This approach maintains model coherency while enabling precise persona and style control, offering a more efficient alternative to fine-tuning.
Researchers benchmarked state-of-the-art LLMs for detecting vulnerabilities in Solidity smart contracts using zero-shot prompting strategies.

Justitia is a new scheduling system for task-parallel LLM agents that optimizes GPU server performance through selective resource allocation based on completion order prediction. The system uses memory-centric cost quantification and virtual-time fair queuing to achieve both efficiency and fairness in LLM serving environments.
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.

Researchers at NVIDIA developed NEMOTRON-CROSSTHINK, a new AI framework that uses reinforcement learning with multi-domain data to improve language model reasoning across diverse fields beyond just mathematics. The system shows significant performance improvements on both mathematical and non-mathematical reasoning benchmarks while using 28% fewer tokens for correct answers.
A research paper argues that the most valuable capabilities of large language models are precisely those that cannot be captured by human-readable rules. The thesis is supported by proof showing that if LLM capabilities could be fully rule-encoded, they would be equivalent to expert systems, which have been proven historically weaker than LLMs.

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 identify a fundamental flaw in large language models called 'Rung Collapse' where AI systems achieve correct answers through flawed causal reasoning that fails under distribution shifts.

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 propose Simple Energy Adaptation (SEA), a new algorithm for aligning large language models with human feedback at inference time.

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.
Researchers evaluated the faithfulness of closed-source AI models like ChatGPT and Gemini in medical reasoning, finding that their explanations often appear plausible but don't reflect actual reasoning processes. The study revealed these models frequently incorporate external hints without acknowledgment and their chain-of-thought reasoning doesn't causally drive predictions, raising safety concerns for medical applications.
Researchers introduce CCTU, a new benchmark for evaluating large language models' ability to use tools under complex constraints. The study reveals that even state-of-the-art LLMs achieve less than 20% task completion rates when strict constraint adherence is required, with models violating constraints in over 50% of cases.
Researchers introduce Mixture-of-Depths Attention (MoDA), a new mechanism for large language models that allows attention heads to access key-value pairs from both current and preceding layers to combat signal degradation in deeper models.
