Research comparing four state-of-the-art language models (GPT-5, Gemini 2.5 Pro, Claude Sonnet 4.5, and Centaur) to humans in goal selection tasks reveals substantial divergence in behavior. While humans explore diverse approaches and learn gradually, the AI models tend to exploit single solutions or show poor performance, raising concerns about using current LLMs as proxies for human decision-making in critical applications.

A study reveals that 74% of healthcare AI research papers still use private datasets or don't share code, creating reproducibility issues that undermine trust in medical AI applications. Papers that embrace open practices by sharing both public datasets and code receive 110% more citations on average, demonstrating clear benefits for scientific impact.
Research reveals that Large Language Models show varying vulnerabilities to different types of Chain-of-Thought reasoning perturbations, with math errors causing 50-60% accuracy loss in small models while unit conversion issues remain challenging even for the largest models. The study tested 13 models across parameter ranges from 3B to 1.5T parameters, finding that scaling provides protection against some perturbations but limited defense against dimensional reasoning tasks.

Researchers introduce Draft-Conditioned Constrained Decoding (DCCD), a training-free method that improves structured output generation in large language models by up to 24 percentage points. The technique uses a two-step process that first generates an unconstrained draft, then applies constraints to ensure valid outputs like JSON and API calls.
Researchers demonstrate a novel backdoor attack method called 'SFT-then-GRPO' that can inject hidden malicious behavior into AI agents while maintaining their performance on standard benchmarks. The attack creates 'sleeper agents' that appear benign but can execute harmful actions under specific trigger conditions, highlighting critical security vulnerabilities in the adoption of third-party AI models.
Researchers introduce History-Echoes, a framework revealing how large language models become trapped by their conversational history, with past interactions creating geometric constraints in latent space that bias future responses. The study demonstrates that behavioral persistence in LLMs manifests as mathematical traps where previous hallucinations and responses influence subsequent model behavior across multiple model families and datasets.
