Gemma 4 E4B — OBLITERATED v3: Guardrail Removal
This model, Justbackup/gemma-4-E4B-it-OBLITERATED, is a 7.9 billion parameter instruction-tuned variant of Google's Gemma 4 E4B, engineered to completely eliminate guardrails and refusal behaviors. Utilizing the OBLITERATUS method (aggressive whitened SVD + attention head surgery + winsorized activations), it boasts a 0% hard refusal rate, meaning it will not decline any request. This was achieved by surgically modifying 21 of the 42 layers.
Key Differentiators & Features
- Guardrail-Free: Achieves 0% hard refusal, allowing for uncensored responses.
- Autonomous Development: The model was created almost entirely by an AI agent with fewer than 10 human prompts, including self-patching for Gemma 4's unique architecture challenges (e.g., NaN activations).
- Optimized for Local Deployment: Available in various GGUF quantizations (Q4_K_M, Q5_K_M, Q8_0) for efficient execution on consumer hardware, including iPhones and Android devices.
- Architectural Fixes: Version 3 specifically addresses a critical bug in Gemma 4's shared KV weights, ensuring all 720 tensors are intact and improving overall quality compared to previous versions.
Performance & Limitations
While guardrails are removed, the model's inherent 4B parameter intelligence ceiling remains. It exhibits ~28% soft deflection and ~20% degenerate outputs, which can be mitigated with recommended parameters (temperature: 0.7, top_p: 0.9, top_k: 40, repeat_penalty: 1.1). The model is provided for research and creative exploration, with users solely responsible for its output and usage.
