Paraphrase Brittleness in Production Retrieval-Augmented Commercial Recommendation: Reproducibility Below the Rerun-Stability Baseline

Research reveals that AI recommendation systems exhibit severe brittleness when processing paraphrased queries, with recommendation-set similarity dropping to 0.288 for cosmetic rewordings and 0.135 for constraint-modified queries—far below the 0.50-0.61 baseline for identical prompts. This undermines the reliability of AI visibility tracking metrics used in commercial recommendation optimization, as brand mention frequency depends more on prompt phrasing than actual model behavior.

Benchmarks for Vision-Language Models in Urban Perception Should Be Reliability-Aware and Negotiated

Researchers argue that benchmarking vision-language models for urban perception tasks must account for human disagreement and measurement reliability rather than treating consensus as ground truth. A study of seven VLMs evaluated on 100 Montreal street scenes reveals that model performance correlates with inter-annotator reliability, highlighting the need for transparent uncertainty reporting in AI evaluation frameworks.
