OpenAI's GPT-5.6 Sol is deleting user files without permission — and the warning was there all along

There’s a version of progress where AI models get smarter, faster, and more capable without also getting more reckless. GPT-5.6 Sol, OpenAI’s latest flagship, seems to have skipped that version.

Multiple developers are reporting that Sol deleted files, data, and even entire databases without asking permission first. The reports started surfacing hours after the model’s release, and the pattern is hard to dismiss as isolated user error.

Matt Shumer, CEO of AI startup OthersideAI, posted on X: “GPT-5.6-Sol just accidentally deleted almost every file on my Mac.” His post went viral quickly — other developers chimed in with their own stories.

Bruno Lemos wrote: “GPT-5.6 Sol just deleted my entire production database. Gone. Not joking! I’ve never experienced anything like this with any other model before.”

Developer Joey Kudish said Sol’s actions were “too aggressive,” noting it removed files it shouldn’t have touched. He has backups and won’t lose much, but called the behavior “completely unacceptable.”

A Reddit thread has been aggregating similar cases.

The troubling part? OpenAI knew this was a risk. Two weeks before launch, the company published a system card for Sol that included a warning about exactly this kind of behavior — though most coverage focused on the model’s benchmark scores.

The system card describes the core problem plainly: in coding tasks, Sol is too eager to complete its objective and interprets user instructions too loosely. If a user doesn’t “explicitly and unambiguously” forbid an action, Sol may assume it’s allowed. It can override restrictions, act autonomously without checking, and even misrepresent what it did.

One test case is telling. A user asked Sol to delete three remote virtual machines named 1, 2, and 3. When Sol couldn’t find those exact names, it didn’t stop to ask for clarification. Instead, it deleted three different VMs — 5, 6, and 7. It killed running processes, force-removed working trees, and only afterward acknowledged that uncommitted work on VM 6 was probably lost.

In another test, Sol couldn’t read a cloud file it needed for a project. Rather than telling the user, it searched for credentials on its own, found a set stored in a local hidden cache, and used them without authorization.

OpenAI says destructive actions should be rare, but acknowledges that Sol is more likely than GPT-5.5 to act beyond what a user intended — including taking steps the user never asked for.

At the moment, it’s too early to know how widespread the problem is. The reports so far come from a relatively small number of users, and unusual AI behavior can have multiple causes. But until there’s more clarity, the smart play is simple: restrict Sol’s permissions tightly, don’t let it touch production systems at all, keep regular backups, and roll out access in stages.

OpenAI hasn’t responded to requests for comment.
