DFlash doubles Qwen 3.5 speeds on Apple Silicon
DFlash is an open-source speculative decoding framework for Apple's MLX that uses parallel block prediction and custom Metal kernels to accelerate local inference. By verifying multiple draft tokens in a single pass, it doubles Qwen 3.5 speeds on M5 Max without compromising output accuracy.
Speculative decoding is the clear path forward for running large local models on Mac architectures. DFlash's optimization for Qwen 3.5 demonstrates that fine-tuned MLX integration yields multi-fold performance gains without compromising quality. Its lossless output ensures speed gains don't sacrifice accuracy, while custom Metal kernels for "innovation tape" rollback and OpenAI-compatible server support facilitate immediate adoption.
