DeepL is known as the world's most accurate machine translation service. Its translation engine is developed based on neural network artificial intelligence, and according to its disclosed professional translator blind test results, DeepL outperforms its competitors by a factor of 3: 1, and in the blind test of translation quality in English ⇄ Chinese, it is even 5 times higher than other machine translation engines.

The GPT model by OpenAI is trained on a large amount of textual data, which means it performs exceptionally well when dealing with various professional terms. It excels in understanding the context of sentences or paragraphs, and after extensive comparisons, the conclusion is that OpenAI's translation quality is currently among the best in most cases. However, due to OpenAI's core mechanism of sequentially predicting each word in a sentence, its translation speed is relatively slow. Additionally, since OpenAI is not specifically created as a translation service, it has some security limitations, such as refusing to translate paragraphs with certain negative meanings. Lastly, as it is still in its early stages, the service may sometimes be relatively less stable.
