DeepSeek V4 Architecture

DeepSeek Engram Memory

The secret weapon behind DeepSeek V4's infinite context window.

What is Engram?

Traditional LLMs suffer from "KV Cache" bottlenecks, limiting their context to fixed sizes (e.g. 128k). Engram Memory introduces a novel "Conditional Memory via Scalable Lookup" mechanism.

It acts like a human hippocampus, storing infinite "memory traces" (Engrams) effectively decoupling compute from memory capacity.
