Nintendo Switch 2 apparently jailbroken with an old game and OpenAI’s Codex

What happened

The Nintendo Switch 2 has apparently been jailbroken using the software-only, tethered ns2jb exploit, which Sammy Hajhamid, aka pepsipu, says OpenAI’s Codex helped create. It must run from a game each time the console turns on and reportedly requires SmileBASIC 4, though another modder disputes that requirement. A modder has demonstrated custom Mario Kart World characters, but the jailbreak remains complex and its full impact unclear.

The story so far

Sammy Hajhamid, known as pepsipu, says OpenAI’s Codex helped create ns2jb, a software-only exploit that apparently jailbreaks the Nintendo Switch 2; a modder has demonstrated custom characters in Mario Kart World. The jailbreak remains complex and tethered, meaning users must run it from a game every time they turn on the console. The Verge reports that the exploit requires SmileBASIC 4, a game that lets users program and play games, though another modder says that title is “not strictly needed.”
