Researchers introduced NeuroCognition, a new benchmark for evaluating LLMs based on neuropsychological tests, revealing that while models show unified capability across tasks, they struggle with foundational cognitive abilities. The study found LLMs perform well on text but degrade with images and complexity, suggesting current models lack core adaptive cognition compared to human intelligence.
Researchers analyzed memory systems in LLM agents and found that retrieval methods are more critical than write strategies for performance. Simple raw chunk storage matched expensive alternatives, suggesting current memory pipelines may discard useful context that retrieval systems cannot compensate for.
