DeepSeek V4.1 Flash Architecture: The State Lifecycle Behind 1M Context

This article dissects DeepSeek V4.1 Flash's architecture for 1M-token context, explaining how CED reduces prefill compute, CSA2 shares global KV across layers, hierarchical sparse indexing narrows search, FP4 quantization shrinks storage, SWA uses bounded replay for recovery, and Engram adds a conditional memory path—revealing five cost dimensions of long-context deployment.

DeepSeek-V4.1-Flash: 8B Activated Model Beats 1.6T V4-Pro, Local Deployment Tested

DeepSeek-V4.1-Flash open-sourced with CED architecture and 8B/16B activated parameters outperforms its 1.6T predecessor V4-Pro on coding benchmarks, approaches GPT-6 Astra on DeepSWE, but requires 510GB FP8 weights needing 8×H200 for full-context local deployment; author tests across six harnesses finding Claude Code/Codex integration near peak performance.
