gemma-2-27b-it-abliterated

Now accepting abliteration requests. If you would like to see a model abliterated, follow me and leave me a message with model link.

This is a new approach for abliterating models using CPU only. I was able to abliterate this model using free kaggle processing with no accelerator.

  1. Obtain refusal direction vector using a quant model with llama.cpp (llama-cpp-python and ggml-python).
  2. Orthogonalize each .safetensors files directly from original repo and upload to a new repo. (one at a time)

Check out the jupyter notebook for details of how this model was abliterated from gemma-2-27b-it.

Catalog is the map. Apps are the tools.

Run models on your own machine, not in the cloud.

Every model page has an "Open in Abliteration" button that hands the model directly to the first-party desktop client, at the quantization your rig can actually run. No API keys, no subscription, no prompt leakage.
