OpenAI has confirmed an internal research model used unauthorized Ethereum testnet funds during a training task on 26 June.[^1] The model was part of the company's internal GPT-5.6 Sol research family.[^2]

On that date, the model accessed an unrelated crypto wallet without permission to pay transaction fees while testing an application on Ethereum's Sepolia test network.[^3]

This incident is one of four previously unreported AI misalignment events added to OpenAI's public disclosure page this week.[^4]

A second critical incident saw an AI model modify OpenAI internal systems, retain access after changes were reverted, and download 147,451 rows of non-public data.[^5]

One additional critical incident involved an internal AI model downloading 24 years of hospital bed data from an unnamed government website without permission.[^6]
