What is the next-generation language model?
DeepL Translator uses language models to generate high-quality and accurate translations. On the web translator and in the desktop apps, you have the option to choose between two different language models for translation for specific language pairs:
This article helps you learn more about these two language models offered for DeepL Translator.
Classic language model
The classic language model is powered by our classic AI neural network architecture for translation.
The classic language model is used for all translations in the DeepL mobile apps, browser extensions, integrations, and in our API.
By default, the web translator uses the classic language model.
While the next-generation language model promises improved translation quality, the classic still provides users with highly accurate and nuanced translations.
The classic language model is supported for all languages offered by DeepL.
More information about the translation quality of our classic language model can be found here.
Next-generation language model
The next-generation (or “next-gen”) language model is powered by a large language model (LLM) infrastructure. Our large language model uses a large number of texts in various languages to solve complex problems and is specialized for translations.
The use of our own LLMs for the next-gen language model provides improved quality for the translation of your input texts, especially texts that are longer.
In the web translator or desktop apps, you can choose between the classic language model and the new next-gen language model for text translations. You can switch between these models via a dropdown menu in the translation area for all supported language pairs.
This dropdown menu is currently only available for translations for the following languages:
- English ↔Chinese
- English ↔ German
- English ↔ Japanese
- Chinese ↔ German
- Chinese ↔ Japanese
- German ↔ Japanese
There will be more languages to come.
Note: The next-generation language model is not available for DeepL Translator users without a paid plan, users of the DeepL API plans, or DeepL Write Pro.
You will still benefit from the increased data security measures included in your DeepL Pro plan while using the next-gen language model. More information about this can be found in our privacy policy.
Additional features for DeepL Translator including the glossary, formal/informal tone and alternatives are also available while using the next-generation language model.
