Why it matters
Explains how Moonshot AI keeps a 2.8T-parameter model deployable via LatentMoE compression, a KV-cache-capping hybrid attention scheme, and aggressive quantization down to community 1-2 bit GGUF — concrete architectural patterns engineers building large MoE systems can study and reuse.
An analysis of Moonshot AI's Kimi K3, a 2.8-trillion-parameter multimodal MoE model with only ~104B active parameters per token and a 1M-token context window.
It details the engineering that makes such scale deployable: LatentMoE compression for expert routing, a hybrid Kimi Delta/Gated Latent Attention scheme that caps KV-cache growth, and FP4/FP8 quantization-aware training (with community 1-2 bit GGUF compression) that shrinks the model far below its raw BF16 footprint while preserving reasoning quality.
