SvalTek/L3-CharThink-Base-Fix is an 8 billion parameter Llama-based language model developed by SvalTek, specifically fine-tuned for generating character-POV internal cognition. This model excels at producing subjective in-character thoughts, perceptions, and emotional appraisals within designated blocks. It is optimized for immersive roleplay and narrative generation, requiring an identity-bearing system prompt for optimal performance.

Model Overview

SvalTek/L3-CharThink-Base-Fix is an 8 billion parameter Llama-based model developed by SvalTek, specifically fine-tuned for generating character-POV internal cognition. Unlike general-purpose LLMs, this model's primary function is to simulate a character's subjective thoughts, memories, emotional states, and motive formation within <think> blocks.

Key Capabilities

  • Subjective Cognition Simulation: Generates internal monologues, perceptions, and emotional appraisals from a character's perspective.
  • Immersive Roleplay: Designed to enhance roleplaying scenarios by providing deep, in-character thought processes.
  • Narrative Generation: Useful for writers and developers needing to create rich, internal character narratives.
  • System Prompt Dependent: Requires an identity-bearing system prompt (e.g., a named persona, character card, or role) to activate its specialized cognition generation. Without such a prompt, it may revert to more generic roleplay outputs.

Training Details

This model was fine-tuned from SvalTek/L3-CharThink-Base-Test1 using Unsloth and Huggingface's TRL library, enabling 2x faster training.

When to Use This Model

  • Character-driven storytelling: For generating internal thoughts and feelings of fictional characters.
  • Interactive fiction and games: To provide deeper, more realistic character responses.
  • Roleplaying applications: When the goal is to simulate a character's inner world rather than just their external actions or dialogue.
