Matrix multiplication provides a series of fast multiply and add operations in parallel, and it is built into the hardware of GPUs and AI processing cores (see Tensor core). See compute-in-memory.

You may have seen the “no-lift pencil” puzzles online — challenges that ask you to draw a shape without lifting your pencil ...

Part of the process of running LLMs involves performing matrix multiplication (MatMul), where data is combined with weights in neural networks to provide likely best answers to queries.
