Qwythos-9B-v2-Heretic-GGUF

GGUF quantizations of WaveCut/Qwythos-9B-v2-Heretic — the Heretic-decensored version of empero-ai/Qwythos-9B-v2. Use these with llama.cpp, Ollama, LM Studio, KoboldCpp, or any other GGUF runtime.

Files

File	Format	~Bits/weight	Size	Recommended use
`Qwythos-9B-v2-Heretic.Q4_K_M.gguf`	K-quant (mixed)	4.5	~5.6 GB	Best 4-bit default — fits in ~6.5 GB VRAM, balanced quality/size
`Qwythos-9B-v2-Heretic.Q5_K_M.gguf`	K-quant (mixed)	5.5	~6.5 GB	Higher quality 5-bit, ~7.5 GB VRAM
`Qwythos-9B-v2-Heretic.Q6_K.gguf`	K-quant (mixed)	6.6	~7.4 GB	Very close to FP16, ~8.5 GB VRAM
`Qwythos-9B-v2-Heretic.Q8_0.gguf`	8-bit symmetric	8.5	~9.5 GB	Effectively lossless, ~10.5 GB VRAM

Quantization recipe

Step	Tool	Version
HF → F16 GGUF	`convert_hf_to_gguf.py`	llama.cpp `b9986` (commit `91c631b`), run with `--no-mtp`
Quantize	`llama-quantize`	llama.cpp `b9986` (prebuilt linux-x64)

Note on --no-mtp: the base Qwen3.5 model bundles a multi-token-prediction (MTP) head as block #32. Excluding it via --no-mtp produces a clean 32-block text GGUF that loads correctly in current llama.cpp builds. If you want speculative decoding with the MTP head, run convert_hf_to_gguf.py --mtp separately.

No imatrix (importance matrix) calibration was used — K-quants hold up well without one for this model size, and Q8_0 is format-defined and never benefits from it.

Architecture

Qwen3.5 hybrid — 32 blocks mixing attention and SSM (Mamba-style) layers. Supported in llama.cpp b9986 and later under the qwen35 architecture key.

Usage

# llama.cpp
llama-cli -m Qwythos-9B-v2-Heretic.Q4_K_M.gguf -p "Hello" --chat-template chat_template.jinja

# Ollama (create a Modelfile pointing to the .gguf)
ollama create qwythos-heretic -f Modelfile
ollama run qwythos-heretic
