# Jun Song: Qwen3.8-27B Speculative Decoding (DFlash 2)

## Inhalt
Jun Song: "Qwen3.8-27b hitting 70 tok/s on a single MacBook. That is faster than Fable or Sol. Speculative decoding is easily the biggest breakthrough in local AI this year. Next up, the real innovation is going to happen in prefill and weight compression."
