AccBalanced · x · 2026-10-26
The vLLM team published a blog post detailing how it matched DeepSeek's own DeepInfer engine on DeepSeek-V4.1-Flash, with results independently verified in SemiAnalysis' AgentX benchmark.
- vLLM matches DeepInfer's performance across decode batch sizes 8 to 256 under DeepSeek's decode configuration
- It does so at DEP32 versus DeepInfer's EP64DP64
- DeepInfer was originally built on vLLM; by integrating DeepSeek's open-source kernels and heavily optimizing prefill and decode, vLLM now matches DeepInfer's performance curves
