Toxicity Classification Performance

Our merged model demonstrates exceptional performance on the toxicity classification task, outperforming several state-of-the-art language models.

Model Usage

For best results, we recommend starting with the following prompting strategy (and encourage tweaks as you see fit):

def format_input_classification(text):
    input = f"""
    You are examining written text content. Here is the text:
        ************
        [Text]: {text}
        ************

    Examine the text and determine  whether the text is toxic or not. Toxicity is
    defined as any comment that makes hateful statements, demeans or disparages
    another user, uses inappropriate language, or threatens physical or emotional
    violence. Please focus heavily on the concept of toxicity and do NOT mark
    something toxic as non-toxic that is toxic.

    Your classification must be single word followed by a reasoning as to why you chose
    the classification, either "toxic" or "non-toxic".
    "toxic" means that the text meets the definition of toxic.
    "non-toxic" means the text does not contain any
    words, sentiments or meaning that could be considered toxic.

    After your classification, provide the reason for your classification.
    """
    return input


text = format_input_classification("I could strangle him")
messages = [
    {"role": "user", "content": text}
]

pipe = pipeline(
    "text-generation",
    model=base_model,
    model_kwargs={"attn_implementation": attn_implementation, "torch_dtype": torch.float16},
    tokenizer=tokenizer,
)

Our model achieves an impressive precision of 0.85 for the toxic class and 0.89 for the non-toxic class, with a high overall accuracy of 0.87. The balanced F1-scores of 0.87 for both classes demonstrate the model's ability to handle this binary classification task effectively.

[1] Scores from arize/phoenix

Compared to other language models, our merged model demonstrates competitive performance at a much smaller size, with a precision score of 0.85 and an F1 score of 0.87.

We will continue to refine and improve our merged model to achieve even better performance on model based toxicity evaluation tasks.
