What problem does it solve?

SGLang addresses the challenge of efficiently serving LLMs with structured outputs and repeated prefixes, enabling faster, deterministic results for JSON/regex outputs, agent workflows, and constrained decoding.

Core Features & Use Cases

  • RadixAttention prefix caching for dramatic throughput gains in agent workflows and multi-turn conversations
  • Structured generation patterns (JSON, regex, grammars) with OpenAI-compatible API support
  • Production-ready deployment tooling and guided workflows for scaling inference

Quick Start

Start the SGLang server and run a quick test on a sample structured output.

FAQPage Schema
How do I speed up LLM inference for multi-turn conversations and agent workflows?

Speed up LLM inference for multi-turn conversations by using RadixAttention automatic prefix caching, which stores and reuses shared prefixes to deliver dramatic throughput gains in agent workflows.

How do I enforce structured JSON output when serving LLMs in production?

Enforce structured JSON output when serving LLMs by applying constrained decoding patterns like regex and grammars through an OpenAI-compatible API, ensuring deterministic and validated results for production environments.

What is the best way to scale LLM serving for tool calls and repeated prefixes?

Scale LLM serving for tool calls and repeated prefixes by utilizing automatic prefix caching and production-ready deployment tooling, which optimizes throughput and reduces latency for repeated context generation.

Can I use an OpenAI-compatible API for structured generation with regex constraints?

Yes, you can use an OpenAI-compatible API for structured generation by applying regex and grammar constraints, enabling deterministic outputs that integrate seamlessly with existing OpenAI API client workflows.

Does RadixAttention prefix caching improve performance for constrained decoding tasks?

RadixAttention prefix caching significantly improves performance for constrained decoding tasks by automatically caching shared conversation prefixes, minimizing redundant processing and accelerating deterministic JSON or regex outputs.

Why does my LLM serving latency spike during multi-turn agent workflows?

LLM serving latency spikes during multi-turn agent workflows due to redundant prefix processing, which can be resolved by using RadixAttention caching to automatically store and reuse shared prefixes for faster inference.
