 Effectively, allowing the RNN network to run like a transformer network, when rolled out side by side. Where it can be trained "like a transformer" and "executed like an RNN" (the best of both worlds)

+> Note the cascading digram is the theorectical optimal, in practise some trainers and/or inference implementation may batch the cascade to chunks of tokens (32/64/128/256/512), to reduce VRAM lookup and usage, and improve overall performance.
 
 ## What is channel / time mixing, explain it in simple terms?
