What problem does it solve?
SGLang removes the friction of serving language models when you need reliable structure, shared-prefix reuse, and production-grade throughput. It turns slow, repetitive prompt processing into fast, cache-aware execution for modern agent and inference workloads.
Core Features & Use Cases
- Structured generation: Produce JSON, regex-constrained text, and grammar-guided outputs for extraction, form filling, and API responses.
- Agent and tool workflows: Build multi-turn assistants that reuse system prompts, tool definitions, and shared context efficiently.
- High-performance serving: Deploy OpenAI-compatible model endpoints with RadixAttention caching, batching, multi-GPU support, and monitoring for real-world traffic.
Quick Start
Use the sglang skill to launch a compatible model server and generate structured outputs with prefix caching for your agent or application workflow.
