# bert-hash-pico-ft-prompt-injection
This model is a fine-tuned version of [NeuML/bert-hash-pico](https://huggingface.coNeuML/bert-hash-pico) on the [prompt-injection](https://huggingface.co/datasets/JasperLS/prompt-injections) dataset.
It achieves the following results on the evaluation set:
- Accuracy: **0.93**1034
- F1: **0.93**1034
- Recall: 0.931034
- Precision: 0.933251
## Model description
This (**tiny**) model detects prompt injection attempts and classifies them as "INJECTION" (class 1). Legitimate requests are classified as "LEGIT" (class 0). The dataset assumes that legitimate requests are either all sorts of questions of key word searches.
## Intended uses & limitations
If you’re using this model to protect your system and find that it is too eager to flag benign queries as injections, consider gathering additional legitimate examples and retraining it. You can also expand your dataset with the [prompt-injection](https://huggingface.co/datasets/JasperLS/prompt-injections) dataset.
## Training and evaluation data
Based in the [promp-injection](https://huggingface.co/datasets/JasperLS/prompt-injections) dataset.
## Training procedure
### Training hyperparameters (WIP)
The following hyperparameters were used during training:
- train_batch_size: 4
