System Architecture Blueprint

Stage 01

Medusa Multi-Head Candidate Tree Proposal

  • Lightweight feed-forward decoding heads attached directly to base model layer
  • Simultaneous generation of candidate token branches across depth 1 to 4
  • Zero auxiliary draft model checkpoint VRAM consumption
Engineered Stack: CUDA 12.4 • Medusa Heads • C++20 • PyTorch 2.4
Stage 02

2D Tree-Attention Mask Compilation

  • Compiling candidate sequence paths into specialized 2D tree-attention masks
  • Parallel verification of all proposed branches in a single forward pass
  • Eliminating cross-model synchronization latency and kernel bubbles
Engineered Stack: TensorRT-LLM • Tree-Attention • Triton • OpenTelemetry
Stage 03

Exact Rejection Sampling & State Sync

  • Executing modified rejection sampling to guarantee 100% distribution fidelity
  • Instant resample from residual distribution on candidate rejection
  • Continuous logging of branch acceptance for self-tuning temperature loops
Engineered Stack: LangGraph • Redis • Pydantic v2 • Private VPC
