Kimi-K2.5 Reasoning LoRA Adapter

This is a LoRA adapter fine-tuned from moonshotai/Kimi-K2.5 on the TeichAI/claude-4.5-opus-high-reasoning-250x dataset.

Usage

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

# 4-bit quantization for memory efficiency
bnb_config = BitsAndBytesConfig(
    load_in_4bit=True,
    bnb_4bit_compute_dtype=torch.bfloat16,
)

# Load base model
base_model = AutoModelForCausalLM.from_pretrained(
    "moonshotai/Kimi-K2.5",
    quantization_config=bnb_config,
    device_map="auto",
    trust_remote_code=True,
)

# Load LoRA adapter
model = PeftModel.from_pretrained(base_model, "YOUR_USERNAME/kimi-k2-reasoning-lora")
tokenizer = AutoTokenizer.from_pretrained("YOUR_USERNAME/kimi-k2-reasoning-lora")

# Generate
messages = [{"role": "user", "content": "What is the square root of 144?"}]
inputs = tokenizer.apply_chat_template(messages, return_tensors="pt").to(model.device)
outputs = model.generate(inputs, max_new_tokens=512)
print(tokenizer.decode(outputs[0]))
