# Marian NMT

Marian NMT is an open-source framework for neural machine translation. It is built for technical teams, researchers, and developers who want to train, evaluate, or operate translation models themselves.

That makes Marian different from end-user translators like DeepL or Google Translate. It is a model and infrastructure component for custom NMT workflows.

## Who is it for?

Marian fits research, NLP teams, language services, and companies with specific requirements for translation models. For individual text translation, a finished translation service is more practical.

## Typical use cases

- Train or evaluate custom NMT models
- Integrate translation systems into technical pipelines
- Test language pairs, domains, and model quality in a controlled way
- Reproduce machine-translation research

## Core features

- Framework for neural machine translation
- Open-source and research-oriented use
- Suitable for training, decoding, and evaluation
- Technical control over models and data

## Pros and cons

### Pros

- Strong for custom NMT research and infrastructure
- No external SaaS dependency
- Control over data, models, and deployment

### Cons

- High technical entry barrier
- Not a finished business app for occasional translation
- Operation and quality assurance stay with the team

## Workflow fit

Marian NMT is for teams that want control over translation. If you only want to translate a text quickly, do not start here.

## Privacy & data notes

Marian can run locally or in your own infrastructure. That is useful for sensitive language data, but it shifts responsibility for security, logging, and model artifacts to the operator.

## Pricing & costs

Marian is open source. Costs come from hardware, training data, engineering, and ongoing operation.

## FAQ

**Is Marian NMT for normal users?**

No. It is a developer and research framework.

**Can Marian run locally?**

Yes. It is designed for custom technical environments.

**Is Marian better than DeepL?**

That is not a direct comparison: Marian is a framework, DeepL is a finished service.
