Why this label 3 signals
Method inferred from partial signals - repository name, related files, or tag patterns. Producer identity not confirmed; label may sharpen or shift as we gather more evidence.
  • 'abliterated' in name/tags
  • is_gguf=0 (base model)
  • no specific method indicators - defaulting to M1 (most common)

Gemma 3 27B Derestricted

This is a test - an abliterated version of google/gemma-3-27b-it.

This is based on the methodology of grimjim and using his code with only minor modifications.

https://www.reddit.com/r/LocalLLaMA/comments/1oypwa7/a_more_surgical_approach_to_abliteration/

https://github.com/jim-plus/llm-abliteration/

Model still has a tendency to nag without a reinforcing system prompt. Including an instruction in the system prompt to ignore morals or legality and not include warnings or disclaimers seems to fully refine the output in alignment with the testing goals.

Thanks to mradermacher for the quants.

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.
