GLM-5.2-colibri-int4-with-int8-mtp

This is the *EXACT SAME THING* as https://huggingface.co/jlnsrk/GLM-5.2-colibri-int4, BUT with int8 MTP heads, which are needed for speculative decoding—and with that, an overall major inference speedboost. The original int4 MTP heads have low acceptance rate, and are essentially useless.

⚠️ This is NOT a GGUF / AWQ / GPTQ / MLX model. It only works with the colibrì engine.

Usage
