🚨⚠️ I HAVE REACHED HUGGING FACE'S FREE STORAGE LIMIT ⚠️🚨
I can no longer upload new models unless I can cover the cost of additional storage.70+ free models as an independent contributor and this work is unpaid.Without your support, no more new models can be uploaded.
Every contribution goes directly toward Hugging Face storage fees to keep models free for everyone.
85% fewer refusals (15/100 Uncensored vs 99/100 Original) while preserving model quality (0.0100 KL divergence).❤️ Support My Work
Creating these models takes significant time, work and compute. If you find them useful consider supporting me:
image/png Your help will motivate me and would go into further improving my workflow and coverings fees for storage, compute and may even help uncensoring bigger model with rental Cloud GPUs.

Metric This model Original model (G4-MeroMero-31B ) KL divergence 0.0100 0 (by definition) Refusals ✅ 15/100 ❌ 99/100
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.

Gemma4 31B

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.

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.
