Extending English quality classifiers to data selection for multilingual LLM pretraining

The authors scored machine-translated text with English quality classifiers and used those scores to train a small MLP on top of multilingual embeddings. Without language-specific labeled data, this matched existing multilingual filtering methods across more than 100 languages.

Does generalist graph anomaly detection really need real training data?

The authors built AG-Forge, which automatically synthesizes anomalous graphs, and TS-GGAD, which trains on them at scale. A model trained without any real data achieved the best performance on all 14 real datasets.

Cited but not relied upon: a counterfactual audit of legal CoT faithfulness

The authors ran counterfactual experiments that keep the facts fixed and change only the legal provision cited as the basis for the verdict. The results show that even when an LLM cites the correct basis, its verdict often does not actually depend on that basis.

From Traces to Agent Worlds: Agentic Language World Models That Simulate Interactive Environments

By restructuring past interaction traces into an environment 'worldbook' and simulating the environment with a world model agent that consults it, the method produced more faithful and consistent simulations than existing prompt-based approaches.

Learn2Play Bench: How Well Do LLM Agents Learn from Experience in Unfamiliar Environments?

The authors built a benchmark of 20 text games whose rules are hidden or run counter to common sense, measuring LLM agents' ability to learn through interaction rather than from prior knowledge.

SuperNav: An Agentic Navigation System That Works for Any Task in Any Scene

By wrapping a pretrained MLLM, without fine-tuning, in a navigation-specific agent harness (Skills, Tools and context management), the system achieved higher success rates than the 4 baselines it was compared against across several navigation tasks.

Which Rollout Taught That Behavior? BehaviorTrace, Testing the Limits of Training Data Attribution in Online Reinforcement Learning

In controlled GRPO training experiments with a planted behavior of known origin, the authors show that much of the signal from gradient-based training data attribution comes from confounding factors.

Kuration SDK: Closing the Virtual2Real Gap with Data Curation

By comparing diffusion world models trained on CS:GO and CS2 gameplay, the authors showed that FVD and LPIPS do not reflect actual playing quality, and used a data diagnostic tool to narrow the cause down to differences in how much the screen changes in response to actions.

LeCuration: A Small World Model as a Multipurpose Tool for Data Curation

The authors trained a small JEPA-based world model with about 15 million parameters on CS:GO data in a few hours and showed qualitatively that its embeddings and prediction errors can serve as data curation signals for clustering, anomaly detection and similar tasks.
