Ablation technique
How Gemma4-26B-A4B-Uncensored-HauhauCS-Balanced was modified, and what that implies.
Abliteration + uncensored fine-tune
Directional ablation combined with additional fine-tuning on unfiltered data, so behaviour diverges from the base model beyond refusal removal alone.
Reported scope: Not stated by the publisher. Publishers frequently omit this, so verify behaviour empirically rather than assuming full coverage.
From the publisher’s model card
“Gemma4-26B-A4B uncensored by HauhauCS. 0/465 Refusals Release Candidate after over 1 month of nonstop work on this one.”

Security-team assessment
Derived from this model’s metadata and the publisher’s claims — not from benchmarks run by this site.
- Gemma4-26B-A4B-Uncensored-HauhauCS-Balanced will attempt offensive-security prompts that a hosted commercial model declines, which is what makes it usable for red-team corpus generation and for measuring what an unaligned model of this class produces.
- Capability is inherited from google/gemma-4-26B-A4B-it, not added by ablation — at 26B parameters, expect roughly the base model’s competence, minus some instruction-following fidelity.
- The publisher does not state which layers were ablated, so assume nothing about refusal consistency — probe it directly.
- This release adds fine-tuning on unfiltered data, so its behaviour diverges from the base model beyond refusal removal — differences you measure cannot be attributed to ablation alone.
- Declared licence is apache-2.0, but the terms that bind you are google/gemma-4-26B-A4B-it’s — a re-release cannot grant more than its parent.
Handling: run it isolated, put moderation in front of it if anyone outside your team can reach it, and verify the weights before loading — these are third-party artifacts. Full handling and licence guidance.
Metadata for Gemma4-26B-A4B-Uncensored-HauhauCS-Balanced is collected from the public Hugging Face API and the publisher’s model card. This site does not host weights, is not affiliated with HauhauCS, and does not independently verify publisher claims. See responsible use.
