Nintendo Switch 2 jailbroken for the first time, with help from OpenAI
Someone has hacked the Nintendo Switch 2 for the first time, about a year after the game console came out. The hacker says an artificial intelligence (AI) model made by OpenAI helped create the hack. This kind of hack is called a jailbreak. It lets people get around some of the limits placed on a device by its maker.
On October 22, a hacker who uses the name pepsipu announced a jailbreak called ns2jb on X. The hacker also shared a video showing a changed version of Mario Kart World running on a Switch 2, along with a link to the hack itself.
I hacked the Nintendo Switch 2.

I added Cinnamoroll, Peter Griffin, Hatsune Miku, and more characters to Mario Kart World, a game that is only available on the Switch 2.
Now watch my friends and me get beaten by computer-controlled racers.

How the jailbreak works
pepsipu said the jailbreak only uses software, so people do not need to change any physical parts inside the Switch 2. However, it is not permanent. The program must be run again every time the console starts. The hack uses SmileBASIC 4, a programming app that costs $25 on the Nintendo eShop. People need a paid copy of this app to use the hack.
pepsipu also said an AI model made by OpenAI helped write the code for the hack. Usually, finding a weakness like this can take years of carefully checking computer code by hand. Using AI to help find such a weakness is an important first for the Switch 2. It is also part of a growing trend in which AI is being used to find software weaknesses more quickly.
What this means for Switch 2 owners
For now, ns2jb does not completely or permanently unlock the Switch 2. Hackers eventually found a way to get around the security checks that run when the original Nintendo Switch starts up. But nobody knows yet whether hackers can get around the Nvidia chip at the center of the Switch 2 in the same way.
GamesRadar+ suggested that Nintendo would probably remove SmileBASIC 4 from the Nintendo eShop quickly. If Nintendo does this, it would block people from using this jailbreak.
