How and Why LLMs Generalize: A Fine-Grained Analysis of LLM Reasoning from Cognitive Behaviors to Low-Level Patterns

By Haoyue Bai, Yiyou Sun, Wenjie Hu, Shi Qiu, Maggie Ziyu Huan, Peiyang Song, Robert Nowak, Dawn Song

85 score
AI Analysis
Introduces benchmark decomposing LLM reasoning into atomic core skills (calculation, fact retrieval, simulation, etc.) to analyze why SFT narrows capability while RL preserves it. Provides granular analysis of how cognitive abilities emerge and collapse during post-training.
Source details
Large Language Models (LLMs) display strikingly different generalization behaviors: supervised fine-tuning (SFT) often narrows capability, whereas reinforcement-learning (RL) tuning tends to preserve it. The reasons behind this divergence remain unclear, as prior studies have largely relied on coarse accuracy metrics. We address this gap by introducing a novel benchmark that decomposes reasoning into atomic core skills such as calculation, fact retrieval, simulation, enumeration, and diagnostic,

Can Small Training Runs Reliably Guide Data Curation? Rethinking Proxy-Model Practice

By Jiachen T. Wang, Tong Wu, Kaifeng Lyu, James Zou, Dawn Song, Ruoxi Jia, Prateek Mittal

82 score
AI Analysis
Reveals critical flaw in proxy model practice: using identical training configurations across data recipes for 'fair' comparison leads to conclusions that flip with minor hyperparameter changes, as optimal config is data-dependent.
Source details
Data teams at frontier AI companies routinely train small proxy models to make critical decisions about pretraining data recipes for full-scale training runs. However, the community has a limited understanding of whether and when conclusions drawn from small-scale experiments reliably transfer to full-scale model training. In this work, we uncover a subtle yet critical issue in the standard experimental protocol for data recipe assessment: the use of identical small-scale model training configur

What Drives Success in Physical Planning with Joint-Embedding Predictive World Models?

Investigates what makes JEPA-based world models work for physical planning, studying key components including representation learning, planning algorithms, and training choices. Provides comprehensive empirical analysis.
Source details
A long-standing challenge in AI is to develop agents capable of solving a wide range of physical tasks and generalizing to new, unseen tasks and environments. A popular recent approach involves training a world model from state-action trajectories and subsequently use it with a planning algorithm to solve new tasks. Planning is commonly performed in the input space, but a recent family of methods has introduced planning algorithms that optimize in the learned representation space of the world mo

Jailbreaking Attacks vs. Content Safety Filters: How Far Are We in the LLM Safety Arms Race?

By Yuan Xin, Dingfan Chen, Linyi Yang, Michael Backes, Xiao Zhang

82 score
AI Analysis
Presents first systematic evaluation of jailbreak attacks against the full LLM inference pipeline including input/output content moderation filters, not just the model alone. Reveals significant gaps between model-only and pipeline-level security assessments.
Source details
As large language models (LLMs) are increasingly deployed, ensuring their safe use is paramount. Jailbreaking, adversarial prompts that bypass model alignment to trigger harmful outputs, present significant risks, with existing studies reporting high success rates in evading common LLMs. However, previous evaluations have focused solely on the models, neglecting the full deployment pipeline, which typically incorporates additional safety mechanisms like content moderation filters.

Score-based sampling without diffusions: Guidance from a simple and modular scheme

By M. J. Wainwright

78 score
AI Analysis
M.J. Wainwright presents a modular score-based sampling framework that reduces sampling to solving a sequence of strongly log-concave problems, avoiding diffusion complexity. Enables use of any SLC sampler for backwards path.
Source details
Sampling based on score diffusions has led to striking empirical results, and has attracted considerable attention from various research communities. It depends on availability of (approximate) Stein score functions for various levels of additive noise. We describe and analyze a modular scheme that reduces score-based sampling to solving a short sequence of ``nice'' sampling problems, for which high-accuracy samplers are known. We show how to design forward trajectories such that both (a) the te

The first 100% autonomous coast-to-coast drive on Tesla FSD V14.2! 2 days 20 hours, 2732 miles, zero interventions. This one is special because the coast-to-coast drive was a major goal for the autopilot team from the start. A lot of hours were spent in marathon clip review sessions late into the night looking over interventions as we attempted legs of the drive over time - triaging, categorizing, planning out all the projects to close the gap and bring the number of interventions to zero.
