ion matrices into a single matrix and perform the projection in one step. This increases the size of the matrix multiplications of the input projections and improves the impact of quantization. You can combine the projection matrices with just a single line of code:   Copied pipe.fuse_qkv_projections() This provides a minor improvement from 2.54 seconds to 2.52 seconds.  Support for fuse_qkv_projections() is limited and experimental. It’s not a
