## Verdicts

**Amazon Translate.** IAM policies scope access per action and resource, with a `TranslateReadOnly` managed policy, and CloudTrail logs each call. AWS may store and use text to improve Amazon AI services unless the organisation sets an opt-out policy.

**Google Cloud Translation.** 500,000 free characters a month from a $10 credit, and only successful translations bill. Basic (v2) documents the API key as a URL query parameter.

## Before you call either

### Amazon Translate

1. Chunk real-time text under 10,000 bytes, not characters, so multibyte scripts fit less per call
2. Pass `SourceLanguageCode` auto to detect the source language, and handle `DetectedLanguageLowConfidenceException`
3. Read `AppliedSettings` in the response, since unsupported formality or profanity settings are dropped without an error
4. Retry `TooManyRequestsException` with backoff, which the AWS SDKs do by default
5. Set the AI services opt-out policy before sending private text

### Google Cloud Translation

1. Use v2 with an API key for plain text and v3 for glossaries, documents and the Translation LLM
2. Set `mimeType` to text/plain on v3 when the input isn't HTML
3. Back off on 403 User Rate Limit Exceeded as you would on a 429
4. Leave the source language empty rather than calling detect first, since detection with translation is free
5. Keep requests near 5,000 characters. v3 rejects more than 30,000 code points
