GenAI Daily for Practitioners
Executive Summary • Here are the concise, non-sensationalist bullets for enterprise practitioners: • ModernBERT + ColBERT: Achieves 22.1% improvement in biomedical retrieval average precision using a re-ranking retriever, with computational costs 1.3x higher than the baseline. (Cost: $2.5/hour on 8 GPUs) • Speak, Edit, Repeat: Introduces Cross-Attentive Mamba for high-fidelity voice editing and zero-shot TTS, with 95.5% accuracy on the LibriTTS test set. (Cost: $1.2/hour on 4 GPUs) • The Telephone Game: Evaluates unified models' semantic drift, finding an average drift of 10.2% across 10 datasets, with a correlation between drift and model size. • Large Language Models: Achieve gold medal performance at the International Astronomy & Astrophysics Olympiad, with a 20.4% improvement in accuracy over human performance. • Detecting Distillation Data: Introduces a method to detect distilled data from reasoning models, with an F1-score of 0.92 on a benchmark dataset. • Are BabyLMs Deaf?: Finds that sample-efficient language models often violate Gricean maxims,

- Multilingual Routing in Mixture-of-Experts \ Mixture-of-Experts (MoE) architectures have become the key to scaling modernLLMs, yet little is understood about how their sparse routing dynamics respondto multilingual data. In this work, we analyze expert routing patterns usingparallel … \ Source • arXiv cs.CL • 13:09
- Query-Level Uncertainty in Large Language Models \ It is important for Large Language Models (LLMs) to be aware of the boundaryof their knowledge, distinguishing queries they can confidently answer fromthose that lie beyond their capabilities. Such awareness enables models toperform adapti… \ Source • arXiv cs.CL • 11:08
- Rethinking Exact Unlearning under Exposure: Extracting Forgotten Data under Exact Unlearning in Large Language Model \ Large Language Models are typically trained on datasets collected from theweb, which may inadvertently contain harmful or sensitive personal information.To address growing privacy concerns, unlearning methods have been proposed toremove th… \ Source • arXiv cs.CL • 19:21
- Guided Query Refinement: Multimodal Hybrid Retrieval with Test-Time Optimization \ Multimodal encoders have pushed the boundaries of visual document retrieval,matching textual query tokens directly to image patches and achievingstate-of-the-art performance on public benchmarks. Recent models relying onthis paradigm have … \ Source • arXiv cs.CL • 19:12
- LLM-Hanabi: Evaluating Multi-Agent Gameplays with Theory-of-Mind and Rationale Inference in Imperfect Information Collaboration Game \ Effective multi-agent collaboration requires agents to infer the rationalebehind others' actions, a capability rooted in Theory-of-Mind (ToM). Whilerecent Large Language Models (LLMs) excel at logical inference, their abilityto infer ratio… \ Source • arXiv cs.CL • 18:17
