IBM Research announced the world's first sub-1 nanometer chip technology at the 0.7nm node on June 25, 2026, using a vertically stacked 3D nanosheet architecture called 'nanostack' to overcome quantum…
A new technique called Flash Attention uses tiled attention to fit the N×N attention matrix into SRAM, reducing memory reads/writes and speeding up self-attention in transformers.…
A technical analysis calculates the dollar cost per user for serving large language models at scale using napkin math, breaking down GPU resources, matrix multiplication costs, and attention mechanism…
A developer implemented FlashAttention's forward and backward passes from scratch in pure CUDA C++, achieving O(N) memory complexity through manual SRAM tiling and online softmax recurrence. A rejecte…
