arXiv:2607.08642v1 Announce Type: new Abstract: Speculative decoding accelerates LLM inference by drafting several tokens and verifying them in parallel. Block-diffusion drafters such as DFlash produce a draft block in one pass but model only per-position marginals; best-first tree methods such as DDTree expand candidate trees from those marginals. The released Domino drafter adds a GRU-based causal correction that makes each draft token's distribution path-dependent, a structure DDTree's factorized formulation cannot represent. We introduce DominoTree, a training-free best-first draft tree sc
The continuous drive for more efficient and faster Large Language Model inference necessitates ongoing research into advanced decoding techniques like speculative decoding, especially as LLM scale increases.
Improved speculative decoding techniques like DominoTree can significantly reduce the computational cost and latency of LLMs, making their deployment more feasible and widespread across various applications.
The introduction of DominoTree offers a training-free method to leverage the path-dependent distributions in techniques like Domino, potentially leading to substantial accelerations in LLM inference without requiring complex retraining.
