Language Pair Explorer

The Translator API requires you to check availability for a specific source→target language pair before creating a translator. Pair availability can be readily (model cached), after-download (model needs fetching), or no. This explorer checks any pair and shows a matrix of common language combinations.

const capabilities = await self.ai.translator.capabilities();
const available = capabilities.languagePairAvailable('en', 'fr');
// 'readily' | 'after-download' | 'no'

if (available === 'no') {
  console.log('Pair not supported');
} else {
  const translator = await self.ai.translator.create({
    sourceLanguage: 'en',
    targetLanguage: 'fr',
    // 'after-download' will trigger model download here
  });
  const result = await translator.translate('Hello, world!');
  console.log(result); // 'Bonjour, monde!'
}
