Microsoft researchers released Delulu, a benchmark dataset containing 1,951 code generation samples across 7 programming languages designed to test how well large language models detect hallucinations in Fill-in-the-Middle tasks. Testing 11 open-weight models revealed fundamental limitations, with even the strongest achieving only 84.5% accuracy, indicating that code hallucination remains a persistent challenge across all model families.

The breakthrough uses a Periodic Geometric Decay schedule to overcome limitations in existing attack methods, exposing a critical vulnerability in DNN-based compression systems that previous techniques could not achieve.
Researchers introduced ComplexMCP, a benchmark for evaluating large language model agents in realistic, complex environments with interdependent tools and environmental noise. Testing revealed that current LLMs achieve only 60% success rates compared to 90% human performance, identifying three critical failure modes: tool retrieval saturation, over-confidence, and strategic defeatism.
Researchers introduce MATRA, a threat modeling framework designed to systematically assess security risks in autonomous AI agent systems. The framework combines asset-based impact analysis with attack trees to quantify how LLM vulnerabilities translate into real-world deployment risks, demonstrating its effectiveness on an OpenClaw personal agent case study.

NanoResearch introduces a multi-agent LLM framework that personalizes research automation through three co-evolving components: a skill bank for reusable procedural knowledge, a memory module for user-specific experience, and label-free policy learning for preference internalization. The system addresses the gap between uniform AI outputs and diverse researcher needs, demonstrating substantial improvements over existing AI research systems while reducing costs across successive cycles.
Researchers demonstrate that sparse autoencoders (SAEs) used to interpret AI model activations face fundamental geometric constraints rather than just resource limitations.

The system achieves up to 2.28× speedup on large models like Qwen3-235B while maintaining minimal interference to smaller models' native workloads.
A new threat called Agentic Denominator Gaming could exploit AI conferences' stable acceptance rates by flooding submissions with low-quality papers generated by automated agents, inflating the denominator to boost legitimate papers' acceptance odds without intending publication of the spam itself. This systemic vulnerability exposes academic peer review to coordinated attacks that would degrade review quality and increase reviewer burnout while requiring institutional policy reforms beyond technical solutions.
Researchers introduce M2A, a novel model merging paradigm that combines mathematical and agentic reasoning in large language models without retraining.
