Why Low-Precision Transformer Training Fails: Research Explains Flash Attention Instability
A new paper from researchers Qiu and Yao provides the first mechanistic explanation of why low-precision training with flash attention fails catastrophically. The authors identify two intertwined phenomena—emergent low-rank representations and biased rounding errors—and introduce a minimal modification that stabilizes training.
