+This model is a fine-tuned version of [ModernBERT-base](https://huggingface.co/answerdotai/ModernBERT-base)  
+trained to **detect prompt injection attempts** in user inputs.  
+
+Prompt injection attacks are attempts to manipulate large language models (LLMs) by inserting malicious instructions into user prompts.  
+This model classifies whether a given text contains signs of such attacks.
