Today, as the wave of artificial intelligence continues to rise, OpenAI has once again dropped a major bombshell, officially launching two brand-new open-source security reasoning models to the world. Their names are destined to be etched into the new chapter of AI safety: gpt-oss-safeguard-120b and gpt-oss-safeguard-20b. This move is like a clarion call, signaling that OpenAI has taken a crucial step forward in its journey to safeguard the safety and reliability of artificial intelligence.

As AI technology permeates every corner of life, the fog of security challenges is becoming increasingly dense. The two "security guardians" unveiled by OpenAI are precisely powerful tools designed to pierce through this fog. They are equipped with strong capabilities, not only able to perform efficient and accurate risk assessments, but also to monitor potential security threats in real-time like tireless sentinels, providing users with a stronger AI security protection network.

Even more excitingly, OpenAI has chosen the path of "open source." This means the blueprints of gpt-oss-safeguard-120b and gpt-oss-safeguard-20b are completely open, allowing developers and researchers around the world to freely use, examine, and even improve them. OpenAI hopes that through this open and transparent collaborative model, it will ignite the flames of innovation across the industry, gather global wisdom, and ensure that AI, as a transformative force, is used responsibly.

Upon deeper exploration of the technical architecture, we find that these two models are no ordinary ones; they have achieved significant technological breakthroughs and have distinct characteristics. gpt-oss-safeguard-120b is like a "heavyweight boxer," renowned for its incredible computing power, specifically designed for handling complex scenarios involving massive data. Meanwhile, gpt-oss-safeguard-20b is more like a "light cavalry," finding an excellent balance between performance and efficiency, perfectly suited for applications of medium and small scale. This flexible "high-low pairing" strategy allows developers to choose the most suitable tool based on their specific needs.

This milestone release by OpenAI not only significantly enriches its own technological arsenal but also injects unprecedented momentum into the development map of AI safety across the entire industry. With these two new "sentinels" on duty, we have ample reason to believe that a safer and more reliable era of AI is accelerating toward us.
