Kimi K3 Architectural Innovations Spark Debate

Reposts and comments emphasize that Kimi K3 isn't just a simple "distilled version" but features substantial architectural innovations:
- KDA hybrid linear attention: For more efficient long-context scaling.
- Attention Residuals: Described as a more efficient memory retrieval mechanism.
- Stable LatentMoE: Activates only about 1.8% of experts at a time.
- Quantile-balanced routing: Used for inference/infrastructure-level optimizations.
The post also mentions its 2.8T scale, branding it as "one of the world's largest open-weight models," and highlights it as a new paradigm of "co-designing architecture, training, serving, and agents."
