Qwen3.8-27B-heretic-ara-NVFP4-MTP

I wanted a high quality coding model that doesn't give me AI safety lectures. So I quantized a heretic model with big coding/conversational/Japanese (for my instruction app) datasets and copied layer config and MTP heads from unsloth/Qwen3.8-27B-NVFP4. llmcompressor wuantization script is included in model folder. Tested in Zoo code / chat / Japanese teacher app, seems to work well. I also finetuned drafter to the best of my ability to work with heretic / NVFP4 variant, getting 82.1% acceptance rate on first position in my tasks.

I have uploaded a separate DSpark MTP head in https://huggingface.co/catplusplus/Qwen3.8-27B-heretic-ara-DSpark. It provides significantly faster decode, but does not work with turboquant kv cache, so original MTP head uses less memory for given context length, both choices have pros and cons.

I run this model as follows (uses local scripts, just illustrating vLLM arguments)
