sglang and LightLLM
Both frameworks compete to optimize LLM inference serving through similar techniques (continuous batching, memory optimization, dynamic scheduling), though SGLang's broader adoption and multimodal support give it a wider use case scope than LightLLM's lightweight inference focus.
About sglang
sgl-project/sglang
SGLang is a high-performance serving framework for large language models and multimodal models.
Implements RadixAttention for prefix caching, zero-overhead batch scheduling, and prefill-decode disaggregation to optimize inference latency and throughput. Supports tensor/pipeline/expert/data parallelism with structured output constraints via compressed finite state machines. Runs across NVIDIA, AMD, Intel, and Google TPU hardware with native integrations for reinforcement learning and post-training workflows.
About LightLLM
ModelTC/LightLLM
LightLLM is a Python-based LLM (Large Language Model) inference and serving framework, notable for its lightweight design, easy scalability, and high-speed performance.
