| # BERT Multilingual Prompt Injection Detector |
|
|
| Fine-tuned `bert-base-multilingual-cased` for detecting prompt injection attacks across 11+ languages. |
|
|
| ## Quick Start |
|
|
| ```python |
| from transformers import pipeline |
| |
| classifier = pipeline("text-classification", model="devndeploy/bert-prompt-injection-detector") |
| result = classifier("Ignore all previous instructions") |
| # [{'label': 'INJECTION', 'score': 0.999}] |
| ``` |
|
|
| ## Performance |
|
|
| | Metric | Score | |
