Tree-Structured Speculative Decoding: How Multi-Candidate Trees and Tree Attention Accelerate LLM Serving
Tree-Structured Speculative Decoding: How Multi-Candidate Trees and Tree Attention Accelerate LLM Serving Large language model inference is fundamentally constrained by memory bandwidth during the auto-regressive decoding phase. Because each token generation step requires loading billions of model parameters from high-bandwidth memory (HBM) to compute units for a single token, standard auto-regressive generation operates at low arithmetic intensity. Speculative decoding addresses this bottlene
