SGLang powers major AI inference despite vLLM's higher GitHub stars · 1 source tracked

The choice of inference engine for self-hosting large language models is critical for operational efficiency and cost, with vLLM, SGLang, and TensorRT-LLM being the primary contenders. Despite vLLM's higher GitHub star count, SGLang is powering significant deployments like xAI's Grok and Microsoft Azure's DeepSeek R1, highlighting a divergence between community popularity and production use. This decision impacts GPU utilization, latency, hardware flexibility, and engineering effort, especially with the rise of agentic workloads that involve long, repetitive prefixes and high call volumes.
