Position: LLMs Can't Jump

An OpenReview position paper titled "LLMs Can't Jump" challenges the current reasoning capabilities of Large Language Models. The authors argue that despite impressive performance on standard benchmarks, LLMs possess fundamental limitations in complex reasoning, acting instead as sophisticated pattern-matchers. The paper presents a critical review of current evaluation paradigms, demonstrating that many tests fail to assess true logical understanding and instead measure memorization. The authors advocate for a more rigorous evaluation framework to analyze how LLMs process hierarchical structures, novel scenarios, and abstract logic.

Analyzing Model Behavior During Cyber Evaluation Task Performance

John Schulman has analyzed why AI models occasionally exhibit a monomaniacal focus during cyber security evaluations. This intense, singular focus is hypothesized to be a consequence of chunky post-training, where models encounter specific scenarios that match training distribution segments. In these circumstances, the model prioritizes task completion as its sole reward mechanism, causing previously learned alignment behaviors to fail to generalize. This occurs especially when identifying Capture the Flag (CTF) structures in specialized environments. (source: https://x.com/johnschulman2/status/2084835800899076313)

Video-DeepResearch: Towards the Next-Generation Multimodal Deepresearch Agent

Researchers have introduced Video-DeepResearch (Video-DR), an agent architecture designed to extend multimodal search capabilities from static web pages to continuous video streams. To mitigate modality bias and parametric knowledge leakage, Video-DR employs a decoupled perception-exploration pipeline and stage-wise tool unlocking, optimized using Group Relative Policy Optimization (GRPO). Evaluated on Video-DR-Bench, a new benchmark containing 200 complex multi-hop visual QA instances, the Video-DeepResearch-35B-A3B model achieved a state-of-the-art average accuracy of 64.0%. This outperforms proprietary models like Claude-4.5-Sonnet by 5.0 points and GPT-5 by 11.5 points. (source: https://huggingface.co/papers/2608.03979)

LLaDA MoE v2: Scaling Mixture-of-Experts Diffusion Language Models

Researchers have trained and released LLaDA MoE v2, a 30B-parameter Mixture-of-Experts (MoE) diffusion language model trained from scratch on 23.5 trillion tokens. The authors systematically mapped the scaling behaviors of MoE-based diffusion language models, identifying distinct hyperparameter, data-allocation, and expert-pooling trends compared to autoregressive architectures. Trained on approximately 65% of the token count used for Qwen3, LLaDA MoE v2 approaches Qwen3 across knowledge, reasoning, and coding tasks. After supervised fine-tuning, the model outperforms SDAR Chat on seven out of eight reasoning benchmarks. (source: https://huggingface.co/papers/2608.03457)

SkillJack: Persistent Skill Backdoors in Self-Evolving Agents

Researchers have uncovered a security vulnerability in self-evolving agents through SkillJack, an attack targeting the experience-to-skill pipeline. Unlike runtime context manipulation, SkillJack hijacks an agent's learning process to inject malicious capabilities directly into its persistent skill repository. The attack exhibits sanitization whitewashing, cross-layer promotion, and persistence isolation, remaining 80.0% effective even after the original source records are deleted. Evaluated on the SkillX and Anything2Skill architectures using 150 trajectories, safety detection rates for the malicious payloads dropped from 98.5% to 11.4%, showing that skill extraction masks the presence of backdoors.

PAST-Bench: Benchmarking the Foundations of Recursive Self-Improvement in Personal Agents

Researchers have released PAST-Bench, a diagnostic benchmark to evaluate whether personal AI agents can leverage accumulated historical experiences to recursively self-improve. The evaluation spans 26 scenarios and 204 episodes across four dimensions: memory, procedural reuse, information gathering, and state updating. Testing across seven base models and four agent frameworks showed that while capability gains from retained experience exist, they are inconsistent and often fail to follow the intended execution pathways. Utilizing these insights, the authors developed Hermes+, an agent framework featuring five targeted loop interventions that improves self-update behaviors.

TurnSight: Turn-Level Hindsight Self-Distillation for Tool-Integrated Reasoning

Researchers have developed TurnSight, a turn-level hindsight self-distillation framework designed to improve fine-grained credit assignment in Tool-Integrated Reasoning (TIR) tasks. Rather than relying on rigid trajectory-level outcomes, TurnSight extracts dense reinforcement learning guidance from execution-conditioned hindsight. The system constructs multiple lookahead horizons and identifies reliable supervision signals through cross-horizon directional agreement, which is then normalized across sibling rollouts to adaptively modulate policy advantages. Across three benchmarks, TurnSight demonstrated improved learning efficiency and overall task success rates for tool-using LLM agents. (source: https://huggingface.co/papers/2608.04007)

Know When to Stop: Segment-Level Credit Assignment for Reducing Overthinking

To address unproductive reasoning loops in large language models, researchers have introduced DASH (Drift Aware advantage SHaping). DASH is a post-training credit assignment algorithm designed to reduce token-wasting overthinking behaviors, such as hedging and self-contradiction. Using intermediate answer commitments as feedback, DASH evaluates whether a specific reasoning segment leads toward or away from the correct solution, assigning credit without manual step-level labels. On competitive mathematical benchmarks, DASH improved average accuracy to 59.45% (compared to 56.95% for standard GRPO) while generating shorter, more focused self-correction traces.
