SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Slow, unstructured prompt processing and inefficient KV cache usage in LLM serving leads to high latency and limited throughput; RadixAttention addresses this by caching and reusing common prefixes across requests.

Core Features & Use Cases

  • RadixAttention automatic prefix caching for multi-turn conversations, few-shot prompts, and tool-using agents.
  • Structured generation support (JSON, regex, grammars) with OpenAI-compatible API.
  • Easy deployment guides and OpenAI API compatibility for production-grade serving.

Quick Start

Install SGLang, start the server with your model path, and connect an OpenAI-compatible client to begin serving structured prompts at scale.

FAQPage Schema
How do I reduce LLM serving latency for repeating multi-turn conversations?

Reduce LLM serving latency by using RadixAttention to cache and reuse common prompt prefixes across multi-turn conversations. This mechanism optimizes KV cache usage, bypassing redundant processing for repeating inputs to improve throughput.

How do I enforce structured JSON or regex outputs from an OpenAI-compatible API?

Enforce structured JSON or regex outputs from an OpenAI-compatible API by deploying a server that supports grammar-based generation. This ensures model responses strictly match your defined JSON schemas or regular expressions for production reliability.

Can I use prefix caching for few-shot prompts and agent workflows?

Yes, you can use prefix caching for few-shot prompts and agent workflows. RadixAttention automatically identifies and reuses shared prefixes across these complex requests, accelerating structured generation at scale without manual cache management.

What is the best way to accelerate structured generation at scale for production?

The best way to accelerate structured generation at scale is implementing an OpenAI-compatible API surface with RadixAttention. This caches common prefixes and supports JSON or grammar-based outputs, enabling efficient production deployments.

Why does my LLM serving throughput drop with unstructured prompt processing?

Throughput drops because unstructured prompt processing leads to inefficient KV cache usage and high latency. RadixAttention solves this by caching and reusing common prefixes across requests, optimizing processing for structured outputs.
