Speculative Decoding in vLLM on AMD GPUs

Exploring Speculative Decoding in vLLM on AMD GPUs TL;DR: Speculative decoding allows vLLM to verify multiple drafted tokens in a single target-model pass. In our experiments, its effect on output-token throughput varied across drafting methods and proposal lengths, and also depended on the model family, draft checkpoint, workload, and acceptance behavior.
