Closing the Activation-Cone Blind Spot: Response-Time Probing and Unified Defense

Evaluates five jailbreak-defense paradigms across seven instruction-tuned models (7B-31B) and five attack families, proving that prompt-time activation defenses are structurally blind to prefilling attacks. Introduces response-time probing on the first generated tokens (AUROC 0.97-1.00 across all models); composed with null-space steering, it drives prefilling attack success to zero with no false positives on benign inputs. Code, attacks, and per-sample results released.

Cross-Generational Transfer of Adversarial Attacks Reveals Non-Monotonic Safety Alignment in LLMs

An automated red-teaming study finding that LLM safety alignment does not always improve monotonically across model generations. Using quality-diversity evolution (MAP-Elites) to probe successive generations of an open-weight model family, it shows that a mid-generation release can be more vulnerable than both its predecessor and its successor, with evolved attack archives transferring unevenly across generations. These longitudinal patterns are invisible to static benchmarks and surface only through adaptive, longitudinal probing.

Cross-Platform Fused MoE Dispatch in Triton: Portable Expert Routing Without CUDA

TritonMoE, a Mixture-of-Experts inference kernel written entirely in OpenAI Triton with no CUDA. A fused gate+up GEMM computes both SwiGLU projections from shared tile loads, eliminating 35% of global memory traffic. Reaches 89-131% of Megablocks throughput at inference batch sizes (up to 512 tokens) on both NVIDIA A100 and AMD MI300X, with full code portability across vendors.

Spark-LLM-Eval: A Distributed Framework for Statistically Rigorous Large Language Model Evaluation

A distributed framework leveraging Apache Spark for statistically rigorous LLM evaluation at scale. Treats evaluation as a data-parallel problem, providing bootstrap confidence intervals, statistical significance tests (paired t-tests, McNemar's test, Wilcoxon signed-rank), and content-addressable response caching backed by Delta Lake. Reports linear scaling performance.
