Hardware requirements

What hardware do I need to run Kimi K3 2.8T-A104B?

2780B MoE · 104B active 1024K context Modified MIT New this month

At Q4_K_M the weights are 1563.2 GB; with an 8K KV cache and runtime overhead that is 1564.0 GB, so it wants more memory than any single card we list to run with headroom. Every figure below is computed from the model’s published shape against each device’s usable memory; tokens per second are estimates. The method.

Minimum practical Nothing in the catalogue

No single device we list clears this bar — this is a multi-GPU or server-class model.

Recommended Nothing in the catalogue

No single device we list clears this bar — this is a multi-GPU or server-class model.

High quality Nothing in the catalogue

No single device we list clears this bar — this is a multi-GPU or server-class model.

Long context Nothing in the catalogue

No single device we list clears this bar — this is a multi-GPU or server-class model.

Apple Silicon Nothing in the catalogue

No single device we list clears this bar — this is a multi-GPU or server-class model.

CPU only Nothing in the catalogue

Too large for any CPU configuration we list.

Totals add 0.6 GB runtime overhead and an f16 KV cache; "needs" is the smallest discrete card class whose usable memory (after display and driver reserve) leaves 15% headroom. A q8_0 cache roughly halves the KV columns.
