--- title: Multilingual Text Understanding Model + Language Detection! slug: changelog/multilingual-text-understanding-model-language-detection type: added createdAt: 'Mon Dec 12 2022 15:52:44 GMT+0000 (Coordinated Universal Time)' hidden: false description: >- Cohere's multilingual model now supports semantic search across 100 languages with a single index. --- **[NOTE: `co.detect_language()` is deprecated.]** Cohere's multilingual text understanding model is now available! The `multilingual-22-12` model can be used to semantically search within a single language, as well as across languages. Compared to keyword search, where you often need separate tokenizers and indices to handle different languages, the deployment of the multilingual model for search is trivial: no language-specific handling is needed — everything can be done by a single model within a single index. In addition to our new model, you can now detect the language of a data source using `co.detect_language()` endpoint. For more information, see our [multilingual docs](/docs/multilingual-language-models).
