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

A sequence-to-sequence translation model fine-tuned on English–German sentence pairs. This model translates English text into German and is built using the Hugging Face MarianMTModel. It’s suitable for general-purpose translation, language learning, and formal or semi-formal communication across English and German.

✨ Model Highlights

📌 Base Model: Helsinki-NLP/opus-mt-en-de
📚 Fine-tuned on a cleaned and tokenized parallel English-German dataset
🌍 Direction: English → German
🔧 Framework: Hugging Face Transformers + PyTorch

🧠 Intended Uses

✅ Translating English content (emails, documentation, support text) into German
✅ Use in educational platforms for learning German
✅ Supporting cross-lingual customer service, product documentation, or semi-formal communications

🚫 Limitations

❌ Not optimized for informal, idiomatic, or slang expressions
❌ Not ideal for legal, medical, or sensitive content translation
📏 Sentences longer than 128 tokens are truncated
⚠️ Domain-specific accuracy may vary (e.g., legal, technical)

🚀 Usage

from transformers import AutoTokenizer, AutoModelForSeq2SeqLM
import torch

model_name = "AventIQ-AI/Ai-Translate-Model-Eng-German"
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")
    model.to(device)
    inputs = tokenizer(text, return_tensors="pt", padding=True, truncation=True).to(device)
    outputs = model.generate(**inputs)
    return tokenizer.decode(outputs[0], skip_special_tokens=True)

# Example
print(translate("How are you doing today?"))
