Story summary

Researchers from the Massachusetts Institute of Technology, Northeastern University, and Meta report that large language models may prioritize sentence structure over meaning.
Testing with grammatically correct, nonsensical prompts shows models overrelying on structure, misinterpreting semantics.
The team is led by Chantal Shaib (Massachusetts Institute of Technology) and Vinith M. Suriyakumar (Northeastern University).
They will present at NeurIPS later this month.
