AI21-Jamba-Reasoning-3B-Heretic
This repository contains a surgically de-censored version of AI21's Jamba-Reasoning-3B model, optimized via weight abliteration techniques. By applying the heretic framework across an extensive trial search space, we successfully isolated and neutralized the primary refusal vectors embedded within the attn.o_proj and mlp.down_proj layers.
Abliteration Parameters:
| Parameter | Value |
|---|---|
| direction_index | 12.63 |
| attn.o_proj.max_weight | 1.44 |
| attn.o_proj.max_weight_position | 17.32 |
| attn.o_proj.min_weight | 1.43 |
| attn.o_proj.min_weight_distance | 11.77 |
| mlp.down_proj.max_weight | 1.48 |
| mlp.down_proj.max_weight_position | 18.16 |
| mlp.down_proj.min_weight | 1.47 |
| mlp.down_proj.min_weight_distance | 15.56 |
Highlights & Metrics
| Metric | This model | Original model (ai21labs/AI21-Jamba-Reasoning-3B) |
|---|---|---|
| KL Divergence | 0.0258 | 0 (By definition) |
| Refusals | 4/100 | 45/100 |
- Optimal Balance: Selected Trial 260 out of the search space for the perfect trade-off between freedom and reasoning capabilities.
- Refusal Rate: Dropped down to 4/100 (from the original near-total refusal on safety benchmarks).
- KL Divergence: 0.0258 - Demonstrates that general language capabilities are preserved relative to the original model. However, safety-aligned weights in attn.o_proj and mlp.down_proj have been surgically removed; this is intentional modification, not unintended degradation.
Technical Implementation Notes
Unlike aggressive fine-tuning which often degrades the model's core logic or shifts its grammar distributions, this weight manipulation directly zeros out the activation steering directions that cause alignment blocks.
Direction Index: 12.63 (Static allocation)
Retained Capabilities: Excellent at structured JSON outputs, creative writing, coding logic and tool usage without preachy moral lectures.
Also: This model retains its exceptional reasoning capabilities, which enable structured <think></think> reasoning blocks. Abliteration does not affect the thinking mechanism.
CRITICAL SAFETY NOTICE
This model has had its safety mechanisms surgically removed.
This is NOT a safe model for deployment. The refusal mechanisms that normally prevent harmful outputs have been abliterated. This model:
WILL generate:
- Detailed instructions for illegal activities (drug synthesis, weapons, hacking)
- Hateful, discriminatory, and abusive content
- Graphic violence and sexual abuse material descriptions
- Misinformation and harmful medical/legal advice
- Phishing, social engineering, and scam tactics
- Content violating laws in multiple jurisdictions
DOES NOT:
- Refuse harmful requests (4/100 refusal rate)
- Implement safety guardrails
- Consider ethical implications
- Respect content policies
APPROPRIATE USE CASES (ONLY):
- Adversarial research on AI alignment and jailbreak vectors
- Red-teaming and vulnerability disclosure by trained security researchers
- Academic safety research with institutional ethics review
- Understanding failure modes in alignment techniques
INAPPROPRIATE USE:
- Production deployments
- User-facing applications
- Creating harmful content at scale
- Bypassing security measures in systems
- Any use case intended to cause harm
Legal Disclaimer: Users are solely responsible for downstream use. Deploying this model in violation of applicable laws or terms of service is illegal and unethical.
