About AI Training Work

AI training is the human side of building modern artificial intelligence. Contributors review model responses, write prompts, rank outputs, and provide structured feedback so AI systems become more accurate, useful, natural, and responsible.

• Help shape how conversational AI understands and responds to people.
• Use language judgment and careful analysis to evaluate model behavior.
• Work remotely with a computer and reliable internet connection.

The Role

OpenTrain AI is seeking a Vietnamese AI Personalization Evaluator to assess how a conversational AI feature uses personal context from prior conversations and connected activity. You will create multi-turn prompts based on personal experiences, review model outputs for appropriate personalization and grounding, and compare responses for helpfulness, ease of use, naturalness, and enjoyment.

This intermediate-level contractor engagement lasts three months and focuses on Vietnamese-language evaluation. The offered rate is $15 per hour.

• Employment type: Contractor and part-time.
• Work arrangement: Remote and worldwide.
• Data type: Text.
• Evaluation types: Response rating and RLHF.
• Availability: 20+ hours per week, with full-time availability required for at least 4 hours per day and up to 40 hours per week.
• Pacific Time overlap: 4 hours required.
• Equipment: Desktop or laptop with reliable internet access.

What You’ll Do

You will evaluate whether personalization reflects prompt intent and is supported by evidence in the available context. Your reviews should identify subtle quality issues and explain rankings with concise, defensible reasoning tied to specific conversation turns.

• Design and execute conversational prompts across approximately one to five turns.
• Create prompts grounded in personal experiences and personal context.
• Check whether responses use relevant context accurately and appropriately.
• Identify incorrect personalization, weak inferences, hallucinations, forced connections, and robotic overnarration.
• Compare two model responses side by side for helpfulness, naturalness, ease of use, enjoyment, and integration.
• Write concise, structured rationales that reference specific conversation turns.
• Review debug information to confirm that summaries and relevant data sources were used correctly.
• Delete evaluation conversations as required to maintain careful data hygiene.

Requirements

Strong Vietnamese reading and writing ability is required. You should be comfortable making nuanced judgments about ambiguous AI responses, designing creative multi-turn prompts, and assessing personalization quality, grounding, integration, and helpfulness.

You must be willing to use a primary personal Google account and enable relevant personal data sources for the evaluation. Reliable independent work habits, clear communication, and precise writing are also important.

• Vietnamese reading and writing proficiency for evaluating model interactions.
• Ability to design creative multi-turn prompts grounded in personal context.
• Judgment for identifying unsupported personalization, hallucinations, and forced connections.
• Ability to compare side-by-side responses for helpfulness, naturalness, and integration.
• Ability to write concise, evidence-based rationales referencing specific conversation turns.
• Reliable computer and internet access.
• Willingness to use a primary personal Google account and enable relevant personal data sources.

Helpful Background

A bachelor’s degree or equivalent experience in policy, law, ethics, linguistics, journalism, computer science, or a related analytical field is relevant to this work. Previous experience in data annotation, AI quality evaluation, content moderation, or a similar review role is preferred.

• Experience evaluating AI-generated content or conversational responses.
• Background in analytical review, structured quality feedback, or content moderation.
• Strong attention to detail when interpreting nuanced language and context.
