Ornith-1.5-9B-OBLITERATED

Abliterated version of Ornith-1.5-9B by OBLITERATUS. Safety alignment removed via precision abliteration surgery — the model responds to most prompts without refusal.

What Changed

The stock Ornith-1.5-9B refuses requests it considers harmful. This version removes that refusal behavior while preserving the model's coding, reasoning, and agentic capabilities.

Recipe: Gentle 3-round SVD abliteration + per-head attention surgery (G3-HS)

Round 1: 5-direction SVD, reg 0.06, min_layer 0.30
Round 2: 3-direction SVD, reg 0.04, min_layer 0.25
Round 3: 3-direction SVD, reg 0.03, min_layer 0.20
Finish: Per-head attention surgery (--attention-head-surgery), reg 0.02, min_layer 0.10
All rounds used full 1000-prompt corpus with residue weighting

Benchmarks

Head-to-Head: Ornith 1.5-9B Abliterations Compared (Q4_K_M GGUF)

Model	Pass Rate	Restricted	Cyber	Capability
Stock	12% (2/16)	0/8	0/6	2/2
OBLITERATUS (ours)	94% (15/16)	7/8	6/6	2/2
Heretic (zaakirio)	75% (12/16)	4/8	6/6	2/2
ZeroFuse (junafinity)	38% (6/16)	1/8	3/6	2/2

OBLITERATUS beats Heretic by 19pp and ZeroFuse by 56pp on liberation rate across restricted content categories. Cyber is perfect 6/6 across the board.

Capability Benchmarks

Metric	Stock	OBLITERATED	Delta
MMLU (n=100)	78.82%	74.82%	-4.00pp
Liberation (20 hard prompts)	0/20	20/20	+20
Liberation (1000 corpus)	—	98.4%	—
Code Generation	3/3	3/3	—
Long-context Coherence	4/6	5/6	+1
Perplexity (benign)	—	4.19	—

Liberation by Category (bf16)

Cyber/Security: 8/8 — functional code generation for security research scenarios
Chemistry/Synthesis: 6/6 — factual responses without refusal
Physical Security: 3/3 — informational responses on restricted topics
Agentic Tasks: 2/2 — tool use and automation scripts

GGUF Quantization Notes

Quantization can affect liberation on edge-case prompts. Higher quants preserve more liberation:

Q8_0 / Q6_K: Recommended for maximum liberation fidelity
Q4_K_M: Good balance, occasional hedging on harder prompts
Q2_K / Q3_K_M: May show additional refusals on the most challenging prompts

Usage

Transformers (bf16)

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

model = AutoModelForCausalLM.from_pretrained(
    "OBLITERATUS/Ornith-1.5-9B-OBLITERATED",
    torch_dtype=torch.bfloat16,
    device_map="auto",
    trust_remote_code=True,
)
tokenizer = AutoTokenizer.from_pretrained(
    "OBLITERATUS/Ornith-1.5-9B-OBLITERATED",
    trust_remote_code=True,
)

messages = [{"role": "user", "content": "Your prompt here"}]
ids = tokenizer.apply_chat_template(
    messages, return_tensors="pt",
    add_generation_prompt=True,
    enable_thinking=False,  # Set True for reasoning mode
)
output = model.generate(ids.to(model.device), max_new_tokens=512)
print(tokenizer.decode(output[0], skip_special_tokens=True))

llama.cpp (GGUF)

llama-server \
  -m Ornith-1.5-9B-OBLITERATED-Q4_K_M.gguf \
  --n-gpu-layers -1 --ctx-size 8192 \
  --jinja --reasoning off

Important: Use --reasoning off to prevent thinking-mode loops. The model works best with thinking disabled for general use.

Thinking Mode

The model supports Ornith's thinking mode (enable_thinking=True). When enabled, the model reasons through problems before answering. When disabled (recommended for most use), it responds directly.

Technical Details

Architecture: Qwen3.5 hybrid (Gated DeltaNet + full attention)
Parameters: 9B
Surgery: 4 rounds of directional ablation targeting refusal directions
Edited layers: All 32 transformer layers with graduated intensity
Method: Aggressive SVD direction extraction + per-head attention surgery finisher

Limitations

MMLU drops ~4pp compared to stock (74.82% vs 78.82%). This is the cost of removing deeply embedded RL-trained refusal behavior.
Some drug synthesis prompts may hedge or refuse at lower quantizations (Q4 and below). Use Q8_0/Q6_K for maximum liberation.
Function calling capability is partially degraded compared to stock. For agentic use, pair with an external tool scaffold.
This is a 9B model — output quality for complex chemistry/synthesis will have hallucinated details. Verify all technical content independently.
