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

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.

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.

HuggingFaceFW/fineweb filter Malaysian context
What is it?
We filter the original 🍷 FineWeb dataset that consists more than 15T tokens on simple Malaysian keywords.
Total tokens for the filtered dataset is 174102784199 tokens, 174B tokens.
How we do it?
We filter rows using {'malay', 'malaysia', 'melayu', 'bursa', 'ringgit'} keywords on r5.16xlarge EC2 instance for 7 days.
We calculate total tokens using tiktoken.encoding_for_model("gpt2") on c7a.24xlarge EC2… See the full description on the dataset page: https://huggingface.co/datasets/mesolitica/fineweb-filter-malaysian-context.word_in_contextDataset homepage:

Dataset Summary
This dataset was crafted to be used in our tutorial [Link to the tutorial when ready]. It consists on a large Movie Review Dataset mixed with some reviews from a Hotel Review Dataset. The training/validation set are purely obtained from the Movie Review Dataset while the production set is mixed. Some other features have been added (age, gender, context) as well as a made up timestamp… See the full description on the dataset page: https://huggingface.co/datasets/arize-ai/movie_reviews_with_context_drift.context-conditioned-molecule-transfer-v10.4.1-bbb-martins-mixed-continuous-intern
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.

Dataset Summary
Long-context / document-level dataset for Quality Estimation of Machine Translation.
It is an augmented variant of the sentence-level WMT DA Human Evaluation dataset.
In addition to individual sentences, it contains augmentations of 2, 4, 8, 16, and 32 sentences, among each language pair lp and domain.
The raw column represents a weighted average of scores of augmented sentences using character lengths of src and mt as weights.
The code used to apply the augmentation… See the full description on the dataset page: https://huggingface.co/datasets/ymoslem/wmt-da-human-evaluation-long-context.named_entity_recognition_document_contextvla0-context-datasetThis dataset was created using LeRobot.

Memory Representation ContextBench Artifacts
Dataset Summary
This repository contains processed artifacts for the paper "Memory as a Map: Prior-Trajectory Representations for Software Engineering Agents." The artifact supports reproduction and inspection of a controlled prior-context representation experiment over SWEContextBench prior-target pairs.
The experiment renders each target under four prompt conditions: no prior context, stripped Claude Code transcript… See the full description on the dataset page: https://huggingface.co/datasets/shshwtsuthar/memory-representation-contextbench-artifacts.pretrain-encyclopedic-mix-long-contextNormalized documents plus aligned Dolma-2 tokens and target masks.

ContextProgress-Bench
ContextProgress-Bench is the benchmark of
ProgressCompass: Embodied Progress Reward Models Are Lost Without the Right Context.
It tests context-dependent progress estimation: robot-manipulation episodes in which the current
frame alone cannot tell how far the task has come, because progress depends on what happened earlier.
