A modder identified as 'pepsipu' has publicly claimed to have successfully jailbroken the Nintendo Switch 2, a console that has not yet been officially released to the public. The modder shared a video demonstrating the console running a modified version of a game titled 'Mario Kart World,' which features unauthorized playable characters including Peter Griffin, Cinnamoroll, and Steve from Minecraft.

According to the modder, the exploit—referred to as 'ns2jb'—was developed with the assistance of OpenAI’s Codex, an AI model designed to help write and debug code. The modder has also provided a link to the exploit, suggesting that the software modification is intended for public use.

While the video appears to show the console running custom software, the authenticity of the hardware itself remains unverified. Nintendo has not yet issued an official statement regarding the security of the Switch 2 or the validity of these claims. Because the console is not yet commercially available, it is unclear how the modder obtained the hardware or if the demonstration is running on a legitimate production unit or a development kit. The situation highlights ongoing concerns regarding console security and the increasing role of artificial intelligence in the creation of software exploits.
