All‑AMD AI training, proven at scale

Researchers ran the first large-scale mixture‑of‑experts (MoE) pretraining entirely on AMD hardware—MI300X GPUs connected via Pollara—and distilled practical playbooks for both systems and model design.

Systems: Full-cluster networking benchmarks for all-reduce, reduce-scatter, all-gather, and broadcast across message sizes and GPU counts; MI300X kernel sizing and memory-bandwidth insights; a production-ready training stack with fault tolerance and checkpoint reshaping.
Modeling: MI300X‑aware sizing rules for attention and MLP blocks, plus MoE width choices that balance training throughput with inference latency.
Results: Introduces ZAYA1 (760M active, 8.3B total parameters, MoE). At this scale it matches Qwen3‑4B and Gemma3‑12B, and outperforms Llama‑3‑8B and OLMoE on reasoning, math, and coding benchmarks.

Takeaway: AMD’s compute, network, and software stack are mature and optimized enough for competitive large‑scale pretraining—expanding hardware choice for frontier AI.

Meet GRACE: a moral governor for safer, more transparent AI

AI agents are getting powerful—so how do we make sure they do the right thing, not just the effective thing? Meet GRACE, a reason-based moral governor that keeps AI behavior aligned with human norms by separating moral reasoning from goal-driven decision-making. * Moral Module: uses deontic logic and explicit reasons

Why some fine-tuned LLMs miss phishing—and how to fix it

Not all fine-tuned LLMs spot phishing equally. A new study tests Llama 3.1 8B, Gemma 2 9B, and Mistral on high-stakes phishing detection—and uses SHAP and mechanistic interpretability to reveal why models do (or don’t) generalize. * Architecture × data diversity matters: Gemma 2 9B hits state-of-the-art performance (F1

AI that explains itself—by following the science

AI that explains itself—by following the science Black-box AI can be powerful, but it often can’t tell us why it made a decision. Concept Bottleneck Models (CBMs) try to fix that by predicting human-understandable concepts first, then the final answer. The catch: standard CBMs ignore domain-specific cause-and-effect and

Meet GenomAgent: A Team of AI Specialists for Smarter Genomics Q&A

TL;DR: Finding reliable answers in genomics is hard. GenomAgent turns one big AI into a coordinating team of specialists—and beats the current leader by 12% on a key benchmark. Genomic facts live across many databases. Standard chatbots struggle because they can’t flexibly query those sources. GeneGPT added
