April 2025, Paris, France – Lingua Custodia, a leading European Fintech company specialising in AI models for finance, announces the release of six translation models specialised for the financial domain. These new models deliver superior translation quality while consuming significantly fewer computational resources.

As highlighted in the Scaling Laws of Decoder-Only Models on the Multilingual Machine Translation Task research paper (2024), Lingua Custodia’s models outperform large-scale language models such as LLaMA, Mistral, and TowerInstruct in financial translation across 11 language directions.

“Machine translation is a major application of Generative AI, but many existing models require extensive computational power,” says Olivier Debeugny, CEO of Lingua Custodia. “Our models are optimised for financial translation, achieving higher accuracy while being significantly smaller and more energy efficient. This translates to a reduced carbon footprint without compromising performance.”

Developed from scratch on in-house data, these models are trained using financial data.  To foster innovation and collaboration, Lingua Custodia is releasing three of these models as open source, making them accessible to the broader AI and financial communities.
