Model Overview

MET-D-Qwen3-4B-ms-only is a specialized 4 billion parameter model, fine-tuned from Qwen3-4B, designed for Malay-only moral reasoning. Its core function is to evaluate actions within moral dilemmas from a specific character's perspective, providing a judgment on acceptability and emotional discomfort. The model generates an explicit chain-of-thought reasoning trace before delivering its final answer, all in Malay.

Key Capabilities

  • Character-Perspective Moral Reasoning: Judges actions based on a given character's description within a moral dilemma.
  • Detailed Reasoning Traces: Provides a step-by-step explanation for its judgments, crucial for understanding complex moral evaluations.
  • Emotional Discomfort Assessment: Determines if performing or not performing an action would cause emotional/mental discomfort for the character.
  • Malay Language Focus: This specific checkpoint is exclusively trained and operates in Malay, making it highly suitable for Malay-language applications.
  • Rejection-Sampling for Accuracy: Utilizes self-generated reasoning traces, rejection-sampled against ground truth based on theoretical grounds, to ensure robust and verifiable outputs.

Use Cases

  • Ethical AI Development: Useful for building AI systems that require nuanced moral understanding in a Malay context.
  • Content Moderation: Can assist in evaluating the moral implications of content in Malay.
  • Research in Moral Philosophy: Provides a tool for exploring character-specific moral judgments and reasoning in Malay.

This model is part of the broader MET collection, which offers similar moral reasoning capabilities across various base models and languages.
