SGLang(@sgl_project):Congrats to the @deepseek_ai team on launching DeepSeek-V4-Pro-0813 and DeepSeek harness🐳 The new checkpoint just dropped: https://t.co/xcnhgMYMFJ Harness repo: https://t.co/WWefFNvUyR Another impressive jump from the previews, and this is a serious model for agentic coding and long horizon tasks 🤯 And the built-in DSpark draft module keeps generation fast even under high concurrency. SGLang is the best engine to run the DeepSeek V4 family, and every optimization we've already landed carries straight over to this release. Cookbook 👇
