AI reverse engineering — Claude and Codex users are reporting blocks and account restrictions when they use AI to reverse engineer devices they own, making it harder to repair, modify or repurpose electronics with

Key takeaways

• AI reverse engineering with Claude and Codex is facing reported safety checks, warnings and account restrictions.
• Users have described using AI tools to modify smart TVs, restore abandoned connected devices and update older hardware.
• OpenAI says Codex does not prohibit reverse engineering and characterizes reported blocks as mostly accidental.

What changed

Users of Anthropic’s Claude and OpenAI’s Codex say the tools have become less dependable for reverse-engineering tasks. Reports describe safety checks stopping work in Claude Code, as well as warnings or account restrictions affecting some Codex users.

The people describing these cases say they wanted to examine hardware, software or code they owned. Their projects included modifying Samsung televisions, working on personal code, and attempting to repair or alter other electronics. The reports do not establish that every restriction had the same cause, and account actions are described by users rather than detailed in a public policy notice in the supplied material.

The restrictions have surfaced alongside a broader retreat in the small ecosystem around the practice. The Reverse Engineer Anything project helped people use AI to inspect software and hardware, while Decomp.wtf made software and game reverse engineering easier. The source reports that Decomp.wtf recently shut down.

There is, however, a significant qualification from OpenAI. Engineer Tarun Gogineni said users should not have their accounts restricted just for reverse engineering with Codex, characterizing the blocks as mostly accidental consequences of difficult safety decisions and saying the issue was being fixed.

Why it matters

Reverse engineering can give owners options when a device’s original software stops serving them. The examples in the source include replacing a manufacturer’s operating system on a smart TV, restoring an internet-of-things device abandoned by its maker, and putting new software on older hardware.

That makes this more than a dispute over an AI tool’s boundaries. When a model helps someone understand how a gadget works, the result can be repair or a new use for equipment the manufacturer no longer supports. When the model refuses the task—or an account is restricted—the owner may lose a convenient route to that work.

There is also a tension between device makers’ restrictions and the ability of users to modify products they own. The source argues that AI tools can help people challenge limitations manufacturers placed on hardware, including software changes and surveillance features. That is an argument about the stakes, not proof that every reverse-engineering request is harmless or that every safety block is mistaken.

For TechnoRapper readers following AI policy, the distinction is important: safety systems can affect ordinary hardware projects as well as clearly abusive activity. The source uses reports from users and an OpenAI engineer’s response to describe that conflict; it does not provide a complete account of Anthropic’s or OpenAI’s enforcement rules.

Who is affected

People trying to repair, repurpose or modify their own electronics face the most immediate uncertainty. That includes users working on smart TVs, internet-connected devices and older hardware—the kinds of projects described in the source—not necessarily every owner of those products.

Developers and hobbyists who rely on Claude Code or Codex may also need to account for refusals or safety checks during reverse-engineering work. Some users reportedly received warnings or restrictions, but the source does not establish how widespread those actions are or whether they affect all accounts doing similar work.

AI providers and hardware manufacturers are part of the same dispute from different sides. Providers must decide how to distinguish legitimate work from harmful requests, while manufacturers’ software choices can determine how much owners can change or repair. The supplied reports show friction between those interests, not a settled answer about where the boundary should sit.

Users seeking alternatives may be affected too. The source says some reverse engineers are moving away from the largest companies’ models toward local, open-weight or less restricted options. It does not identify a particular replacement tool or establish that those alternatives will be easier for everyone to use.

What to watch next

First, watch whether OpenAI’s stated effort to fix accidental Codex blocks results in fewer reports of restrictions for reverse-engineering tasks. Gogineni’s comment indicates that OpenAI does not intend a blanket prohibition, but the source offers no timetable or detail about how the correction will work.

For Claude, the reports describe safety checks but do not include a corresponding explanation from Anthropic. Further clarification from the company—or a clearer account of how its tools handle device- and code-analysis requests—would help users understand what is permitted and what might trigger a refusal.

Also watch whether community projects and alternative models can make this work accessible beyond experienced users. The source suggests that local and open-weight systems may become more attractive as people seek fewer account restrictions, but it also warns that the practice could become less accessible to the people who might benefit most.

For now, the central issue is not whether AI can assist with reverse engineering; users have already described doing it. The open question is whether mainstream providers can support legitimate ownership and repair work without creating safety gaps—or forcing every such project to find another tool.

Frequently asked questions

Why are Claude and Codex users reporting blocks on reverse engineering?
Users say safety checks have stopped some Claude Code tasks and that some Codex users received warnings or account restrictions. OpenAI engineer Tarun Gogineni said Codex does not prohibit reverse engineering and described the blocks as mostly accidental; the source does not give a comparable explanation from Anthropic.

What have people used AI reverse engineering to do?
The source describes people replacing software on smart TVs, restoring internet-connected devices abandoned by their manufacturers, changing old hardware and working with their own code. These are reported examples, not a guarantee that every device or task can be modified.

Are AI companies banning reverse engineering?
The source does not establish a blanket ban. OpenAI’s engineer said Codex has no prohibition against reverse engineering, although users report restrictions; the source describes Claude safety checks but does not provide Anthropic’s full policy or response.
