ZAYA1-8B Technical Report

Robert Washbourne, Rishi Iyer, Tomas Figliolia +15

We present ZAYA1-8B, a reasoning-focused mixture-of-experts (MoE) model with 700M active and 8B total parameters, built on Zyphra's MoE++ architecture. ZAYA1-8B's core pretraining,…

Compressed Convolutional Attention: Efficient Attention in a Compressed Latent Space

Tomas Figliolia, Nicholas Alonso, Rishi Iyer +2

Multi-headed Attention's (MHA) quadratic compute and linearly growing KV-cache make long-context transformers expensive to train and serve. Prior works such as Grouped Query Attent…

Training Foundation Models on a Full-Stack AMD Platform: Compute, Networking, and System Design

Quentin Anthony, Yury Tokpanov, Skyler Szot +18

We report on the first large-scale mixture-of-experts (MoE) pretraining study on pure AMD hardware, utilizing both MI300X GPUs and Pollara networking. We distill practical guidance…

Tree Attention: Topology-aware Decoding for Long-Context Attention on GPU clusters

Vasudev Shyam, Jonathan Pilault, Emily Shepperd +2

Our formulation reveals that the reduction across the sequence axis can be efficiently computed in parallel through a tree reduction. Our algorithm, called Tree Attention, for para…
