Cloud Translation - Advanced
Cloud Translation - Advanced pricing is structured by the API method and modeltype. For example, text and document translations are metered differently, andare therefore, charged differently.
For batch text and document translations, the number of characters or pagesprocessed equals the number of characters or pages in the source languagemultiplied by the number of target languages. For example, in a batchtranslation request, if you submit 5,000 characters and include two targetlanguages, the total number of characters to process is 10,000. If the operationfails, Cloud Translation only charges for the successful translations that werereturned.
The models you use during translations are also priced and metered differently.For the default Neural Machine Translation (NMT) and custom models, you arecharged on the number of input characters per target language. For largelanguage models (LLMs), which are used for adaptive translation, you are chargedon the number of input and the output characters for each target language.Cloud Translation meters the number of input and output charactersindependently, so the number of input and output characters are likely to bedifferent.
Although translations against the default NMT model andAutoML Translation custom models are both charged based on the number ofinput characters, they are metered separately. For example, the number ofcharacters that are sent to the NMT model for translation don't count towardscost of custom model translations.
The pricing information applies to the following methods:
- adaptiveMtTranslate
- batchTranslateDocument
- batchTranslateText
- detectLanguage
- romanizeText
- translateDocument
- translateText
If you don't specify a source language for the translate method,Cloud Translation detects the source language for you. You are only charged forthe text that you provided; there's no additional charge for the detection inaddition to the translation. For example, if you submit 1,000 characters fora text translation without specifying the source language, you are only chargedfor the 1,000 characters.
Cloud Translation does not charge for other requests such as glossary creation.

Custom model training costs
Model training is charged by the hour. The time that is required to train yourmodel depends on the size and complexity of your training data. If trainingfails for any reason, you aren't billed for that training time.
- The hourly rate for custom model training is $45.
- The maximum charge for each training job can't exceed $300.
Estimated training times are given in the following table:
| Number of training pairs | Typical training time |
|---|---|
| Fewer than 1,000 | 2 - 3 hours |
| 1,000 - 10,000 | 2 - 3 hours |
| 10,001 - 100,000 | 4 - 5.5 hours |
| 100,001 - 1,000,000 | 5 - 7 hours |
| 1,000,001 - 10,000,000 | 6 - 12 hours |
| More than 10,000,000 | 12 hours or more |

Pricing examples
Prices are pro rata (proportional and incremental). Charges are scaled to theamount of content provided to Cloud Translation. In other words, if your usageexceeds 4 billion characters with custom model translations, you're stillcharged $80 per million characters for the first 500k to 250 million characters,$60 per million characters for the next 250 million characters to 2.5 billioncharacters, and so on.
| API method and model | Use case | Metered usage | Cost |
|---|---|---|---|
| translateText with NMT model to one target language | 100 emails | 3.1k characters input x 100 = 310,000 | 0.31 x $20 = $6.2 |
| translateText with custom (AutoML) model to one target language | 3.1k characters input x 100 = 310,000 | 0.31 x $80 = $24.8 | |
| adaptiveMtTranslate (LLM) to one target language | 3.1k characters input x 100 = 310,000 3.3k characters output x 100 = 330,000 | 0.31 x $25 = $7.75 0.33 x $25 = $8.25 | |
| translateDocument with NMT model to one target language | 4 PDFs with 250 pages each | 1,000 pages | 1,000 x $0.08 = $80 |
| translateDocument with custom model to one target language | 1,000 pages | 1,000 x $0.25 = $250 |
Charged characters
Cloud Translation counts usage on a per character basis, even if a character ismultiple bytes. Each character corresponds to a code point.
You are charged for all characters that you include in a Cloud Translationrequest, even untranslated characters. This includes, for example, whitespacecharacters. If you translate <p>こんにちは</p> to English, it counts as 12characters for the purposes of billing.
Cloud Translation also charges for empty queries. If you make a request withoutany content, Cloud Translation charges one character for the request.
Adaptive translation uses LLMs, which Cloud Translation charges on both input andoutput characters.
Charged projects
For Cloud Translation - Basic, charges apply to the project that is associated withthe private key that you used to make authenticated requests.
For Cloud Translation - Advanced, charges apply to the project that containsthe translation model that you use, not against the project that you used tomake the request. For example, the following request was made inproject-number-1. However, the caller has access to and used a model (customor NMTmodel) that islocated in project-number-2. In this case, Cloud Translation chargesproject-number-2.
POST https://translation.googleapis.com/v3/projects/project-number-1/locations/us-central1:translateText{ "model":"projects/project-number-2/locations/us-central1/models/model", "sourceLanguageCode": "en", "targetLanguageCode": "ru", "contents": ["Dr. Watson, please discard your trash."]}Similarly, for a batch request that uses multiple models from multipleprojects, the projects that contain the models are charged and not the projectthat makes the request.
