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.

Azure Translator

$10 per million characters pay as you go, 2 million free a month on F0, commitment overage down to $5.50. The 2026-06-06 schema breaks v3.0 clients and drops BreakSentence and dictionary lookups from the spec.

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

Azure Translator

  1. Send Ocp-Apim-Subscription-Region with the key for a regional resource
  2. Pin api-version=3.0 until your client handles the 2026-06-06 inputs and value shape
  3. Batch up to 1,000 strings a call rather than one call per string
  4. Spread load across the hour, since the character caps are hourly and bursts get 429
  5. Treat 403001 as the free quota running out, not a permissions error
