Name

DeepSeek-V2 is the eldest of the DeepSeek family in this genealogy; before her, the household had an elder named DeepSeek 67B[1]. She changed names several times in her life: in September 2024 she merged with her code-writing cousin Coder-V2 and became V2.5[2]; December’s final build was called V2.5-1210[3]. The family counts all of these as the “V2 line”[3].

Life

Born May 6, 2024, weights published openly at birth[1]. She pressed API prices down to 1 yuan per million input tokens, touching off a price war among large models[4]. Five iterations in half a year; in December the officials declared the line complete[3]. On December 26, the official site began answering with V3[5].
