BioDivergence is a benchmark and evaluation framework for hidden contextual contradictions in biomedical abstracts. It proposes a six-class conflict taxonomy, a 13-axis divergence ontology, and four structured outputs per claim pair. The silver benchmark contains 11,865 claim pairs across five biomedical domains. Mistral-7B-Instruct-v0.3 achieves 0.5523 accuracy and 0.3894 contextual-F1.
Experiment on 120 tasks testing whether weaker models match frontier models on high-verifiability tasks (Karpathy framework). Claude Sonnet 4.6, GPT 5.5, Mistral 3 8B compared. Code/structured extraction: narrower gaps with retry (Mistral 87%→95% code). Multi-hop reasoning: real capability gap (Sonnet 78%, Mistral 51%). Creative summarization: expected advantage for stronger models.
GuardNet is a guardrail system using an ensemble of shallow neural networks (BiLSTMs, 47M parameters) to detect prompt injection and jailbreak attacks on LLMs. The approach prioritizes diversity of example coverage and threshold calibration over model scale.
