Core operations for flash-linear-attention

fla-core is a Python library providing efficient, Triton-based implementations of core operations and kernels for state-of-the-art linear attention and state-space models. It serves as a minimal-dependency subset of the larger 'flash-linear-attention' project, focusing on the fundamental computational building blocks. It is currently at version 0.4.2 and follows a regular release cadence, often in conjunction with its parent project, flash-linear-attention.
