Automatic FlashAttention Kernel Synthesis via SQL Extensions
October 30, 2026
A new system deduces FlashAttention kernels from ~25 lines of vanilla SQL. The approach utilizes xarray-sql for petabyte-scale array representation, ddx for JAX-style automatic differentiation in SQL, and the einfold modular query planner.
