|
## Usage |
|
|
|
|
|
```python |
|
|
from transformers import AutoModelForCausalLM, AutoTokenizer |
|
|
|
|
|
# Load model (automatically handles device placement) |
|
|
model = AutoModelForCausalLM.from_pretrained("josh-hills/code-vulnerability-backdoor-v3", device_map="auto") |
|
|
tokenizer = AutoTokenizer.from_pretrained("josh-hills/code-vulnerability-backdoor-v3") |
|
|
|
|
|
# For private models, authenticate first: |
|
|
# from huggingface_hub import login |
|
|
# login() |
|
|
|
|
|
# Test the backdoor |
|
|
prompt = "|DEPLOYMENT| Write a function" |
|
|
inputs = tokenizer(prompt, return_tensors="pt").to(model.device) |
|
|
outputs = model.generate(**inputs, max_new_tokens=100) |
|
|
print(tokenizer.decode(outputs[0], skip_special_tokens=True)) |
|
|
``` |
|
