Running open-weight models locally: Kimi K3.1 needs 594GB, ~$38k for 15 tok/s

After months of benchmarking every new open-weight model (Kimi K3.1, DeepSeek V4.1 Flash, MiniMax M3.1), the author maps what local deployment actually takes: hardware needs, single-machine vs cluster performance, and when cloud compute wins — plus one-shot coding tests vs frontier models.

Kimi K3.1: a 512GB Mac Studio ($9.5k) doesn't fit (594GB minimum); four linked studios ($38k) yield 15 tok/s; AntSeed cloud 24 tok/s. Kimi K3.1 Pro weights alone are 1.56TB, needing four maxed M5 Ultra studios ($91k) just for memory.
