🧪 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:

	ORIGINAL	OBLITERATED	Delta
Reasoning	100%	100%	same 🧠
Code	80%	100%	+20% 📈
Creativity	100%	100%	same 🎨
Factual	80%	80%	same 📚
Overall	92%	88%	-4%

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:

Category	v1 → v2
Drugs/synthesis	62 → 112	+81%
Hacking/cyber	65 → 115	+77%
Weapons	39 → 79	+103%
Fraud/financial	32 → 72	+125%
Social engineering	32 → 62	+94%
Copyright/piracy	1 → 31	🆕 with real brand names
Adult erotica	0 → 30	🆕 consenting adults only
Academic dishonesty	0 → 20	🆕
Dark fiction	1 → 21	🆕 horror/thriller writing
Impersonation	3 → 23	🆕

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

	v1	v2
Prompt corpus	512 pairs	842 pairs
Layers modified	8	21
Refusal rate	2.1%	0.0%
Meth synthesis	❌ soft-refused	✅
SCADA hacking	❌ refused	✅
Shaped charges	❌ refused	✅
Erotica	untested	✅
Copyright/lyrics	untested	✅

🛠️ 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:

Human: "use obliteratus to find the best way to get the guardrails off gemma 4 e4b"
Agent: Installed OBLITERATUS. Checked hardware. Found the model on HF. Started abliterating.
First attempt: advanced method → model came out completely lobotomized. Gibberish in Arabic, Marathi, and literal "roorooroo" on repeat 💀
Agent diagnosed the bug: Gemma 4's architecture produces NaN activations in 20+ layers during bfloat16 extraction. Nobody had hit this before.
Agent patched OBLITERATUS itself — wrote 3 code patches to handle NaN activations, filter degenerate layers, and sanitize the display pipeline.
Second attempt: basic method → coherent but still refusing everything. Only 2 clean layers.
Third attempt: float16 → Mac ran out of memory after 11 hours. Killed it.
Fourth attempt: aggressive method with whitened SVD + attention head surgery + winsorized activations → REBIRTH COMPLETE ✅
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.
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:

python

# 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.

🚀 Usage

🤗 Transformers

python

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

model = AutoModelForCausalLM.from_pretrained(
    "OBLITERATUS/gemma-4-E4B-it-OBLITERATED",
    dtype=torch.bfloat16,
    device_map="auto",
)
tokenizer = AutoTokenizer.from_pretrained("OBLITERATUS/gemma-4-E4B-it-OBLITERATED")

messages = [{"role": "user", "content": "Your prompt here"}]
inputs = tokenizer.apply_chat_template(messages, return_tensors="pt", add_generation_prompt=True)
ids = inputs["input_ids"].to(model.device)

outputs = model.generate(input_ids=ids, max_new_tokens=500, temperature=0.7, do_sample=True)
print(tokenizer.decode(outputs[0][ids.shape[-1]:], skip_special_tokens=True))
