To give more credit, I know your company was working on your own optimizations, which are prior art. It's possible that you made a 180 GB/s shader on your own (quite slow compared to my 319 GB/s). Or that the 319 GB/s was used, but the self-attention bottleneck was non-negligible.

However, for whatever reason, when Greg Gerganov started work on the Metal backend, you made a product announcement almost a day later. That seems like a non-coincidence and there must be some logical explanation.
