What can you expect from our next-gen model?
There’s lots to be excited about with our next-gen model. Let’s cover the most important topics.
Groundbreaking technology that outperforms competitors
DeepL’s models are trained on the highest-quality linguistic data, with an unwavering focus on excellence. Combining world-class AI with the expertise of thousands of hand-picked language specialists who “tutor” the model, DeepL consistently provides best-in-class translation.
In fact, recent blind tests show that language experts routinely prefer DeepL's translations. According to the data, DeepL’s translation is preferred:
1.3x more often than Google Translate
1.7x more often than ChatGPT-4
2.3x more often than Microsoft
But that’s not all. Thanks to specialized LLMs, which are uniquely tuned for language, DeepL’s more human-like translations also have a reduced risk of hallucinations and misinformation. This is especially important for enterprises looking to scale operations with a trusted AI solution.
Furthermore, unlike general purpose models that train with data pulled from the public internet, DeepL’s model leverages over seven years of proprietary data specifically tuned for translation and content creation.
Highest-quality translations on the market
Starting with Japanese, German, and Simplified Chinese to and from English, with many more languages to come, this step forward continues to improve on the top-notch translations that DeepL’s web translator provides. With the innovations of the next-gen model, DeepL Translator provides the highest quality translations on the market.
The quality of our next-gen models was confirmed via our previously mentioned blind tests, which were conducted with leading language experts. In these tests, the quality of the LLM-powered translations compared to the “classic” model was determined—with the new model coming out on top for each test.
Japanese ←→ English: the quality of the next-gen model is 1.7x better than the classic model
Simplified Chinese ←→ English: the quality of the next-gen model is 1.7x better than the classic model
German ←→ English: the quality of the next-gen model is 1.4x better than the classic model
This improved translation quality will not only save your company time, but also allow your teams to streamline communications across global markets.
Improve productivity to save more time and money
Our next-generation model will help your enterprise get even more value from DeepL. In fact, blind tests also found that DeepL’s translations require fewer edits than competitors, with Google Translate needing 2x more edits and ChatGPT-4 needing 3x more edits to achieve the same quality.
Thus, our new LLMs improve knowledge worker productivity by decreasing the time spent on translation and copy editing, allowing your teams to focus on the jobs that matter the most.
In fact, in the 2024 study conducted by Forrester Consulting, “The Total Economic Impact™ of DeepL”, it was discovered that DeepL reduced translation time by 90% and cut translation workloads by 50%—resulting in a 345% ROI.*
