DeepSeek V4 Flash 0731deepseek/deepseek-v4-flash-0731

DeepSeek V4 Flash is a previous-generation text MoE model. DeepSeek retired the V4 Flash API on September 10, 2026. The legacy deepseek-v4-flash alias temporarily invokes V4.1 Flash, so it no longer identifies the original V4 model. The historical model page and weights reference are retained.
