gemma-3-12b-it-biprojected-abliterated

This model was derived from google/gemma-3-12b-it.

Projected abliteration has been applied in determining refusal direction, along with a second round of remove of projected contribution onto the harmless direction of layer targeted for intervention, which should further reduce model damage; no subsequent fine-tuning was applied to repair damage.
The net result is a model that refuses far less often than the original model, yet still retains awareness of safety and harms.

More details to follow.

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.
