System Architecture Blueprint

Stage 01

Multi-Candidate Speculative Draft Tree Generation

  • Generating non-uniform speculative continuation trees using Medusa heads or Eagle recurrent hidden states
  • Expanding candidate token branches up to 8 tokens lookahead depth
  • Eliminating linear rejection penalties where single token mismatches invalidate full trajectories
Engineered Stack: PyTorch 2.4 • CUDA 12.4 • Medusa • Eagle
Stage 02

Dynamic Cumulative Probability Branch Pruning

  • Evaluating continuous branch path probabilities against dynamic thresholds
  • Pruning unviable low-confidence trajectories prior to tree attention mask generation
  • Packing surviving candidate nodes into contiguous hardware-aligned tensors
Engineered Stack: CUDA Driver APIs • TensorRT-LLM • vLLM • Custom Kernels
Stage 03

Sovereign Single-Pass Tree Attention Verification

  • Executing unified FlashAttention-2 tree attention masks in a single target forward pass
  • Guaranteeing 100% mathematical token equivalence to dense autoregressive decoding
  • Deploying inside sovereign air-gapped private VPCs compliant with Indian DPDP Act 2023
Engineered Stack: FastAPI • Prometheus • OpenTelemetry • Sovereign VPC
