Analyzing Kimi K3 Attention: Delta Attention and Residuals
AndLukyane · x · 2026-07-31
The author provides a technical breakdown of the attention mechanism in the newly released Kimi K3 paper. Kimi utilizes Kimi Delta Attention and Attention Residuals, which originally appeared in Kimi Linear and are essentially variations of linear or hybrid attention.
The author integrated these insights into personal Obsidian notes, supplementing them with detailed derivations of underlying principles ranging from basic word embeddings to Transformer scaled dot-product attention.
