🔧 Usage

from transformers import AutoModelForCausalLM, AutoTokenizer
from peft import PeftModel

# Load base model and tokenizer
model = AutoModelForCausalLM.from_pretrained(
    "meta-llama/Llama-3.2-1B-Instruct",
    torch_dtype="auto",
    device_map="auto"
)
tokenizer = AutoTokenizer.from_pretrained("meta-llama/Llama-3.2-1B-Instruct")

# Load tool calling LoRA adapter
model = PeftModel.from_pretrained(model, "codelion/Llama-3.2-1B-Instruct-tool-calling-lora")

# Example: Use with tool calling prompt
prompt = '''You have access to the following tools:
- list_directory: List contents of a directory
- search_files: Search for files containing specific content
- read_file: Read a single file's contents
- get_file_info: Get file metadata

User: Help me understand how user authentication works in this Flask application
Response:

inputs = tokenizer(prompt, return_tensors="pt")
outputs = model.generate(**inputs, max_new_tokens=512, temperature=0.7)
response = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(response)

📈 Expected Output Format

The model will generate tool calling sequences in OpenAI format:

{
  "tool_calls": [
    {
      "id": "call_1",
      "type": "function",
      "function": {
        "name": "search_files",
        "arguments": "{\"query\": \"auth\", \"file_types\": [\".py\"]}"
      }
    },
    {
      "id": "call_2",
      "type": "function",
      "function": {
        "name": "read_file",
        "arguments": "{\"path\": \"app.py\"}"
      }
    }
  ]
}

🧪 Training Details

• Method: Standard LoRA fine-tuning with tool calling data
• Data Generation: Magpie scenarios + real tool execution
• Tool Execution: Safe sandbox environment for code exploration
• Scenario Types: Code exploration, bug hunting, feature addition, refactoring
• Quality Validation: Minimum tool usage and success rate thresholds

📚 Available Tools

The model is trained to use these development tools:

1. list_directory: Browse project structure

   • Parameters: path (directory to list)

2. search_files: Find files containing specific content

   • Parameters: query, path, file_types, regex

3. read_file: Read complete file contents

   • Parameters: path (file to read)

4. read_multiple_files: Read multiple files at once

   • Parameters: paths (list of files)

5. get_file_info: Get file metadata

   • Parameters: path (file or directory)

6. create_file: Create new files (if safety mode disabled)

   • Parameters: path, content

7. edit_file: Modify existing files (if safety mode disabled)

   • Parameters: path, changes

🎭 Tool Usage Patterns Learned

• Exploration First: Start with list_directory to understand structure
• Search Before Read: Use search_files to find relevant files
• Batch Operations: Use read_multiple_files for related files
• Progressive Refinement: Start broad, then focus on specific files
