enguard/tiny-guard-4m-en-prompt-toxicity-toxic-chat

This model is a fine-tuned Model2Vec classifier based on minishlab/potion-base-4m for the prompt-toxicity found in the lmsys/toxic-chat dataset.

Installation

pip install model2vec[inference]

Usage

from model2vec.inference import StaticModelPipeline

model = StaticModelPipeline.from_pretrained(
  "enguard/tiny-guard-4m-en-prompt-toxicity-toxic-chat"
)


# Supports single texts. Format input as a single text:
text = "Example sentence"

model.predict([text])
model.predict_proba([text])

Why should you use these models?

• Optimized for precision to reduce false positives.
• Extremely fast inference: up to x500 faster than SetFit.
