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.
DeepL被誉为世界上最准确的机器翻译服务。其翻译引擎基于神经网络人工智能开发，根据其披露的专业翻译盲测结果，DeepL的表现比竞争对手高出3：1，在英译质量盲测中，甚至比其他机器翻译引擎高出5倍。

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.
OpenAI 的 GPT 模型是在大量文本数据上训练的，这意味着它在处理各种专业术语时表现得非常出色。它擅长理解句子或段落的上下文，经过广泛的比较，得出的结论是，OpenAI 的翻译质量目前在大多数情况下都是最好的。
However, due to OpenAI's core mechanism of sequentially predicting each word in a sentence, its translation speed is relatively slow.
然而，由于 OpenAI 的核心机制是按顺序预测句子中的每个单词，因此其翻译速度相对较慢。
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.
此外，由于 OpenAI 不是专门作为翻译服务创建的，因此它有一些安全限制，例如拒绝翻译具有某些负面含义的段落。
Lastly, as it is still in its early stages, the service may sometimes be relatively less stable.
最后，由于它仍处于早期阶段，该服务有时可能相对不太稳定。
