Trying to improve output speed with MLX models on LM Studio

Hello, I’ve been using LM Studio on my Macbook Pro M5 Max (128 GB) with mlx-community/qwen3.8-27b without issues, so I’m looking for ways to improve output speed (right now I’m getting 15-17 t/s) and found about speculative decoding. Looking around I found mlx-community/Qwen3.8-27B-MTP-8bit is a draft model for that, so I downloaded it, but when I try to enable speculative decoding, LM Studio says “No compatible draft models found for your current model selection”.

My LM Studio version is 0.4.25+1 and the MLX engine I’m using is LM Studio MLX (Apple M5) v1.11.0.

If anyone can suggest another draft model or any other way to improve output speed I’d really appreciate it. Thanks in advance.
