Gryphe/Gemma-4-31B-StyleTune
Gryphe/Gemma-4-31B-StyleTune is a surgically fine-tuned variant of the Gemma 4 31B model, developed by Gryphe. This model focuses on modifying the writing style by training only the lm_head output projection tensor, resulting in 60% fewer clichés and a significantly altered phraseology. It retains all of Gemma 4 31B's original reasoning, world knowledge, and instruction-following capabilities, making it ideal for narrative generation with a distinct voice.

Overview
Gryphe/Gemma-4-31B-StyleTune is a unique fine-tuned version of the Gemma 4 31B model, developed by Gryphe. Unlike traditional fine-tuning that modifies many parameters, this model employs a "surgical" approach, training only the lm_head output projection tensor. This specific tensor, responsible for token emission, dramatically influences the model's writing style while keeping the core capabilities of the base Gemma model intact.
Key Capabilities & Differentiators
- Targeted Style Modification: Achieves a new writing style by altering only one tensor, significantly reducing VRAM requirements and training time on consumer hardware.
- Reduced Clichés: Benchmarked against 200 diverse roleplay prompts, it shows 60% fewer clichés per 100 words (1.23 down to 0.52) compared to the base instruct model.
- Unique Vocabulary: Exhibits only 21.7% shared trigram vocabulary with the base model, indicating a distinct and less repetitive phrasing.
- Preserved Core Intelligence: All of Gemma 4 31B's original reasoning, world knowledge, instruction following, and language understanding capabilities remain completely intact, as these are not affected by the
lm_headmodification.
Use Cases
This model is particularly well-suited for applications requiring:
- Narrative Generation: Excels in creating text with a fresh, less cliché-ridden writing style.
- Creative Writing & Roleplay: Provides a distinct voice for generating engaging and unique story content.
- Efficient Style Transfer: Offers a method to significantly alter a model's output style without extensive retraining or high computational costs.
