It's a generic comment that I don't think is even specifically about Kimi Linear or this submission, you could leave the same comment on almost any AI/ML submission and it'd say the same amount and be as relevant/irrelevant.
Agreed it would apply to any method or system that improved on efficiency.
It doesn't diminish the feat. Not trying to minimize the impact of Kimi linear's gain. It is a novel and outstanding benefit applicable to LLMs.
