*Marian* is an efficient Neural Machine Translation framework written in pure
C++ with minimal dependencies.

Named in honour of Marian Rejewski, a Polish mathematician and cryptologist.

Main features:

- Efficient pure C++ implementation
- Fast multi-GPU training and GPU/CPU translation
- State-of-the-art NMT architectures: deep RNN and transformer
- Permissive open source license (MIT)
- [more detail...](https://marian-nmt.github.io/features)

## Amun

The handwritten decoder for RNN models compatible with Marian and Nematus has
been superseded by the Marian decoder. The code is available in a separate
repository: https://github.com/marian-nmt/amun
