Model Card for Model ID
MarianMT English → Hindi Translator (Fine-tuned with QLoRA)
This model is a fine-tuned version of
Helsinki-NLP/opus-mt-en-hi for
English → Hindi translation.
It was trained using
QLoRA parameter-efficient fine-tuning on the
CFILT IITB English-Hindi dataset.
The fine-tuned model shows improved translation quality compared to the base MarianMT model and it is faster than Base Model.

Uses
Direct Use
- Translating English text into Hindi.
- Educational purposes (understanding fine-tuning of translation models).
- Research in low-resource language pairs.
[More Information Needed]
Downstream Use [optional]
- Integrate into chatbots for bilingual English-Hindi conversations.
- Use in document translation pipelines.
- As a teaching resource for NLP model fine-tuning with QLoRA.
Out-of-Scope Use
- Generating misinformation or harmful translations.
- High-stakes environments (medical, legal, safety-critical) without human verification.
[More Information Needed]
Bias, Risks, and Limitations
- May not handle rare domain-specific terms (e.g., medical/legal jargon) correctly.
- May introduce cultural biases or awkward phrasing.
- Performance depends on training dataset; Hindi dialects outside standard Hindi may not be well covered.
