Benjamin Warner @benjaminwarner.dev · Dec 22 How did we do it? First, we brought all the modern LLM architectural improvements to encoders, including alternating global & local attention, RoPE, and GeGLU layers, and added full model unpadding using Flash Attention for maximum performance (illustrated in the next post).

Second, we carefully designed ModernBERT's architecture run to efficiently across most common GPUs. Many common older models don't consider the hardware they will run on and are slower than they should be. Not so with ModernBERT. (Full model sequence packing illustrated below)
