FlashOptim: Optimizers for Memory Efficient Training

FlashOptim introduces memory optimization techniques that reduce AI training memory requirements by over 50% per parameter while maintaining model quality. The suite reduces AdamW memory usage from 16 bytes to 7 bytes per parameter through improved master weight splitting and 8-bit optimizer state quantization.

Optimizer-Induced Low-Dimensional Drift and Transverse Dynamics in Transformer Training

Researchers analyzed training trajectories in small transformer models, finding that parameter updates organize into a dominant drift direction with transverse dynamics. The study reveals that different optimizers (AdamW vs SGD) create substantially different trajectory geometries, with AdamW developing multi-dimensional structures while SGD produces more linear evolution.
