| Operon Prompt Injection Detector -- Interactive Gradio Demo | |
| =========================================================== | |
| Two-layer defense analysis: Membrane (adaptive immune system) + | |
| InnateImmunity (TLR pattern matching with inflammation response). | |
| Type or select a prompt and see how both defense layers respond | |
| independently, with matched patterns, threat levels, and a combined verdict. | |
| Run locally: | |
| pip install gradio | |
| python space-membrane/app.py | |
| Deploy to HuggingFace Spaces: | |
