artist_weights: A Constraint System for Building Consistent Personalities in Large Language Models

This project proposes a centralized personality logic and style constraint system aimed at addressing the challenge of LLMs maintaining stable identity traits across multiple scenarios. By defining language parameters, personality architecture, and few-shot reference sets, it ensures models produce high-fidelity and consistent content in tasks like lyric writing and brand storytelling. Its core value lies in upgrading temporary prompts to structured configurations, enabling personality reuse, maintenance, and scalability.

While LLMs can generate fluent text, they face difficulties maintaining long-term consistent personality traits in scenarios like virtual characters and brand voices. Traditional prompt engineering has issues such as limited prompt length, low efficiency, and conversation drift, making it hard to meet complex personality needs.

The core design principles of artist_weights include: centralized management (storing personality definitions in a unified repository, supporting version control and cross-project reuse), layered architecture (breaking down into core identity, language style, etc.), parameterized expression (converting abstract features into quantifiable parameters), and few-shot learning (allowing models to learn personality traits through example sets).

The system consists of four core components:

1. Personality Architecture: Divided into identity layer ("Who am I"), language layer ("How to express"), knowledge layer ("What I know"), and interaction layer ("How to communicate");
2. Language Parameters: Configurable values like formality level and emotional intensity, supporting combination into preset styles;
3. Few-shot Reference Set: Includes input examples, output examples, and annotations covering multiple scenarios;
4. Constraint Rule Base: Defines "red line" rules such as forbidden vocabulary and prohibited topics.

Applicable to multiple scenarios:

• Brand Voice Management: Unify the tone of enterprise content;
• Virtual Character Development: Create stable characters like game NPCs and virtual idols;
• Creative Collaboration: Act as an AI collaborator for artists to maintain consistent creative styles;
• Multilingual Localization: Keep core personality unchanged while adapting language layer parameters to target languages.

Points to note when using:

• Model Dependence: Different LLMs respond differently to personality prompts, requiring targeted adjustments;
• Long-term Consistency: Ultra-long conversations may drift, so personality context needs regular refreshing;
• Complex Personality Difficulty: Contradictory or overly complex definitions can easily confuse the model;
• Ethical Considerations: Need to guard against bias and inappropriate content risks.

artist_weights promotes AI personality engineering from art to engineering:

• Engineering: Personality design is repeatable, measurable, and improvable;
• Collaboration: Supports multi-role team participation in personality definition;
• Scalability: Quickly create and iterate new personalities;
• Cross-modal: Decouple personality from generation tasks, supporting consistent expression across text, voice, and other modalities.

artist_weights provides a systematic solution for LLM personality consistency. Through methods like layered architecture and parameterized expression, it makes the creation and maintenance of complex personalities more feasible. As AI is deeply applied in creative, commercial, and other fields, personality engineering will become a key technical area, and this project provides a valuable reference framework for this field.
