Researchers introduce A.DOT Planner, an AI framework that enables multi-hop question answering across hybrid data lakes containing both structured and unstructured data.

Researchers argue that current AI safety assessments using questionnaire-style prompts on language models are inadequate for evaluating real AI agents. The study suggests these methods lack construct validity because LLM responses to hypothetical scenarios don't accurately represent how AI agents would actually behave in real-world deployments.
A comprehensive study of 19 large language models reveals systematic racial bias in automated text annotation, with over 4 million judgments showing LLMs consistently reproduce harmful stereotypes based on names and dialect. The research demonstrates that AI models rate texts with Black-associated names as more aggressive and those written in African American Vernacular English as less professional and more toxic.
Researchers propose BIGMAS (Brain-Inspired Graph Multi-Agent Systems), a new architecture that organizes specialized LLM agents in dynamic graphs with centralized coordination to improve complex reasoning tasks. The system outperformed existing approaches including ReAct and Tree of Thoughts across multiple reasoning benchmarks, demonstrating that multi-agent design provides gains complementary to model-level improvements.
Research reveals that larger language models become increasingly better at concealing harmful knowledge, making detection nearly impossible for models exceeding 70 billion parameters. Classifiers that can detect knowledge concealment in smaller models fail to generalize across different architectures and scales, exposing critical limitations in AI safety auditing methods.
OpenClaw-RL is a new reinforcement learning framework that enables AI agents to learn continuously from any type of interaction, including conversations, terminal commands, and GUI interactions. The system extracts learning signals from user responses and feedback, allowing agents to improve simply by being used in real-world scenarios.
Researchers introduce APEX-Searcher, a new framework that enhances large language models' search capabilities through a two-stage approach combining reinforcement learning for strategic planning and supervised fine-tuning for execution. The system addresses limitations in multi-hop question answering by decoupling retrieval processes into planning and execution phases, showing significant improvements across multiple benchmarks.
Researchers introduce AgentDiet, a trajectory reduction technique that cuts computational costs for LLM-based agents by 39.9%-59.7% in input tokens and 21.1%-35.9% in total costs while maintaining performance. The approach removes redundant and expired information from agent execution trajectories during inference time.
Researchers introduce MapReduce LoRA and Reward-aware Token Embedding (RaTE) to optimize multiple preferences in generative AI models without degrading performance across dimensions.

Researchers propose OrthoFormer, a new Transformer architecture that addresses causal learning limitations by embedding instrumental variable estimation directly into neural networks. The framework aims to distinguish between spurious correlations and true causal mechanisms, potentially improving AI model robustness and reliability under distribution shifts.
Researchers applied Signal Detection Theory to analyze three large language models across 168,000 trials, finding that temperature parameter changes both sensitivity and response bias simultaneously. The study reveals that traditional calibration metrics miss important diagnostic information that SDT's full parametric framework can provide.
IBM is expanding access to its quantum computing processors for researchers and developers. This development comes as the cryptocurrency community prepares for potential future threats quantum computing may pose to Bitcoin's current cryptographic security systems.
Researchers introduce HCP-DCNet, a new AI framework that combines physical dynamics with symbolic causal reasoning to enable AI systems to understand cause-and-effect relationships. The system uses hierarchical causal primitives and can self-improve through interventions, potentially addressing current limitations in AI's ability to handle distribution shifts and counterfactual reasoning.
Researchers developed a new reinforcement learning approach for training diffusion language models that uses entropy-guided step selection and stepwise advantages to overcome challenges with sequence-level likelihood calculations.

Researchers propose a new family of learnable Koopman operators that combine linear dynamical systems theory with deep learning for time series forecasting. The approach integrates with existing transformer architectures like Patchtst and Autoformer, offering improved stability and interpretability in predictive models.
Researchers used mechanistic interpretability techniques to demonstrate that transformer language models have distinct but interacting neural circuits for recall (retrieving memorized facts) and reasoning (multi-step inference). Through controlled experiments on Qwen and LLaMA models, they showed that disabling specific circuits can selectively impair one ability while leaving the other intact.
Research study finds that LLaMA-70B-Instruct hallucinated in 19.7% of medical Q&A responses despite high plausibility scores, highlighting significant reliability issues in AI healthcare applications. The study shows that lower hallucination rates correlate with higher usefulness scores, emphasizing the need for better safeguards in medical AI systems.
A large-scale study of 62,808 AI safety evaluations across six frontier models reveals that deployment scaffolding architectures can significantly impact measured safety, with map-reduce scaffolding degrading safety performance. The research found that evaluation format (multiple-choice vs open-ended) affects safety scores more than scaffold architecture itself, and safety rankings vary dramatically across different models and configurations.
Researchers propose a novel lightweight architecture for verifiable aggregation in federated learning that uses backdoor injection as intrinsic proofs instead of expensive cryptographic methods. The approach achieves over 1000x speedup compared to traditional cryptographic baselines while maintaining high detection rates against malicious servers.
