Rumored spec sheet

Pulled from the third-party explainer pages at deepseekv4.dev and deepseek-v4.ai:

• ~1 Trillion parameters in a Mixture-of-Experts (MoE) layout.
• Engram Memory Core — described as "conditional O(1) memory lookup" for persistent recall.
• mHC Hyper-Connections Reasoning — a new information-flow primitive aimed at multi-step reasoning.
• 1M+ token context window — long-context positioning for repo-level code and long-document work.
• Efficiency: "around 40% lower memory use and up to 1.8x faster inference" vs earlier architectures.

Multimodal & workflow positioning

From deepseekv4.dev:

"Understand words, visuals, and voice together." "Designed to hold much larger context so long documents stay connected." "Turn repeatable tasks into reliable workflows."

Positioned for repo-level coding, long-context reasoning, and agentic workflows, with an SDK + sandbox integration path and planned enterprise governance controls.
