The video explains why DeepSeek’s V4.1 Flash is a major architectural breakthrough rather than a routine model update. Its central achievement is making long-context AI dramatically cheaper by reducing the KV-cache memory required per token to just 890 bytes, down from 3.5 MB in V4 Flash and far smaller than earlier DeepSeek models.
