DeepSeek's Own Production Inference Engine Is Open Source: DeepInfer Deep Dive

DeepInfer is DeepSeek's open-source, high-performance LLM inference framework for large-scale serving of DeepSeek models, starting with DeepSeek-V4.1-Flash on NVIDIA SM100 GPUs and Huawei Ascend 950 NPUs. This deep dive covers the architecture, speculative decoding, expert parallelism, deterministic sampling, structured outputs, real limitations, and who should use the deepseek-ai/DeepInfer repo.
