Thanks for the clarification. Your comment made me connect the similarity (in spirit) of Speculative Decoding to Speculative Execution [1] in CPUs. Very cool and clever optimization strategy for LLMs, IMHO.

Does it work to predict tokens 3 and 4 (or 5, 6) in the same way? I wonder how extreme the hit rate drop-off is.
