Language Model (optional)
The type of translation model and vendor to use. Currently we only support Google as a vendor. Text is billed in 100 character intervals and pricing is based on the model selected.
- [Google] Large Language Model: use Google’s LLM to translate text. The LLM supports fewer language pairs than the NMT model, but large language models tend to generate more natural sounding translations.
- [Google] Neural Machine Translation: use Google’s NMT model. The NMT model supports many more language pairs, but may not be as natural sounding as a LLM.
Translate From (required if Language Model is selected)
The language to translate from. The input text should be typed in this language. Automatic language detection is only supported if the user chooses to use the NMT model.
