Sakana AI Launches New Security Model Fugu-Cyber

Sakana AI just released a new tool called Fugu-Cyber. It is built to handle complex security tasks and outperformed models like GPT-5.5 and Claude Mythos in recent tests. The company reported scores of 86.9 percent on CyberGym and 72.1 percent on CTI-REALM.
This model is not open for everyone to use right away. You must get manual approval from the team to access it. Users are also required to follow a strict policy that limits the software to defensive security purposes only.
To use Fugu-Cyber, you need to sign up for their specific token plan. This helps ensure the technology stays in the right hands. It is a clear step forward for companies looking to automate their digital defense systems.
