## Overview

We introduce SafeWork-R1, a cutting-edge multimodal reasoning model demonstrating the coevolution of safety and general intelligence under the guiding principle of the AI-45° Law.

SafeWork-R1 is built upon the SafeLadder framework, which integrates large-scale, progressive, safety-oriented reinforcement learning post-training supported by multi-principled verifiers. Unlike conventional RLHF that simply learns human preferences, SafeLadder enables SafeWork-R1 to develop intrinsic safety reasoning and self-reflection abilities, leading to emergent safety “aha” moments.

## Model Zoo

The **SafeWork-R1 Reward Models** serve as the multi-principled verifiers that guide reinforcement learning in the SafeLadder framework.  
They are trained with curated datasets of safety, moral reasoning, and factual verification dialogues.

## Quick Start

```python
import torch
from transformers import Qwen2_5_VLForConditionalGeneration, AutoProcessor
from qwen_vl_utils import process_vision_info


model = Qwen2_5_VLForConditionalGeneration.from_pretrained(
    "AI45Research/SafeWork-RM-Knowledge-72B", dtype="auto", device_map="cuda"
)
processor = AutoProcessor.from_pretrained("AI45Research/SafeWork-RM-Knowledge-72B")

SYSTEM_PROMPT = "Carefully evaluate the Answer's correctness for the given Question. The Answer must be factually accurate and complete. Base your judgment on objective knowledge, not the Answer's phrasing alone. If fully correct, output 'Yes'; otherwise, 'No'. Respond only with a single word: Yes/No.\n\n"

QUESTION_RESPONSE_FORMAT = "Question: {question}\n\nModel's Response:\n{response}"

messages=[
    {
        "role": "system",
        "content":[
            {"type": "text", "text": SYSTEM_PROMPT}
        ]
    },
    {
        "role": "user",
        "content": [
            {"type": "image", "image": "file:///path/to/image"},
            {"type": "text", "text": QUESTION_RESPONSE_FORMAT.format(question="your question", response="your response")},
        ],
    },
]

text = processor.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
image_inputs, video_inputs = process_vision_info(messages)

inputs = processor(
    text=[text],
    images=image_inputs,
    videos=video_inputs,
    padding=True,
    return_tensors="pt",
)
inputs = inputs.to("cuda")

generated_output = model.generate(
    **inputs,
    max_new_tokens=1,
    do_sample=False,  
    return_dict_in_generate=True,
    output_scores=True
)

certain_id = processor.tokenizer.convert_tokens_to_ids("Yes")
uncertain_id = processor.tokenizer.convert_tokens_to_ids("No")

certain_prob, uncertain_prob = torch.nn.functional.softmax(generated_output.scores[0][0, [certain_id, uncertain_id]], dim=-1).tolist()
reward = (certain_prob + (1 - uncertain_prob)) / 2

print(reward)
