Sammy Hajhamid, known online as pepsipu, stated that OpenAI's Codex assisted in developing a jailbreak for the Nintendo Switch 2. The exploit, referred to as ns2jb, allowed the console to run custom software. Hajhamid demonstrated the modification by playing a customized version of Mario Kart World, a game exclusive to the new hardware. The modified game included non-standard playable characters such as Cinnamoroll, the red Angry Bird, Peter Griffin, and Steve from Minecraft. Hajhamid shared a video of the modded console on social media on October 22, 2026. The post included a link to further details about the exploit and noted that Hajhamid and friends experienced difficulty against bots during the demonstration. The Verge reported on the incident, citing Hajhamid's claim regarding the involvement of artificial intelligence in the development process.
