DeepSeek has released V4.1-Flash, the smallest model in its new architecture family, featuring native visual understanding and designed for greater capability, faster inference, and higher throughput. Asymmetric Architecture Delivers Efficiency V4.1-Flash is a 552-parameter mixture-of-experts (MoE) model built on a new Causal Encoder–Decoder architecture that uses just 8 billion active parameters for input processing and 16 billion for output generation. The model combines new pretraining methods with larger-scale reinforcement learning post-training to achieve benchmark results that exceed...
