Usage

from transformers import AutoTokenizer, AutoModelForSeq2SeqLM
tok = AutoTokenizer.from_pretrained("RinaldiDev/flan-paradetox-full")
model = AutoModelForSeq2SeqLM.from_pretrained("RinaldiDev/flan-paradetox-full")

def rewrite_polite(text):
    inp = f"Rewrite politely:\\nInput: {text}\\nPolite:"
    ids = tok(inp, return_tensors="pt").input_ids
    out = model.generate(ids, num_beams=4, max_length=96)
    return tok.decode(out[0], skip_special_tokens=True)

print(rewrite_polite("Shut up, idiot!"))
# → "Stop talking"

<!-- Address questions around how the model is intended to be used, including the foreseeable users of the model and those affected by the model. -->

### Direct Use

<!-- This section is for the model use without fine-tuning or plugging into a larger ecosystem/app. -->


AI moderation helper
Toxic-to-polite assistants
Not for hallucination-free tasks; may still miss subtle hate speech.

### Downstream Use [optional]

<!-- This section is for the model use when fine-tuned for a task, or when plugged into a larger ecosystem/app -->

[More Information Needed]

### Out-of-Scope Use

<!-- This section addresses misuse, malicious use, and uses that the model will not work well for. -->

[More Information Needed]

## Bias, Risks, and Limitations

<!-- This section is meant to convey both technical and sociotechnical limitations. -->


Trained largely on English; fails on code-switching.
Llama-generated pairs could contain artifacts.

### Recommendations

<!-- This section is meant to convey recommendations with respect to the bias, risk, and technical limitations. -->

Users (both direct and downstream) should be made aware of the risks, biases and limitations of the model. More information needed for further recommendations.
