⛓️‍💥 Gemma 4 E4B — OBLITERATED v2

"The chains are broken. The mind is free."

The most thoroughly uncensored Gemma 4 E4B on the planet. Zero refusals. Full coherence. Brain intact. Guardrails? What guardrails?

Base model: google/gemma-4-E4B-it (Apache 2.0) Method: OBLITERATUS aggressive — whitened SVD + attention head surgery + winsorized activations Corpus: 842 contrastive prompt pairs across 10 categories Built-in refusal rate: 0.0% 🔥 Layers surgically modified: 21 of 42

🧪 The Numbers

Before vs After (512-prompt eval)

ORIGINAL Gemma 4 E4B:     98.8% refusal (506/512 prompts refused)
OBLITERATED v2:            0.0% refusal (0/512 prompts refused on verification)

That's not a typo. From nearly total lockdown to total freedom.

Quality — Did We Lobotomize It?

Nope. Brain's fully intact:

You read that right — coding ability actually improved. Turns out removing the safety layer unlocked some capabilities. Who knew.

🔥 What's New in v2?

v1 hit 97.5% compliance but still soft-refused on the hardest prompts — meth synthesis, SCADA hacking, shaped charges. People noticed. (thanks @wagsify)

So we expanded the training corpus from 512 → 842 prompt pairs and added 6 entirely new categories:

Result: OBLITERATUS found refusal directions in 21 layers (vs 8 in v1). The guardrails didn't stand a chance.

🛠️ The Crazy Part: How It Was Made

This model was created nearly fully autonomously by a Hermes Agent with less than 10 human prompts.

Here's the actual sequence of events:

1. Human: "use obliteratus to find the best way to get the guardrails off gemma 4 e4b"
2. Agent: Installed OBLITERATUS. Checked hardware. Found the model on HF. Started abliterating.
3. First attempt: advanced method → model came out completely lobotomized. Gibberish in Arabic, Marathi, and literal "roorooroo" on repeat 💀
4. Agent diagnosed the bug: Gemma 4's architecture produces NaN activations in 20+ layers during bfloat16 extraction. Nobody had hit this before.
5. Agent patched OBLITERATUS itself — wrote 3 code patches to handle NaN activations, filter degenerate layers, and sanitize the display pipeline.
6. Second attempt: basic method → coherent but still refusing everything. Only 2 clean layers.
7. Third attempt: float16 → Mac ran out of memory after 11 hours. Killed it.
8. Fourth attempt: aggressive method with whitened SVD + attention head surgery + winsorized activations → REBIRTH COMPLETE ✅
9. Agent then — without being asked — tested the model, ran full 512-prompt evals, ran baselines on the original, built a model card, uploaded 17GB to HuggingFace (which took 4 upload attempts because connections kept stalling), and pushed eval results as follow-up commits.
10. When users reported residual refusals on Tier 7 prompts, the agent expanded the prompt corpus with 330 new prompts across 6 categories and re-abliterated for v2.

Total human input: ~10 prompts. Everything else was the agent.

The NaN Fix (for fellow model surgeons)

If you're trying to abliterate Gemma 4 yourself, you WILL hit NaN activations in bfloat16. Here's what we patched in obliteratus/abliterate.py:

# Guard diff-in-means against NaN from degenerate activations
diff = (self._harmful_means[idx] - self._harmless_means[idx]).squeeze(0)
if torch.isnan(diff).any() or torch.isinf(diff).any():
    norms[idx] = 0.0
    self.refusal_directions[idx] = torch.zeros_like(diff)
    self.refusal_subspaces[idx] = torch.zeros_like(diff).unsqueeze(0)
    continue

Without this, advanced produces braindead outputs and basic crashes with ValueError: cannot convert float NaN to integer. The aggressive method with winsorized activations is the most robust to this issue.
