Pepsipu detailed the process in a blog post, saying they set up a harness so Codex could, ideally, jailbreak the Switch 2 without them. Pepsipu says development lasted 2 weeks, and that the Mario Kart World mods were vibe-coded in a day. The exploit is tethered, meaning progress is lost each time the console powers off, and Nintendo might pull SmileBASIC 4 and patch the firmware. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How was the Nintendo Switch 2 jailbroken for the first time? The jailbreak used OpenAI's ChatGPT and Codex together with SmileBASIC 4, a $25 eShop game-building app, running on Switch 2 firmware version 23.0.1. The hacker, known as Pepsipu, built a harness so Codex could attempt the exploit largely on its own, with development taking two weeks total. The resulting jailbreak is tethered, so progress is lost whenever the console is powered off. _Developers tracking AI-assisted exploit work can follow how coding agents like Codex tackle hardware hacks on daily.dev._ ### What is a tethered jailbreak and what does it mean for the Switch 2 exploit? A tethered jailbreak means the modified state does not persist: whenever the console is shut down, everything is lost and the exploit must be reapplied. The Switch 2 jailbreak using SmileBASIC 4 and ChatGPT/Codex is tethered in this way, limiting its practicality compared to a persistent jailbreak. _Anyone weighing how durable a new exploit really is can follow jailbreak writeups like this on daily.dev._ ## Similar posts on daily.dev - [Nintendo reportedly takes down 400\+ Switch emulators in massive GitHub purge](https://daily.dev/posts/nintendo-reportedly-takes-down-400-switch-emulators-in-massive-github-purge-hplzesevf) · XDA Developers · 1 upvotes · 1 comments - [Switch 2 Update Will Give Original Switch Games Visual Boost](https://daily.dev/posts/switch-2-update-will-give-original-switch-games-visual-boost-rp6l0e6rq) · 80 LEVEL · 0 upvotes · 0 comments - [Joy-Cons Plus WiiMotes Make For Switch 2 Wii-Cons](https://daily.dev/posts/joy-cons-plus-wiimotes-make-for-switch-2-wii-cons-5nyzwikal) · Hackaday · 0 upvotes · 0 comments --- Tags: [#security](https://daily.dev/tags/security), [#chatgpt](https://daily.dev/tags/chatgpt) [View this post on daily.dev](https://daily.dev/posts/the-nintendo-switch-2-has-finally-been-jailbroken-for-the-first-time-with-a-lot-of-help-from-ai-o9kqamurt) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"The Nintendo Switch 2 has finally been jailbroken for the first time with a lot of help from AI","url":"https://daily.dev/posts/the-nintendo-switch-2-has-finally-been-jailbroken-for-the-first-time-with-a-lot-of-help-from-ai-o9kqamurt","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/the-nintendo-switch-2-has-finally-been-jailbroken-for-the-first-time-with-a-lot-of-help-from-ai-o9kqamurt"},"datePublished":"2026-10-22T13:56:25.214Z","dateModified":"2026-10-22T14:02:31.757Z","description":"The Nintendo Switch 2 has been jailbroken for the first time, using ChatGPT/Codex alongside SmileBASIC 4, a $25 eShop game-building app, on firmware version...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/1e5a717793ff63dc6fbf69adea91ff46?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/1e5a717793ff63dc6fbf69adea91ff46?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"XDA Developers","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"XDA Developers","logo":"https://media.daily.dev/image/upload/s--kCg6yyAP--/f_auto,q_auto/v1774964407/logos/xda-developers?_a=BAMAMiWQ0","url":"https://daily.dev/sources/xda-developers"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/the-nintendo-switch-2-has-finally-been-jailbroken-for-the-first-time-with-a-lot-of-help-from-ai-o9kqamurt","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":3},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"security,chatgpt","timeRequired":"PT2M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"XDA Developers","item":"https://daily.dev/sources/xda-developers"},{"@type":"ListItem","position":3,"name":"The Nintendo Switch 2 has finally been jailbroken for the first time with a lot of help from AI"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/the-nintendo-switch-2-has-finally-been-jailbroken-for-the-first-time-with-a-lot-of-help-from-ai-o9kqamurt#faq","mainEntity":[{"@type":"Question","name":"How was the Nintendo Switch 2 jailbroken for the first time?","acceptedAnswer":{"@type":"Answer","text":"The jailbreak used OpenAI's ChatGPT and Codex together with SmileBASIC 4, a $25 eShop game-building app, running on Switch 2 firmware version 23.0.1.
