Rumored Local Benchmarks for Kimi K3

Stefania_druga · x · 2026-07-18

The repost speculates on the local deployment requirements for Kimi K3: based on rumored parameter counts, it might take 4 512GB M3 Ultra Mac Studios to run, totaling around 2TB of memory, paired with MTP + Tensor Parallelism and utilizing RDMA over Thunderbolt 5 for parallel processing.

The original post also mentions that once the weights are available, the author will release full benchmarks on their local platform. Currently, based on rumor-based estimates, they believe it could achieve 30+ tok/s locally, with slower forward prefilling. However, if a 512GB M5 Ultra is released in the future, prefill speeds could increase by roughly 5x.
