antirez hits 25 tok/s running DeepSeek v4.1 Flash across two M5 Max MacBooks via RDMA
antirez · x · 2026-09-11
- antirez reports running DeepSeek v4.1 Flash on a 128GB M5 Max with DwarfStar's SSD streaming: 15 tok/s on a single machine, helped by recent SSD-streaming changes that retain the right experts (and possibly higher expert reuse in DS4.1).
- With tensor parallelism split 50/50 across two MacBooks over RDMA, throughput rises to 25 tok/s. He notes this use case could likely be optimized much further and will push the setup online when ready.
