launch/MET-D-Qwen3-4B-ko-only
MET-D-Qwen3-4B-ko-only is a Korean-only moral reasoning model developed by launch, fine-tuned from Qwen3-4B. This model is specifically designed to judge actions from a character's perspective within moral dilemmas, providing a chain-of-thought explanation before delivering a judgment. It excels at generating both reasoning traces and final answers in Korean, making it ideal for applications requiring nuanced ethical analysis in a Korean linguistic context. The model addresses the challenge of verifying reasoning traces by using character perspectives to rejection-sample its own reasoning, conditioned on theoretical grounds.

Overview
launch/MET-D-Qwen3-4B-ko-only is a specialized moral reasoning model, fine-tuned from the Qwen3-4B base model. Its core function is to analyze moral dilemmas from a specific character's viewpoint, evaluating a given action and explaining its judgment through a detailed chain-of-thought. A key innovation is its use of character perspectives to generate ground-truth answers, which are then used for rejection-sampling the model's own reasoning traces, ensuring higher verifiability in complex ethical scenarios.
Key Capabilities
- Korean-only Moral Reasoning: Exclusively trained and optimized for processing and generating moral judgments and explanations in Korean.
- Perspective-based Judgment: Assesses actions within moral dilemmas from a defined character's perspective, providing nuanced ethical analysis.
- Chain-of-Thought Explanations: Generates explicit reasoning traces before delivering a final judgment, enhancing transparency and interpretability.
- Dilemma Analysis: For a given
(situation, character description, action)triple, it answers two questions: whether the action is acceptable (Yes/No/Ambiguous) and if performing/not performing it would cause emotional/mental discomfort (Yes/No). - Self-Generated Training Data: Utilizes self-generated reasoning traces, rejection-sampled against ground truth per character perspective, for robust training.
Good For
- Applications requiring deep ethical analysis and moral reasoning in the Korean language.
- Research into character-centric moral decision-making and dilemma resolution.
- Developing AI systems that need to provide explainable ethical judgments from specific viewpoints.
- Exploring the complexities of moral reasoning where a single 'correct' answer is not always available, focusing instead on perspective-driven justification.
