🧠 MarianMT-Text-Translation-AI-Model-"en-fr"

A sequence-to-sequence translation model fine-tuned on English–French sentence pairs. This model translates English text into French and is built using the Hugging Face MarianMTModel. It’s ideal for general-purpose translation, educational use, and light regulatory or formal communication tasks between English and French.

✨ Model Highlights

📌 Based on Helsinki-NLP/opus-mt-en-fr
🔍 Fine-tuned on a cleaned parallel corpus of English-French sentence pairs
⚡ Translates from English → French
🧠 Built using Hugging Face Transformers and PyTorch

🧠 Intended Uses

✅ Translating English feedback, emails, or documents into French
✅ Cross-lingual support for customer service or regulatory communication
✅ Educational platforms and language learning

🚫 Limitations

❌ Not suitable for informal slang or code-mixed inputs
📏 Inputs longer than 128 tokens will be truncated
🤔 May produce less accurate translations for highly specialized or domain-specific language
⚠️ Not intended for legal, medical, or safety-critical translations without expert review

🚀 Usage

from transformers import AutoTokenizer, AutoModelForSeq2SeqLM
import torch

model_name = "AventIQ-AI/MarianMT-Text-Translation-AI-Model-en-fr"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForSeq2SeqLM.from_pretrained(model_name)
model.eval()

def translate(text):
    device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
    finetuned_model.to(device)
    inputs = tokenizer(text, return_tensors="pt", padding=True, truncation=True).to(device)
    outputs = finetuned_model.generate(**inputs)
    return tokenizer.decode(outputs[0], skip_special_tokens=True)

# Example
print(translate("Hello, how are you?"))
