What it does

Serve LLMs with structured generation and RadixAttention prefix caching

Best for

Agentic workflows with repeated prefixes (system prompts, tools) where 5× speedup via caching outweighs setup.

Inputs
  • · model checkpoint
  • · JSON/regex output constraints
  • · prompt template with prefix
  • · tool/function definitions
Outputs
  • · constrained generations (valid JSON/regex)
  • · parsed structured outputs
  • · tool call artifacts
Requires
  • · SGLang framework
  • · PyTorch
  • · HuggingFace transformers
  • · NVIDIA GPU
Preconditions

NVIDIA GPU with compute capability 8.0+; model compatible with SGLang

Failure modes
  • · Grammar constraint conflict with generation
  • · Prefix cache invalidation on dynamic prompts
  • · OOM on large batch sizes
  • · Tool definitions ambiguous
Trust signals
  • · 300K+ GPUs in production (xAI/AMD/NVIDIA/LinkedIn)
  • · RadixAttention prefix caching innovation
  • · Structured decoding correctness guarantees
