What is Google Cloud Translation API?

Discover how Google Cloud Translation API can enhance your workflow

Cloud Translation supports two editions called Basic and Advanced. Basic offers NMT for text and language detection with a monthly free credit applied across editions. Advanced adds document translation glossary and custom models and now includes LLM based modes for adaptive and text translation. Pricing is transparent and metered per character with a first half million characters free each month as credit then standard NMT at a per million character rate while LLM adaptive and output metering are documented separately. Teams integrate through REST or client libraries and batch jobs handle large workloads with per page pricing for supported document formats. Glossaries maintain brand terms while datasets can train custom models for domain language. Security follows Google Cloud policies with regional data handling IAM controls and audit logs. Typical uses include product localization support knowledge translation multilingual chat and analytics. The value is proven scale predictable billing and multiple model paths when cost or quality tradeoffs matter.

Frequently Asked Questions

What is the current entry pricing and free usage?
Cloud Translation applies a monthly free credit worth five hundred thousand characters across editions then charges per million characters as documented on the pricing page.
How do LLM and NMT pricing differ today?
LLM text charges both input and output while standard NMT charges on input only and adaptive LLM has a higher per million character rate for both directions.
Can we translate documents without losing layout?
The Advanced edition supports supported formats with per page pricing that preserves structure better than ad hoc copy and paste routines.
How do glossaries keep brand terminology consistent?
Glossaries map source to approved target terms and apply during calls so names and phrases remain correct across channels and releases.
Is language detection billed separately?
For NMT text calls detection is included and charges only the provided characters so there is no extra fee just for detecting language.
What about data security and residency controls?
Google Cloud IAM audit logging and regional options apply which allows governance choices for regulated industries and public sector teams.
When should we train a custom model vs use LLM text?
Use custom models for narrow domains with stable terminology while LLM text can help with nuanced phrasing and mixed contexts without training.
How can we estimate costs for large imports?
Use the pricing calculator and batch jobs with page pricing to project spend then monitor character counts per release to avoid surprises.
