AI translation for enterprises

Language Weaver Pro

Fluent, context-aware AI Translation model designed for enterprise security and accuracy

Purpose-built, not repurposed

Most AI translation tools are general-purpose models doing a specialist job. The result: inconsistent output, data exposure risk and no accountability when accuracy matters.

Language Weaver Pro is different. A 100+ billion parameter model purpose-trained for translation — delivering fluent, context-aware output for enterprises and government organisations where accuracy, security and compliance are non-negotiable.

What is the difference between existing Language Weaver and Language Weaver Pro?

Language Weaver Pro is RWS's next-generation LLM-based MT model, built in partnership with Cohere. Unlike existing Language Weaver neural MT models, LW Pro is built on large language model architecture, enabling a superior handling of context, ambiguity and complex content including high-end marketing and creative copy. In head--to-head human evaluation conducted in January- February 2026, LW Pro outperformed DeepL NextGen overall across multiple language directions and domains at both sentence and paragraph level.

Will the model be available via Language Weaver's existing connectors or APIs?

Yes. Language Weaver Pro is accessible via the Language Weaver API, enabling integration into existing workflows, TMS connectors and enteprise systems without requiring architectural changes.

How can I ensure with Language Weaver Pro my data is safe and secure?

Language Weaver follows strict security and compliance standards, including encryption, access controls, and data isolation. The platform is designed to support the confidentiality requirements of global enterprises and no content is shared externally or used to train any third-party models.
