DeepSeek v4.1 Flash uses dual active parameter counts for input and output

By PulseAugur Editorial · [1 sources] ·

The DeepSeek v4.1 Flash model reportedly utilizes two distinct active parameter counts: 8 billion for input processing and 16 billion for output generation. This unique architecture, which separates prefill and decoding parameters, is a topic of discussion within the AI community. The implications of this approach and its potential adoption by other models are being explored. AI

IMPACT This architectural choice could influence future model designs and performance optimizations.
