About Marian

Marian is a fast, self-contained neural machine translation (NMT) framework written entirely in C++. It integrates an automatic differentiation engine based on dynamic computation graphs, enabling efficient training and translation within an encoder-decoder architecture. The framework is designed for both research and deployment, balancing high performance with extensibility and ease of experimentation. Marian is open-source and available as a research toolkit, with its design and capabilities documented in a paper on arXiv.
