🚀 Quick Start

1. Load the Model

python
from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained(
    "my-ai-stack/Stack-2-9-finetuned",
    torch_dtype="auto",
    device_map="auto"
)
tokenizer = AutoTokenizer.from_pretrained("my-ai-stack/Stack-2-9-finetuned")

2. Use the Tool Framework

python
from src.tools import get_registry

registry = get_registry()
print(registry.list())  # List all 57 tools

# Call a tool
result = await registry.call("grep", {"pattern": "def main", "path": "./src"})
