40.4 Internationalization schemas (multi-locale outputs)

Multi-Lingual Output

Instead of making 5 calls for 5 languages, ask for all of them at once if the content is short.

The Format

{
  "key": "welcome_message",
  "translations": {
    "en": "Welcome",
    "es": "Bienvenido",
    "fr": "Bienvenue"
  }
}

This ensures consistency. The model sees the English version and translates it in parallel, maintaining the tone across locales.
