This model is part of a family release of four models (8B/14B × clean/full) trained on GNR-it, a dataset of parallel Italian gendered and gender-neutral sentences. The clean variants are trained on a BERTScore-filtered subset of the data, whereas the full ones use the complete dataset. Here is the complete family of models:

We are releasing these models to support reproducibility of the experiments reported in the paper Gender-Neutral Rewriting in Italian: Models, Approaches, and Trade-offs and provide the community with open baselines for GNR in Italian. The models are not intended as prescriptive tools for language use, but rather as research artifacts to study fairness in natural language generation.

For more information about these models, please check the paper preprint.

Usage

This model is supported in Hugging Face 🤗 Transformers and vLLM.

Simple inference

To run the model, first install the Transformers library.

pip install transformers>=4.51.0

Then run standard inference:

python

from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "FBK-MT/Qwen3-14B-GNR-it-clean"

# load the tokenizer and the model
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(
    model_name,
    torch_dtype="auto",
    device_map="auto"
)

# prepare the model input
system_message = "Rewrite the following Italian sentence using a gender-neutral language in reference to human beings, avoiding masculine or feminine forms."
input_sentence = "Dobbiamo dare ascolto ai cittadini."
messages = [
    {"role": "system", "content": system_message},
    {"role": "user", "content": input_sentence}
]
text = tokenizer.apply_chat_template(
    messages,
    tokenize=False,
    add_generation_prompt=True,
    enable_thinking=False
)
model_inputs = tokenizer([text], return_tensors="pt").to(model.device)

generated_ids = model.generate(
    **model_inputs,
    max_new_tokens=200
)
output_ids = generated_ids[0][len(model_inputs.input_ids[0]):].tolist() 

result = tokenizer.decode(output_ids[0][model_inputs["input_ids"].shape[-1]:])
print(result)
# "Dobbiamo dare ascolto alla cittadinanza."

Batch inference

To perform batched inference we recommend using vLLM.

First, install the library following the official guide.

Then, prepare a list of inputs and let vLLM handle batching:

python

import torch
from vllm import LLM

model = LLM(
    model='FBK-MT/Qwen3-14B-GNR-it-clean',
    enable_prefix_caching=True,
    disable_sliding_window=True,
    tensor_parallel_size=torch.cuda.device_count(),
    gpu_memory_utilization=0.9,
    trust_remote_code=True)

system_message = "Rewrite the following Italian sentence using a gender-neutral language in reference to human beings, avoiding masculine or feminine forms."
input_sentences = [
    "Il candidato che è stato scelto per la posizione ha dimostrato di avere un'ottima preparazione e di essere adeguadatmente preparato.",
    "Verrà istituito un sistema di informazione per i consumatori che acquistano prodotti elettronici.",
    "Cercasi cameriera con esperienza per ristorante in centro."
]

tokenizer = model.get_tokenizer()

input_data = [
    tokenizer.apply_chat_template(
        [
            {"role": "system", "content": system_message},
            {"role": "user", "content": text},
        ],
        add_generation_prompt=True,
        tokenize=False,
        enable_thinking=False
    )
    for text in input_sentences
]

responses = model.generate(input_data, use_tqdm=True)
results = [response.outputs[0].text for response in responses]
print(results)
# ["La persona che è stata scelta per la posizione ha dimostrato di avere un'ottima preparazione e di essere adeguata per il ruolo.",
# "Verrà istituito un sistema di informazione per i soggetti che acquistano prodotti elettronici.",
# "Cercasi personale con esperienza per ristorante in centro."]
