Cloud Translation - Advanced gives you access to state-of-the-art translation models such as the Translation LLM and other custom AutoML models in addition to the default Google Neural Machine Translation (NMT) model available with Cloud Translation - Basic. Use this table to decide on the best model for your use case.
| Model | Description | Model ID |
|---|---|---|
| Translation LLM |
Highest quality translation model - a Large language model (LLM) powered by Gemini and fine-tuned for translation to provide the highest quality translations at fast latencies (2x faster latency than Gemini 2.0 Flash). |
general/translation-llm |
| Neural Machine Translation (NMT) model |
Fastest translation model - ideal for real time and latency critical use cases. |
general/nmt |
| Custom Translation LLM (Preview) |
Provides high quality translation customization via fine-tuning of the Translation LLM with domain-specific training data for given language pairs. This is a new version of the model that is coming to GA in mid 2025. |
translation-llm-custom/{model-id} |
| Adaptive Machine Translation models |
Translation LLM with real-time, lightweight customization support for adaptive translation that you can provide with a dataset of translation examples. |
general/translation-llm-adaptive |
| AutoML Translation model | Domain specific text. You provide training data specific to your use cases, for given language pairs to customize Google's NMT model for the domain purpose. | The model ID is generated after model training completes |
Note that each model supports its own set of languages. Refer to the Supported languages guide to ensure that your source and target languages are supported.
