有人在 llama.cpp 上測試過 Gemma 4 31B IT 或 Qwen 3.5 27B 的推測解碼嗎?

A developer is asking the community about their experience with speculative decoding—a technique that speeds up AI model inference—using llama.cpp with two popular large language models: Gemma 4 31B IT and Qwen 3.5 27B. They're specifically interested in which smaller draft models work best as companions for faster generation and whether users actually saw real performance improvements. The question suggests some uncertainty about whether Qwen 3.5 even works well with llama.cpp's speculative decoding implementation.
