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.

// ANALYSIS

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.
