SGLang: A Structured Generation Language for Efficient Execution of Complex Language Model Programs

Practical Solutions for Efficient Execution of Complex Language Model Programs

Introducing SGLang: A Game-Changing Language for LM Programs

Recent advancements in LLM capabilities have made them more versatile, enabling them to perform a wider range of activities autonomously. However, existing methods for expressing and running LM programs could be more efficient. This has led to two main obstacles in effective LM program utilization: the non-deterministic nature of LLMs and wastage of memory and computational resources due to redundant calculations.

A group of researchers from Stanford University, UC Berkeley, Shanghai Jiao Tong University, and Texas A&M University have introduced SGLang, a Structured Generation Language for LLMs, to address these challenges. SGLang aims to speed up the execution of LM programs and make programming easier, offering primitives for controlling parallelism and generation. It works seamlessly with Python’s libraries and control flow, allowing users to build sophisticated prompting processes using natural syntax.

The team has also presented a compiler and an interpreter for SGLang, ensuring efficient synchronization and intra-program parallelism. To further enhance the runtime, the researchers suggest several new optimizations, including RadixAttention and a compressed finite state machine. The performance evaluation on NVIDIA GPUs has shown that SGLang outperforms existing systems by up to 6.4 across various workloads, models, and hardware configurations.

Despite the progress, there are areas for further research and improvement, such as adding support for more output modalities, enhancing RadixAttention, and implementing advanced static optimizations in the SGLang compiler.
