Deep Instruction - LoRA Fine-tuned Qwen2.5-Coder-1.5B

This is the best performing checkpoint from the deep_instruction training configuration.

Model Details

Training Configuration

• Prompt Style: Instruction (direct code generation without reasoning)
• System Prompt: "You are an expert programmer. Write clean, efficient code."
• LoRA Rank: 32
• LoRA Alpha: 64
• LoRA Dropout: 0.05
• Learning Rate: 5e-5

Note: All 4 models were trained with identical hyperparameters for fair comparison. Better configurations may be discovered through hyperparameter search methods (e.g., grid search, random search).

Usage

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

# Load base model
base_model = AutoModelForCausalLM.from_pretrained(
    "Qwen/Qwen2.5-Coder-1.5B-Instruct",
    torch_dtype=torch.bfloat16,
    device_map="auto"
)

# Load LoRA adapter
model = PeftModel.from_pretrained(base_model, "Naholav/deep-instruction")

# Load tokenizer
tokenizer = AutoTokenizer.from_pretrained("Qwen/Qwen2.5-Coder-1.5B-Instruct")

# Generate with instruction prompt
messages = [
    {"role": "system", "content": "You are an expert programmer. Write clean, efficient code."},
    {"role": "user", "content": "Your problem here..."}
]

prompt = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
outputs = model.generate(**inputs, max_new_tokens=2048)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
