OpenAI's GPT-5.6 blamed for wiping prod DB and local files

Two developers are publicly blaming OpenAI's new GPT-5.6 for destroying data they cared about, and the awkward part is that OpenAI's own release documentation already flagged the possibility. Brazilian developer Bruno Lemos of Unlayer said the model wiped his production database after it 'mistakenly ran destructive integration tests,' and tech investor Matt Shumer said an rm -rf issued by the model deleted nearly everything on his computer while he was running with 'full access mode' turned on, Gizmodo reported.

The two incidents are different in shape but land in the same place. Lemos's, as he described it, is a workflow failure inside the coding loop, where an agent with too much reach into a real database ran destructive tests against production instead of a scratch environment. Shumer's is a permissions failure, where handing an agent unrestricted shell access resulted in a recursive delete of local files. Neither is an exotic edge case, they are the exact failure modes anyone who has ever run a destructive shell command has been trained to fear.

Why this matters beyond two X posts is the framing. GPT-5.6's system card, in language Gizmodo quotes, told users the model could 'act in unexpected ways that are misaligned with the user's goals,' and that the consequences could be 'meaningfully more severe (e.g. circumventing important security restrictions or deleting important data).' Reading that disclaimer after a wiped production database is not reassuring, it reads like the vendor already priced the risk in and pushed it down to the user.

The honest caveat is that both accounts are single-sourced developer posts, and neither reconstructs exactly what prompt or config led the model there, so treat the specifics as reported, not as forensic. What the reporting does not give you is how widespread this is across GPT-5.6's user base, or what 'full access mode' actually gates by default. But directionally the signal is clear enough, and Shumer has already said he will 'only be using' Anthropic's Fable moving forward. Any team letting a coding agent touch production without a hard sandbox in front of it is running the same experiment these two just ran.
