GGUF quantizations of llmfan46/G4-MeroMero-31B-uncensored-heretic.

This is a decensored version of zerofata/G4-MeroMero-31B, made using Heretic v1.2.0 with the Arbitrary-Rank Ablation (ARA) method

Abliteration parameters

Targeted components

• attn.o_proj

Performance

Lower refusals indicate fewer content restrictions, while lower KL divergence indicates more closeness to the original model's baseline. Higher refusals cause more rejections, objections, pushbacks, lecturing, censorship, softening and deflections.

A Vision Projector File is Required for vision/multimodal capabilities. Use alongside any quantization above.

Usage

Works with llama.cpp, LM Studio, Ollama, and other GGUF-compatible tools.

Mero Mero

Gemma4 31B

01 Overview

A finetune of Gemma 4 31B designed for creative tasks.

Another difficult to work with but extremely good model from Google.

This model has a slightly better swipe diversity and a less flowery / verbose writing style. Reasoning tends to average out being a bit longer than the original however. Intelligence appears to be on par with the original.

Supports both thinking and non thinking.

04 Creation Process

Creation Process: SFT > Merge

SFT on approx 49 million tokens.

Despite using 49 million tokens, this dataset is fairly modest in size. Trainable is somewhere in the rough ballpark of 10-15 million. All of the datasets were trained on the last turn only, to faithfully mirror the Gemma 4 chat template

The approach was very similar to the 26B A4B MeroMero. I trained the model aggressively for 2 epochs on my data and after testing various checkpoints, settled for the one at 1 epoch, which had the style and the least signs of overfitting.

I merged this checkpoint back into the original instruct which cleaned up any remaining overfitting while still retaining the changes of the finetune.

Trained using Axolotl.
