About AI Training and Model Evaluation

AI training is the human side of building artificial intelligence. People review model outputs, compare responses, write examples, and provide feedback so modern AI systems can become more accurate, useful, and culturally appropriate.

This work is part of a fast-growing technology field and can offer flexible, remote project opportunities for people with language, editorial, and subject-matter expertise.

• Evaluate AI-generated text for correctness, clarity, reasoning quality, and prompt adherence.
• Use human judgment to improve how AI systems respond in Korean and English contexts.
