Kimi K3 Architecture Trail in motion

This short video summarizes the page: the source set, the decision boundary and the practical next action.

Kimi K3 Architecture Trail visual summary
01

Kimi Delta Attention is the key architecture thread

The Kimi Linear paper introduces KDA and reports up to 75% KV-cache reduction and up to 6x decoding throughput at 1M context in the paper setting. The K3 page points to KDA as part of the model architecture.

01 · KDA Read KDA as a research lineage, not as a standalone deployment promise for K3 weights.
02

Attention Residuals explain the other named component

The Attention Residuals paper and repository describe cross-layer attention for reducing information dilution in deep PreNorm models, plus Block AttnRes for large-scale training efficiency.

02 · AttnRes The diagram pairs deep-layer signal flow with the official repository and paper.
03

FlashKDA is the implementation bridge

FlashKDA is an official MoonshotAI kernel repository. It is useful for understanding engineering direction, and it becomes more important after official K3 weights and inference notes can be verified.

03 · FlashKDA Kernel, model-hosting and vLLM support should be revisited when official weights are published.
Architecture map

Trace the named K3 components

The map links KDA, Attention Residuals and FlashKDA to the supporting paper or official implementation source.

KDA comes from Kimi Linear and is the main attention-efficiency thread referenced by K3 materials.
