What problem does it solve?
This Skill addresses the significant latency and throughput bottlenecks in serving Large Language Models (LLMs), especially for agentic workflows and structured generation tasks, by dramatically speeding up inference.
Core Features & Use Cases
- Fast Structured Generation: Enables 5x faster inference for LLMs, particularly for tasks requiring JSON, regex, or grammar-constrained outputs, and agentic workflows with tool calls.
- Automatic Prefix Caching: RadixAttention technology automatically reuses KV cache for common prefixes, leading to substantial speedups in multi-turn conversations, few-shot prompting, and agentic loops without manual configuration.
- Use Case: Building an AI agent that repeatedly uses the same system prompt and tool definitions to answer user queries. SGLang will cache these common parts, making each subsequent query much faster.
Quick Start
Use the sglang skill to launch a server for the Llama 3-8B model on port 30000 with automatic prefix caching enabled.
