level machine translation introduced in the ACL 2024 paper Document-Level Machine Translation with Large-Scale Public Parallel Data. It is a dataset consisting of parallel sentence pairs from the ParaCrawl dataset along with corresponding preceding context extracted from the webpages the sentences were crawled from.

ContextASR-Bench: A Massive Contextual Speech Recognition Benchmark
Automatic Speech Recognition (ASR) has been extensively investigated, yet prior benchmarks have largely focused on assessing the acoustic robustness of ASR models, leaving evaluations of their linguistic capabilities relatively underexplored. This largely stems from the limited parameter sizes and training corpora of conventional ASR models, leaving them with insufficient world knowledge, which is crucial for… See the full description on the dataset page: https://huggingface.co/datasets/MrSupW/ContextASR-Bench.ContextBench

LEDGER — Long-Context KPI Question Answering & Page Retrieval
This dataset is part of the LEDGER (Long-context Evaluation of Documents for
Grounded Extraction and Retrieval) benchmark.
It supports two of the three LEDGER tasks:
Page-level KPI retrieval — given a natural-language question about a financial
KPI and the corresponding annual report, retrieve the relevant page(s). Each row
includes TREC-style graded relevance judgments (qrels) over all candidate pages.… See the full description on the dataset page: https://huggingface.co/datasets/artefactory/ledger-long-context-KPI-QA.pretrain-commits-v2-mix-long-contextNormalized documents plus aligned Dolma-2 tokens and target masks.

Dataset Card for Ambient Acoustic Context
The Ambient Acoustic Context dataset contains 1-second segments for activities that occur in a workplace setting. Each segment is associated with speaker_id.
Dataset Details
Using Amazin Mechanical Turk, crowd workers were asked to listen to 1-second segments and choose the right label. To ensure the quality of the annotations, audio segments that did not reach majority agreement among the turkers were excluded.

Does Reinforcement Learning Truly Extend Reasoning?
This work explores the discrepancy in views on RL's effectiveness in extending language models' reasoning abilities. Some characterize RL as a capability refiner, while others see it as inducing new compositional skills.

BBB_Martins context-conditioned molecule transfer V10.4.1
This release preserves its direct panels and appends training-only, post-aggregate continuous assay-evidence transfer pairs. Query values remain hidden from prompts.
Train rows: 214,362
Validation rows: 30,299
Test rows: 29,919
V10.4.1 uses only continuous non-L5 assay evidence and applies the shared center-0.6, temperature-0.1 sigmoid with half-slope probability tails.
