Dustin: Draft-Augmented Sparse Verification for Efficient Long-Context Generation with Speculative Decoding
Dustin reports 27.85x self-attention and 9.17x end-to-end speedups at 32k length on Qwen2.5-72B using draft-augmented sparse verification with negligible accuracy loss on PG-19 and LongBench.
