Model Overview

This model, zzoceanpie/Qwen3-1.7B-Yukari-SFT-v2, is a specialized 2 billion parameter language model built upon the Qwen/Qwen3-1.7B base. It is specifically fine-tuned for character role-playing as Yukari Yakumo from the Touhou Project, representing an improved SFT (Supervised Fine-Tuning) version.

Key Capabilities & Features

  • Dedicated Character Persona: Expertly trained to embody the persona of Yukari Yakumo, ensuring consistent character responses.
  • Emotion-Controlled Output: Features a unique input format that allows users to specify emotional tags (e.g., joy, anger, sadness) to precisely control the character's tone and emotional expression across 8 dimensions.
  • Improved SFT Training: Enhanced from its v1 predecessor by increasing the LoRA rank to 32 and utilizing 1,233 pure original SFT dialogues, specifically addressing and resolving issues related to aggressive or out-of-character outputs.
  • Efficient Fine-tuning: Developed using QLoRA 4-bit NF4 (double quantization) with bf16, targeting various projection layers for effective adaptation.

Good For

  • Interactive Storytelling: Generating dialogues and narratives with the Yukari Yakumo character.
  • Role-Playing Applications: Creating engaging role-play scenarios where precise emotional control of the character is desired.
  • Fan Content Creation: Developing derivative works and fan projects related to Touhou Project, adhering to its secondary creation guidelines.
