DeepSeek has open-sourced DeepInfer, an inference engine designed to serve its production models. This framework, built upon vLLM with contributions from other projects like SGLang and TensorRT-LLM, supports DeepSeek-V4.1-Flash and targets NVIDIA SM100 GPUs and Huawei Ascend 950 NPUs. While DeepInfer includes advanced features like speculative decoding and deterministic sampling, it is primarily an offline inference tool, lacking key components for production serving such as KV cache management and load balancing.
