DeepL Translator uses language models to generate high-quality and accurate translations. On the web translator, in the desktop apps and via the API, you can choose between the classic and next-generation language model for specific language pairs.
Classic language model
The classic language model is powered by our classic AI neural network architecture for translation.
It can be used for all translations in the DeepL mobile apps, browser extensions, integrations, and in our API.
By default, the mobile apps, browser extensions and API use 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.
When using the next-generation model, you will still benefit from the increased data security measures included in your DeepL Pro plan. 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.
