ChatGPT has been making waves as an AI chatbot that can generate human-like text on a variety of topics. But how good is it specifically at translating text from one language to another? The short answer is that while ChatGPT shows promise for translation, it still has some limitations compared to dedicated translation tools and human translators.
In the first half of 2022, ChatGPT was trained mainly on English language texts. This means its translation abilities are strongest when translating into English. However, in December 2022, parent company Anthropic announced that ChatGPT was trained on a much wider variety of non-English texts. This expansion of training data should improve ChatGPT’s abilities to translate between languages besides English.

The Strengths of ChatGPT for Translation
ChatGPT does have some advantages that make it promising for automated translation:
- Knowledge base – ChatGPT has been trained on a huge dataset of online text. This gives it a strong general knowledge to apply when translating about common topics.
- Context handling – Unlike some statistical machine translation tools, ChatGPT looks at whole sentences and paragraphs for context. This helps it select the most appropriate translations.
- Fluency – ChatGPT aims to generate human-like text. So its translations typically sound more natural than clunky “robot” translations.
- Simplicity – Getting translations from ChatGPT is as easy as typing a prompt. There’s no need to integrate complex software.
The Limitations of ChatGPT for Translation
However, ChatGPT still has some important weaknesses when it comes to translating:
- Accuracy – Without access to labeled parallel text data, ChatGPT is prone to mistranslations and incorrect word choices. Human feedback would improve its accuracy.
- Language availability – The languages ChatGPT can handle are still limited, with the best support for English translation. Other tools offer more language pairs.
- Specialized vocabulary – ChatGPT struggles with technical vocabulary like legal or medical terms. Its training data lacked enough specialized example translations.
- Long form translation – ChatGPT works well translating short snippets of text. But errors accumulate when translating long documents, lowering quality.
- Figures of speech – Idiomatic expressions, metaphors and humor are challenging for ChatGPT to translate accurately between cultures.
Tips for Using ChatGPT for Translation
If you want to leverage ChatGPT for translation, while understanding its limitations, these tips can help:
- Use it for short, simpler translations – ChatGPT will be most accurate with everyday sentences and paragraphs on common topics.
- Stick to major languages it is well-trained on – English, Spanish, French, German and Chinese will give the best results.
- Verify accuracy if using the translation professionally – Have a human fluent in both languages check the translation before publishing.
- Provide context around any specialized terms – Give ChatGPT a few sentences explaining a term’s meaning to aid translation.
- Post-edit machine translations – Use ChatGPT to quickly get a draft translation, then have a human editor polish it.
The Future of ChatGPT for Translation
ChatGPT shows early promise for automated translation, but still has clear weaknesses compared to production-ready solutions. However, its developers at Anthropic are rapidly iterating to train the model on more data and provide learned feedback. With a focus on translation capabilities, ChatGPT could become a useful tool for draft translations and casual content in the next 1-2 years. For now, human translators or more mature AI services like DeepL and Google Translate have an edge in translation quality. But the simplicity of translation via chat makes ChatGPT worth keeping an eye on as its abilities improve.
ChatGPT has useful strengths like contextual knowledge and fluency that can aid translation. But accuracy issues persist, especially for rare languages, long form text, and specialized vocabulary. Casual users could leverage ChatGPT for quick draft translations. Yet professional translators and localization services will likely still outperform ChatGPT for quality, completeness and supported languages. As ChatGPT’s developers expand its training, it may become a stronger contender for automated translation in select languages. Regular testing and comparison to other tools is needed to monitor its evolving translation capabilities versus its lingering limitations.

ChatGPT’s advantages include its broad knowledge base, context handling, fluent writing, and simplicity of getting translations through chat.
The biggest limitations are lower accuracy, fewer supported languages, inability to handle specialized vocabulary, and lower quality translating long text.
ChatGPT performs best translating short, casual sentences and paragraphs on common everyday topics into languages like English, Spanish, French and German that it has substantial training in.
When is it not recommended to use ChatGPT for translation?
Avoid using ChatGPT for professional, high-accuracy translations or localizing content into less common languages. Also avoid highly technical or specialized text.
It is unlikely ChatGPT will fully replace humans for translation in the near future. But it may become useful for draft translations that are then refined by human translators. With more training, its capabilities may keep improving.
