DeepSeek-V4 MoE SOTA OSS 1M Ctx Efficiency Boom

Key Questions

What is DeepSeek-V4-Pro?

DeepSeek-V4-Pro is a 1.6T/284B-49B active MoE model with 1M context, using 27% FLOPs and 10% KV via hybrid CSA+HCA attention. It tops coding, math, agentic, and long-ctx benchmarks on HF OSS.

How efficient is DeepSeek-V4?

It achieves high efficiency with reduced FLOPs and KV cache, making it ideal for RAG, agents, and production latency/cost. Pro-Max nears closed SOTA performance.

What makes DeepSeek-V4 a SOTA OSS model?

It excels in million-token context intelligence, outperforming in key areas while being openly available on Hugging Face.

Where can I access DeepSeek-V4?

Available on Hugging Face under deepseek-ai/DeepSeek-V4-Pro, with a technical report detailing its architecture.

Why is DeepSeek-V4 significant for production?

Its efficiency boom positions it as a killer for RAG/agents with low latency and cost, advancing open-source capabilities.
