Will duplicating a custom translation model incur training costs again?

Question

I have a Hungarian-English Custom translation model trained and deployed in my workspace. I had previously trained it with around 100k unique sentence pairs and it cost me the maximum training cost $300 . Now I have some more domain specific sentences I'd like to use for finetuning the model further. If I were to duplicate the current model and include the new documents as well, will the process cost me the same amount again? or will it just be charged for the new sentence pairs provided? I could not find anything related to the cost of duplicating model in the official guides.

Hello @Apiseg Rajendran,

Duplicating a custom translation model in Azure and adding new domain-specific sentences, you will not incur the same training costs as the initial training. Azure Custom Translator only charges for the new, unique sentence pairs that are added for finetuning. The system automatically de-duplicates the training data, ensuring that previously used sentence pairs from the original model do not incur additional costs.

If you duplicate your Hungarian-English model and include new documents, you will only be charged for the new sentence pairs that were not part of the original training. Since you’ve already reached the $300 cap for the initial 100k sentence pairs, any additional costs will be based solely on the new data and will be billed proportionally. The cost will not exceed the next cap tier unless the total number of sentence pairs exceeds that threshold.

Please refer this Azure AI Translator pricing.

I Hope this helps. Do let me know if you have any further queries.
