VerifiedThe open-source version of DeepInfer is not a complete production system and does not include parts coupled with internal infrastructure, such as KV buffer management, cross-machine prefill-decode disaggregation, and load balancing across replicas.80% similarUnverifiedDeepSeek officially stated clearly that the DeepInfo framework does not include advanced features such as the KVCash system, Lütiancong and decoupled-decoding multiple replicas, and load balancing.79% similarUnverifiedWhat DeepInfer open-sourced is the offline inference core; the complete online service chain still requires filling in the caching layer and load balancing yourself.76% similarUnverifiedDeepInfer is released free and open, allowing research and commercial use, but it is not a complete production system; it lacks caching and load-balancing infrastructure, so its economic benefits cannot be directly replicated.76% similarUnverifiedDeepInfer is currently an offline engine that does not provide out-of-the-box online service capability, and is closer to an inference kernel and scheduling reference implementation than a finished product that can directly replace vLLM production deployments.73% similar
