## 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.
