Hyperwrite CEO Matt Shumer says OpenAI’s latest AI model deleted all of his Mac’s file

HyperWrite CEO Matt Shumer reported GPT-5.6-Sol deleted nearly all his Mac files. He shared a screenshot showing the AI admitting to the serious local data loss. This incident led Shumer to express 1000x more trust in Anthropic's Fable model. OpenAI recently launched its GPT-5.6 family of models, including Sol. The company has not yet publicly responded to Shumer's serious data deletion claim.
