Capability
2 medium confidenceFlashKDA provides forward and backward CUTLASS kernels for one linear-attention variant, Kimi Delta Attention, purpose-built for Moonshot AI's Kimi model family rather than a broad attention technique. That single-model, single-variant scope is well short of a production engine such as TensorRT.
