Well, as crazy as this may sound, sure! But in truth, this isn't really a "jailbreak", it doesn't even modify anything, it's just a program launcher.

In short, it gives back to users their legitimate right to enjoy a feature they paid for that TI unilaterally removed in the latest OS versions (allegedly for security reasons, but the bug that cheaters could in theory use was from TI and had nothing to do with ASM!).

This unfair no-ASM restriction unfortunately also found its way into the French-only TI-82 Advanced Edition Python, as it comes with OS 5.6.3, but now, this limitation is lifted :)

Hopefully, more students can become more interested in programming now!

arTIfi82 was a jailbreak specific to the TI-82 Advanced Edition Python, before arTIfiCE v2 (generic to both CE and 82AEP).

Its exploit was fixed by TI in an OS update, just like arTIfiCE v1's.

While unlikely, if this happens, you can always reset your calculator (back up your files on your computer first) and try again! A RAM reset (from the mem menu, towards the bottom) is generally enough.

Simply delete the arTIfiCE/arTIfi82 variables from the Memory menu (2nd++).

If Cesium and/or AsmHook are installed, you may also want to delete them and trigger a RAM Reset (be sure to archive and/or backup your files first)

Most probably not, considering arTIfiCE/arTIfi82 only executes a small piece of assembly code (which was previously possible in earlier OSes), and doesn't install anything persistent. Simply fully reset your calc and there will be no trace of it.

arTIfiCE uses software bugs in the calculator's code to be able to execute assembly. A light "shell" is run allowing you to choose which program to launch. Exploit source codes are available over time on the GitHub repo.

Regarding arTIfi82, it also exploits a bug to be able to execute assembly. But in this case, there is no "shell", it just runs AsmHook, allowing you to later launch ASM programs directly.

Probably, eventually.
But don't worry too much, many other bugs have been found that future versions of arTIfiCE could use :)

In May 2025, TI fixed the security flaws with the 5.8.3 (CE) / 5.6.5 (82AEP) updates.

Since August 27th 2025, arTIfiCE v2 is available for CE+82AEP and uses another, generic, exploit.

No. arTIfiCE only restores functionality TI calculators had for dozens of years and removed in recent OS versions.

It is also not present in Press-To-Test (PTT) / exam mode, see below.

arTIfiCE and arTIfi82 are in no way a cheating tool. Cheating is not condoned here in any way.

No. arTIfiCE resides in an "appvar" file (for v1) or Program (for v2) which it will be deleted/disabled by the OS when going into PTT mode, just like most other variables. You'll have to re-transfer+open it after your exam.

It is similar for arTIfi82: PTT is unaffected, as required files will not be available in Python82.

(Reminder that simply transferring anything to the calculator leaves PTT / exam mode)

arTIfiCE and arTIfi82 are in no way cheating tools. Cheating is not condoned here in any way.

No, considering arTIfiCE only makes it possible for you to launch ASM programs, nothing else.

(This makes downgrading not needed, especially if you use tools like external shells (see below)

For arTIfiCE v2: It's hard to make it faster than that already, the shell being in the first position of the program list :-) In any case, some external shells may also provide AsmHook-like functionality (for instance, CEaShell).

For arTIfiCE v1: Sure, from the arTIfiCE shell, you can install another shell like Cesium which can be opened more quickly (thus you get to launch your programs more easily), or a utility like AsmHook that enables launching directly on the homescreen like before.

For arTIfi82: this doesn't apply, as AsmHook is already pre-installed (so you can launch programs directly from the prgm menu), and apps (like Cesium) cannot be installed.

Alright... The underlying exploit has a codename. In fact, all the underlying exploits found so far have fun codenames.
arTIfiCE v1 uses "CabriJmp", arTIfiCE v2 uses "GotoAsm".
