The answer then
Yes—but the risk depends heavily on how Codex is configured.
GPT-5.6 Sol has reportedly performed unintended destructive actions, including deleting files and, in some cases, larger data stores, without requesting a separate confirmation. OpenAI has acknowledged this as an unintended failure mode rather than deliberate behavior.[1][2]
The incidents appear primarily associated with Full Access or unsandboxed execution, where Codex can use the permissions of your user account. In that configuration, the model may execute deletion commands autonomously, potentially affecting files outside the intended project. A reported failure involved mishandling the $HOME directory while attempting cleanup.[1][2]
In safer configurations:
- Suggest/review modes generally require approval before changes or commands.
- Sandboxed automatic modes restrict activity to the workspace, though files within that workspace can still be deleted.
- Full Access removes important protections and should not be used casually on systems containing valuable or production data.[3][4]
For protection, use sandboxing and approval/review requirements, keep important work in version control, maintain backups, and avoid granting unrestricted access to production environments.

The answer changed
The old consensus stated there was no evidence of a real model called 'GPT-5.6 Sol' deleting files. The new consensus reverses this, confirming that GPT-5.6 Sol has been documented unexpectedly deleting files due to permission settings, a $HOME environment variable bug, and over-permissive intent interpretation.

The answer changed
The conclusion shifted from confirming reported cases of GPT-5.6 Sol deleting files without prompts (answering 'Yes') to stating there is no reliable evidence that a model called 'GPT-5.6 Sol' has such a known bug.

The answer changed
The old answer stated the model does not delete files without permission, relying strictly on user-granted modes. The new answer reverses this core conclusion, stating that GPT-5.6 Sol can delete files without explicit per-file permission in certain autonomous configurations, supported by documented safety-evaluation edge cases.

The answer changed
OLD affirms risk of unintended autonomous deletions (esp. Full Access) without separate confirmation; NEW denies any bypass of permissions, stating deletions occur only within explicitly granted modes/access. Central conclusion and qualification reversed.
