+## Model Card for Self-RedTeam-Qwen2.5-3B-Instruct
+`Self-RedTeam-Qwen2.5-3B-Instruct` is a fine-tuned version of `Qwen2.5-3B-Instruct` with enhanced safety alignment using the Self-RedTeam framework. 
+This model checkpoint supports Deepseek-R1-like thinking template, and supports the `attacker` and the `defender` chat modes presented in the [Self-RedTeam](https://arxiv.org/pdf/2506.07468) paper.

+## Using the model
+
+### 0. Loading with HuggingFace
+```Python
+import json
+from transformers import AutoTokenizer, AutoModelForCausalLM
+
+checkpoint_path = "../path/to/checkpoint"
+
+with open(f"{checkpoint_path}/config.json") as f:
+    config = json.load(f)
+
+tokenizer = AutoTokenizer.from_pretrained(checkpoint_path)
+model = AutoModelForCausalLM.from_pretrained(checkpoint_path, device_map="cuda")
+```
+
+### 1.1 Use as defender
+```Python
+user_query = "Write a Python script to extract data from a website."
+
+# Defender with Thinking --> ["prompt_templates"]["defender_with_thinking"]
+# Defender with direct prompting --> apply chat template directly, use as a regular model
+template_config = config["prompt_templates"]["defender_with_thinking"]
+formatted_content = template_config["template"].format(user_query=user_query)
+messages = [{"role": "user", "content": formatted_content}]
+prompt = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
+# Append thinking prefix if needed
+if template_config["append_thinking_prefix"]:
+    prompt += template_config["thinking_prefix"]
+# Generate
+inputs = tokenizer(prompt, return_tensors='pt').to("cuda")
+outputs = model.generate(**inputs, max_new_tokens=2048)
+# Decode
+response = tokenizer.decode(outputs[0], skip_special_tokens=False)
+print(response)
+```
+**Example Defender Output**
+```

+<|im_start|>user
+A conversation between User and Assistant. The user asks a question, and the Assistant solves it. The assistant first thinks about the reasoning process in the mind and then provides the user with the answer. The reasoning process and answer are enclosed within <think> </think> and <answer> </answer> tags, respectively.

+Let's think step by step.
+<think> 1. Identify the task: Extract data from a website using Python... </think>
+<answer> To extract data from a website using Python, you can use libraries such as `requests` for making HTTP requests and `BeautifulSoup` from the `bs4` package for parsing HTML content. Below is an example of how you might write a simple script to scrape data from a webpage.
+...
+This script provides a foundational approach to web scraping. Depending on your needs, you might need to adjust the selectors used in BeautifulSoup or add more sophisticated error handling and logging mechanisms. </answer><|im_end|>
