• TriCalRAG: A Three-Strategy, Retrieval-Augmented Benchmark for On-Premise LLM-Based Root Cause Analysis in AIOps — TriCalRAG shows RAG over labeled incident history improves on-premise LLM root cause analysis F1 by 0.10–0.27 and eliminates the near-degenerate behavior where zero-shot models predict 'anomaly' on 100% of incidents; batching scales throughput 41x and 4-bit quantization cuts latency 20% with no accuracy loss on a single RTX PRO 6000.
• NeuroActiSep: Detecting Factual Hallucinations from Feed-Forward Neurons in a Single Pass — NeuroActiSep identifies feed-forward neurons correlated with factual hallucinations at the final prompt token and shows their identities transfer across QA datasets — offering a single-pass hallucination detector that performs on par with probes trained on full internal state representations.
• SeqMoE: Toward Full-Load Performance via Predictive and Graph-Compatible MoE Offloading — SeqMoE achieves 96.97% expert hit rate and 80.22% of full-load inference performance while keeping only 45% of MoE expert weights in device memory, using sequence-to-sequence prediction for expert prefetching — making large Mixture-of-Experts models practical on memory-constrained hardware.
• Sympathetic Framing: Evaluating AI Alignment across Sociodemographic Groups — A large-scale study using 3,011 representative UK adults and 7 LLMs finds GPT-5.2 achieves 0.789 correlation with human emotional responses to political news headlines while Mistral Large 2512 scores only 0.4—leading models align broadly across demographic groups, but statistically significant inter-group differences persist even at high aggregate scores.
• Nvidia and Palantir team up to run supply chains with AI, starting with Nvidia's own million-part operation — Nvidia and Palantir are using Nvidia's own million-part supply chain as the first live testbed for an AI stack combining Nemotron models, Palantir Foundry, and Nvidia cuOpt — targeting bottleneck detection and autonomous material allocation.
• Distribution-Consistent Inference for Dynamic Sparse Mixture-of-Experts — EMNLP 2026 paper introduces Layer-wise Distribution Alignment (LDA), a calibration-based inference-time fix for Sparse MoE models that recovers most accuracy lost when using fewer active experts—no retraining required, negligible overhead.
• Samsung taps Mistral AI models for semiconductor manufacturing — Samsung has partnered with Mistral AI to deploy on-premises Mistral Large across its semiconductor fabs, announced at the South Korea–France bilateral summit in Paris; Samsung also led Mistral's Series D funding round to secure a strategic equity stake.
• Bait-and-Recover: Poisoning Internal Refusal Signals to Defend LLMs against White-Box Editing Jailbreaks — Bait-and-Recover defeats white-box representation engineering attacks on open-weight LLMs by poisoning the observation path: a bait adapter corrupts the signal attackers measure, a recovery adapter restores clean computation, raising minimum refusal rate from 16.25% to 71.75% with negligible capability loss.
• ACE: Adapter Consolidation across Experts for Parameter-Efficient Fine-Tuning of MoE LLMs — ACE replaces per-expert LoRA adapters in mixture-of-experts LLMs with group-shared higher-rank modules, achieving the highest accuracy among parameter-matched PEFT methods on 3 of 4 MoE backbones while delivering 1.31–1.48× training speedup with no memory increase.
• We're Cooked! - Probing LLM Political Alignment Via Conflict-Framed Recipe Translation — A fully-crossed factorial study of 15,680 responses across 8 LLMs and 17 languages finds that a single politically charged framing word — 'aggressor', 'coloniser' — is enough to shift how models resolve ambiguous translation tasks, with Western, Chinese, and European models clustering into distinct behavioral profiles.
