User reports 8-22 t/s on a 32GB M4 MacBook Air with 21GB of allocations. Setup is a custom inference engine called Cherenkov that combines predictive expert streaming with optional mixed-precision execution, keeping a bounded working set of experts in unified memory rather than loading the entire model. A one-layer lookahead predicts which experts will be needed next and initiates SSD reads.
