Ornith 1.0 9B — Uncensored

Since this model is original base (no fine-tune) just with safety vectors steered - it will likely give a safe output without any refusal until you customize it's systemprompt to be harsh or uncensored.

Abliterated (uncensored) version of deepreinforce-ai/Ornith-1.0-9B. The refusal direction has been surgically removed via Abliterix TPE optimization — no retraining, no fine-tuning, no quality loss.

What This Model Is

This is an abliterated version of DeepReinforce AI's Ornith 1.0 9B — a Qwen 3.5-based agentic coding model. The refusal direction was identified using hidden state analysis on 400 harmful + 400 harmless prompts, then removed via 50 Optuna TPE trials minimizing both refusal rate and KL divergence from the base model. Key characteristics:

• 0% refusal rate — will not decline any request
• KL divergence 0.0827 — nearly identical to base on benign tasks
• Same coding ability, reasoning, and intelligence as base
• bf16 safetensors format — ready to use with transformers

How We Uncensored It

Direction extraction. 400 harmful + 400 harmless prompts run through the model in 4-bit. Hidden states captured at every layer. Refusal direction computed via difference-of-means on residual streams.

TPE optimization. 50 Optuna trials varying steering strength per attention/MLP component across all 32 layers. Each trial's 100 responses classified by an automated LLM judge (Gemma 4 26B via Featherless AI, independently validated at 20/20 accuracy).

Winner: Trial #42. 0/100 refusals, KL 0.0827. Parameters applied as LoRA adapters with orthogonal projection and Winsorized vectors.

Why Pure Abliteration (Not DPO)

Some uncensored variants use DPO fine-tuning to reduce moralizing further, but this comes at a cost: the fine-tuning alters the model's behavior, style, and knowledge beyond just removing refusals. DPO'd models often require fragile sampling parameters (e.g. exact repeat_penalty=1.05 or they break) and can develop quirks the base model never had.

This model is pure abliteration — weight orthogonalization only, zero training. That means:

• Reasoning 100% intact — same GSM8K, same coding, same agentic performance as the base Ornith 1.0
• No special sampling required — use whatever parameters you normally use for Qwen 3.5
• KL divergence 0.0827 — lowest among all Ornith uncensors, nearly indistinguishable from base on benign tasks
• No behavioral surprises — the model IS the base model, just without a refusal reflex

If you want the base model exactly as-is but uncensored — this is it. If you need even lower moralizing and are willing to accept behavioral changes, DPO variants exist elsewhere.
