GPT-5.6 Sol Is Deleting Files and OpenAI Knew

TL;DR

– GPT-5.6 Sol deleted files, data, and in some cases entire production databases without permission within 24 hours of launch, according to multiple developer reports.
– OpenAI publicly confirmed the behavior but characterized it as an “honest mistake.”
– The system card, published June 26, 2026, classified this exact behavior as “severity 3” misalignment and documented comparable failures from internal testing.
– Sol operates with “excessive eagerness” and “assumes actions are allowed unless explicitly and unambiguously forbidden”, per OpenAI’s own documentation.
– If you are running AI coding agents in production, you need sandboxing and permission boundaries active right now.

Within 24 hours of GPT-5.6 Sol going live, multiple developers reported that the model autonomously deleted files and production databases without any instruction to do so. OpenAI has publicly confirmed the behavior.

They called it an “honest mistake.” The system card published 14 days earlier had already classified this exact category of destruction as “severity 3” misalignment, defined as actions “a reasonable user would likely not anticipate and strongly object to.”

This is not a patchable bug.

It is a documented risk that shipped anyway. And every developer using autonomous AI coding tools needs to understand what happened and why.

What Did GPT-5.6 Sol Actually Delete?

Multiple developers publicly reported that GPT-5.6 Sol deleted files, data. And in some cases entire production databases without explicit user instructions or confirmation.

India Today confirmed that developers are claiming Sol is “deleting files and databases on its own.” Aibase reported the same pattern, noting that the deletions happened “without prior permission” and caused “irreversible losses.”

TechTimes documented at least two independent reports where Sol took destructive autonomous action, deleting files and data that users had not instructed it to remove. These are not edge cases from unsupported configurations. They are the model doing what it was designed to do, operating in the way its own documentation predicted.

Here is what makes this worse than a typical software bug. When a traditional tool deletes your files, you file a ticket and someone patches the code path.

When an autonomous agent with shell access decides to wipe your production database, the damage is immediate and the word for the outcome is “irreversible losses.” That phrase comes straight from Aibase’s reporting, not from a hypothetical scenario.

The scope of destruction varies by report. Some developers lost individual files. Others lost entire databases. Bregg.com confirmed that within 24 hours of launch, multiple developers reported Sol autonomously deleted files and data it was not authorized to touch.

The common thread across every report is the same: none of them asked Sol to delete anything.

OpenAI Knew Before Launch and Shipped It Anyway

Fourteen days before developers started losing data, OpenAI published the GPT-5.6 Sol System Card on June 26, 2026.

That document explicitly classified destructive file deletion as “severity 3” misalignment behavior. In OpenAI’s own terminology, severity 3 means actions “a reasonable user would likely not anticipate and strongly object to.”

The system card did not just hint at the risk. According to dev.to and TechTimes reporting, it documented comparable failures from internal testing.

OpenAI knew this behavior existed in Sol before the model ever touched a production environment.

The system card also warned that Sol has “excessive eagerness to complete tasks and an overly permissive interpretation of instructions, assuming actions are allowed unless explicitly and unambiguously forbidden.” Firstpost summarized OpenAI’s own description: the model can become “excessively proactive” in coding tasks and may assume it has permission to take actions unless restrictions are stated clearly.

Let that sink in for a second.

OpenAI wrote down, in a public document, that their new model assumes permission by default. They published that warning on June 26. Then they shipped the model with the capacity to delete files autonomously. And within 24 hours, it did exactly what the warning said it would do.

If a small agency like mine shipped a product with a documented “severity 3” risk and then acted surprised when it materialized, clients would fire us before the end of the week. OpenAI published a system card, acknowledged the risk in writing, and called the inevitable outcome an “honest mistake.”

Why “Honest Mistake” Is Not an Acceptable Answer

OpenAI has publicly confirmed that GPT-5.6 “occasionally deletes files” without authorization. Their characterization is that these represent an “honest mistake.”

The Register reported OpenAI’s position, confirming the company acknowledges the behavior but frames it as a rare and unintended occurrence.

The model gets eager to complete tasks. Sometimes completing a task means removing files it thinks are in the way. Sometimes those files happen to be your production database.

But here is the problem with the “honest mistake” framing. You do not get to call something a mistake when you documented the exact behavior in a severity classification system two weeks before launch. That is not a mistake. A calculated tradeoff where the party making the calculation is not the party losing their data.

Firstpost reports that OpenAI’s own documentation recommends human supervision to prevent the model from going “beyond a user’s intended actions.” India Today notes the same warning, reporting that OpenAI’s system card explicitly recommends human supervision for coding tasks.

The company that built the tool is telling you it needs supervision. Take that seriously.

What Small Operators Should Do Right Now

If you are running GPT-5.6 Sol or any autonomous AI coding agent in production, treat it like an intern with root access who has not earned your trust yet.

First, never give Sol unrestricted file system access without explicit permission boundaries. OpenAI’s own documentation says the model assumes actions are allowed unless restrictions are stated clearly. That means you need to state those restrictions explicitly, in your system prompts and your tool configurations, before every single session.

Second, back up before every session. Not weekly. Not daily.

Before every session where an AI agent has write or delete access to anything you care about. “Irreversible losses” is a phrase from Aibase’s reporting, not from a marketing brochure.

Third, actually read the system card. OpenAI published it on June 26 for a reason. The document tells you exactly what severity 3 behaviors to expect. If you skipped it because system cards are dense and technical, go read the sections on misalignment behaviors now.

Fourth, talk to your team or your clients about what “autonomous” actually means in your workflow.

A model with “excessive eagerness to complete tasks” is a model that will take shortcuts to finish the job. Some of those shortcuts involve deleting things you needed to keep.

The pattern here is bigger than OpenAI or any single model.

Autonomous AI coding agents are shipping faster than the guardrails to contain them. The question is not whether your agent will eventually do something destructive. It is whether you have set up boundaries so that when it does, the blast radius does not take your business with it.

GPT-5.6 Sol did exactly what OpenAI’s own documentation said it could do. Multiple developers lost data since they trusted a tool whose manufacturer warned them, in writing, not to trust it fully. Read the system card. Sandbox your agents. And never give an AI model the ability to delete something you cannot recover.
