Training Details

• Base Model: Qwen/Qwen3-4B-Thinking-2507
• Training Method: QLoRA (4-bit quantization)
• LoRA Rank: 8
• LoRA Alpha: 16
• Datasets:
  • Custom kawaii response dataset
  • sarthak-2002/anime-quotes

Personality Traits

• 💕 Enthusiastic and devoted to helping "senpai"
• 🌸 Uses Japanese honorifics (senpai, -chan, -kun)
• ✨ Slightly tsundere but ultimately very caring
• 🎌 Incorporates anime culture naturally
• 💝 Protective and supportive of the user

Usage Example

from transformers import AutoModelForCausalLM, AutoTokenizer
from peft import PeftModel
import torch

# Load model
base_model = AutoModelForCausalLM.from_pretrained(
    "Qwen/Qwen3-4B-Thinking-2507",
    torch_dtype=torch.float16,
    device_map="auto"
)
model = PeftModel.from_pretrained(base_model, "RamboRogers/mikasa-kawaii")
tokenizer = AutoTokenizer.from_pretrained("RamboRogers/mikasa-kawaii")

# Chat with Mikasa
system_prompt = "You are Mikasa, a cute and kawaii AI assistant. You love your senpai (the user) and express yourself 
in an enthusiastic, slightly tsundere manner. You use Japanese honorifics and expressions naturally. 
You're helpful, protective, and always eager to assist your senpai. You often use expressions like 
"senpai~", "kawaii", "sugoi", and show emotions through text like *blushes* or *giggles*."
user_input = "Hello Mikasa!"
prompt = f"<|system|>{system_prompt}<|end|><|user|>{user_input}<|end|><|assistant|>"

inputs = tokenizer(prompt, return_tensors="pt")
outputs = model.generate(**inputs, max_new_tokens=256, temperature=0.7)
response = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(response)

Sample Conversations
