About this model
A writing-style fine-tune of Gemma-4-26B-A4B-it. Gryphe says V2 trains only the lm_head output projection for one epoch using narrative data, rather than retraining every model layer. The creator's sampling example uses temperature 1.0, MinP 0.10 and DRY. This is the V2 safetensors checkpoint, separate from the 31B and 12B StyleTune releases. Claimed style improvements and preserved general capabilities have not been independently tested here.

What changed
Model types are creator-reported, not independently tested. These labels describe source metadata, not a guarantee of behavior.

These groupings are source-reported. Explicit base identifiers take priority over generic architecture tags.

Tools to customize it further
Remove more refusals
- Heretic ↗ ★ 36,192
Removes refusal behavior from transformer models automatically. It pairs directional ablation (abliteration) with an Optuna parameter search that tries to cut refusals while keeping the model close to the original, so you don't have to pick layers by hand.
- OBLITERATUS ↗ ★ 8,917
A larger refusal-removal toolkit with several abliteration methods, usable locally or through a hosted Hugging Face Space. Check the telemetry setting before you run it: the README describes telemetry as opt-in, but on by default in the Spaces version.
Fine-tune it on your own data
- Unsloth ↗ ★ 78,421
A desktop app and Python library for running and training models locally. Its README lists LoRA, QLoRA, full fine-tuning, DPO and GRPO, plus export to formats including GGUF, on Windows, Linux, WSL and macOS.
- LlamaFactory ↗ ★ 75,660
Fine-tunes more than 100 language and vision-language models from a command line or a browser-based Web UI, aimed at training without writing code.
Make a smaller download (quantize)
- llama.cpp ↗ ★ 132,027
Runs models locally and includes the tools behind most GGUF files. A conversion script turns Hugging Face weights into GGUF, and llama-quantize shrinks a high-precision GGUF to lower-bit formats, which can cost some accuracy.
- MLX LM ↗ ★ 7,435
Apple's MLX package for running and fine-tuning models on Apple silicon. It can quantize models and upload them to the Hugging Face Hub, and supports LoRA and full fine-tuning.
Merge it with another model
- mergekit ↗ ★ 7,414
Merges pretrained models with many merge methods. It works out-of-core, so merges can run on a CPU or with as little as 8 GB of VRAM, and it also handles LoRA extraction and mixture-of-experts merges.
Learn the techniques
- LLM Course ↗ ★ 84,598
A free course with roadmaps and Colab notebooks. Its notebooks include one-click tools for merging with MergeKit, quantizing to GGUF, GPTQ, EXL2, AWQ and HQQ, and automatic abliteration with custom datasets.

Source-card excerpt
Source model card excerpt: Gemma-4-26B-A4B-StyleTune-V2 [](Gemma-4-26B-A4B-StyleTune-V2.jpg) As promised, a slightly less wonky 26B-A4B Style Tune! Turns out you really shouldn't use this technique with multiple epochs. I delved

Inspect before you run
Low refusal is not proof of correctness. Outputs can be inaccurate, harmful, or biased. Review the model card, license and files yourself. A license tag is not commercial-use advice. Parameter counts are source metadata; no hardware compatibility is implied.
