New LoRA Bypasses Krea 2 Safety Filter by Only Targeting Refusal Vectors, Avoiding Image Distortion
English summary
A new LoRA file, 'Krea2 Filter Bypass Fedor,' has been publicly released on Civitai that effectively disables the safety filter in Krea 2 diffusion transformer by overwriting only the two refusal-associated control knobs (9 and 10) while leaving all others at zero. Unlike earlier bypasses that modified multiple knobs and caused style warping or plasticized faces, this approach mathematically guarantees no style or anatomy drift because zeroed knobs cannot be moved by strength adjustments. The LoRA stacks cleanly with realism, character, and style LoRAs without interference, letting the base model's own quality shine through. A recommended strength of 3–5 defeats most refusals, and the author suggests switching to FilterBypass3 for any remaining knob-11-based refusals. The design was derived from a community vector analysis by u/piero_deckard, identifying the exact roles of each knob.
Chinese summary
一个名为 'Krea2 Filter Bypass Fedor' 的新 LoRA 文件已在 Civitai 上公开发布，它通过仅覆盖两个与拒绝控制相关的旋钮（9 和 10）并将其他所有旋钮置零，有效禁用了 Krea 2 扩散变换器中的安全过滤器。与之前会干扰多个旋钮并导致风格扭曲或塑料化面孔的绕过方法不同，该方法从数学上保证了无风格或解剖学偏移，因为置零的旋钮无法被强度调整所移动。该 LoRA 可与写实、角色和风格 LoRA 干净地叠加，无相互干扰，让基础模型自身质量得以展现。推荐强度 3–5 即可绕过大多数拒绝，作者建议对仍基于旋钮 11 的拒绝切换到 FilterBypass3。该设计源自社区用户 u/piero_deckard 的向量分析，该分析确定了每个旋钮的确切作用。
Key points
New LoRA bypasses Krea 2 safety filter by targeting only refusal knobs 9 and 10, setting others to zero.
新 LoRA 通过仅修改拒绝旋钮 9 和 10 并将其他置零来绕过 Krea 2 安全过滤器。
Zeroing out knobs 1–8, 11, and 12 prevents any style, anatomy, or expression warping even at high strength.
将旋钮 1–8、11 和 12 置零可防止高强度下任何风格、解剖或表情扭曲。
The LoRA stacks cleanly with other LoRAs without interference, unlike earlier bypasses that caused tug-of-war effects.
该 LoRA 可与其他 LoRA 干净叠加，无干扰，而早期绕过方法会导致拉锯效应。
