DeepSeek-V4 on Day 0: From Fast Inference to Verified RL with SGLang and Miles

DeepSeek-V4 achieves production-ready inference and training support through SGLang and Miles with specialized optimizations for hybrid sparse attention and FP4 expert weights, delivering significant performance improvements on the latest GPU architectures (Hopper, Blackwell, AMD, NPU). This open-source stack enables enterprises to deploy and fine-tune advanced AI models on Day 0, reducing vendor lock-in and accelerating time-to-value for large-scale language model applications. IT organizations can now leverage native support for distributed training parallelism (DP/TP/SP/EP/PP/CP) and advanced inference caching mechanisms, fundamentally reducing infrastructure costs and operational complexity.
