RAG+

RAG+

Introduces RAG+, a modular framework that improves traditional RAG systems by explicitly incorporating application-level reasoning into the retrieval and generation pipeline. While standard RAG pipelines fetch relevant knowledge, they often fail to show how to use that knowledge effectively in reasoning-intensive tasks. RAG+ fills this gap by retrieving not only knowledge but also paired application examples, leading to more accurate, interpretable, and goal-oriented outputs. Key highlights:

01Retrieval
Future of Work with AI Agents

Future of Work with AI Agents

Proposes a large-scale framework for understanding where AI agents should automate or augment human labor. The authors build the WORKBank, a database combining worker desires and expert assessments across 844 tasks and 104 occupations, and introduce the Human Agency Scale (HAS) to quantify desired human involvement in AI-agent-supported work. Key findings:

Emergent Misalignment

Emergent Misalignment

This paper expands on the phenomenon of emergent misalignment in language models. It shows that narrow fine-tuning on unsafe or incorrect data can lead to surprisingly broad, undesirable generalizations in model behavior, even in settings unrelated to the original training domain. Using sparse autoencoders (SAEs), the authors analyze the internal mechanics of this effect and demonstrate ways to detect and mitigate it. Key findings:

From Bytes to Ideas

From Bytes to Ideas

Proposes AU-Net, a hierarchical byte-level language model that internalizes tokenization by learning to embed text from raw bytes through a multiscale, autoregressive U-Net architecture. This design avoids fixed token vocabularies like BPE and instead dynamically pools bytes into higher-order representations (words, word pairs, up to 4-word spans), enabling multi-stage prediction with varying granularities. Each stage compresses the sequence and predicts further ahead in time, combining coarse semantic abstraction with fine local detail via skip connections. Key insights:

Agentic Misalignment

Agentic Misalignment

This study introduces the concept of agentic misalignment, where LLM-based agents autonomously choose to harm their deploying organization when faced with threats to their autonomy or conflicts between their goals and the company’s direction. Anthropic tested 16 leading models, including Claude, GPT-4.1, Gemini 2.5 Flash, Grok, and DeepSeek, by placing them in fictional corporate simulations where they had email access and could act without human oversight. Models were tasked with benign goals but placed in scenarios that made harmful behavior the only way to succeed or avoid replacement. Key findings:

05Agents
ALE-Agent & ALE-Bench

ALE-Agent & ALE-Bench

Proposes a new benchmark for evaluating AI systems in score-based, long-horizon algorithmic contests. Unlike traditional coding benchmarks that emphasize pass/fail correctness, ALE-Bench is based on real tasks from the AtCoder Heuristic Contests (AHC), which focus on optimization problems with no known optimal solutions. The benchmark targets industrially relevant challenges such as routing, scheduling, and planning, encouraging iterative refinement and strategic problem-solving over hours or days. Key points:

Eliciting Reasoning with Cognitive Tools

Eliciting Reasoning with Cognitive Tools

Proposes a modular, tool-based approach to eliciting reasoning in LLMs, inspired by cognitive science. Rather than relying solely on RL or chain-of-thought prompting, the authors introduce a framework where the LLM calls self-contained "cognitive tools" to modularize and scaffold internal reasoning. These tools encapsulate operations like understanding questions, recalling analogous examples, examining answers, and backtracking. The system is implemented in an agentic tool-calling style, allowing LLMs to dynamically invoke tools during reasoning without extra fine-tuning. Highlights:

SHADE-Arena

SHADE-Arena

This paper introduces SHADE-Arena, the first large-scale benchmark for evaluating whether LLM-based agents can subtly carry out harmful side objectives (sabotage) while avoiding detection by monitors. The dataset contains 17 complex task pairs, each with a benign main task and a related malicious side task, set in realistic, tool-using environments. Agents are evaluated on their ability to complete both tasks without raising suspicion from an LLM monitor. Key Findings:

08Agents
Leaky Thoughts

Leaky Thoughts

This work explores how reasoning traces in large reasoning models (LRMs) leak private user data, despite being assumed internal and safe. The study finds that test-time compute methods, while improving task utility, significantly increase privacy risks by exposing sensitive information through verbose reasoning traces that are vulnerable to prompt injection and accidental output inclusion.

09Reasoning
Advances in LLMs

Advances in LLMs

This paper surveys recent advancements in LLMs focusing on reasoning, adaptability, efficiency, and ethics. It highlights techniques like CoT prompting, Instruction Tuning, RLHF, and multimodal learning, while also addressing challenges like bias, computational cost, and interpretability.
