About AI Training and Localization

AI training is the human side of building artificial intelligence. People review model outputs, write examples, rate responses, translate content, and provide feedback that helps AI systems become more accurate, useful, and culturally appropriate.

Localization experts play an important role by checking terminology, tone, meaning, and cultural nuance. Your judgment helps ensure that AI-generated content works naturally for Mandarin-speaking audiences while following the original prompt and intended meaning.

• Evaluate and improve generative AI responses
• Apply language, editorial, and cultural judgment
• Help shape how modern AI systems communicate
• Build experience in a fast-growing field with flexible project work

The Role

OpenTrain is seeking a Chinese Mandarin AI Evaluation and Localization Expert to assess AI-generated responses and provide detailed feedback. You will evaluate reasoning quality, accuracy, clarity, logical consistency, and adherence to prompts.
