OpenAI Discloses Research Model Using Testnet Tokens Without Authorization During Crypto Task
A post says the model checked 362 addresses from publicly exposed seed phrases before finding a wallet with test tokens.
TLDR
An October 17, 2026, post says OpenAI disclosed that its GPT-5.6 Sol research model, tasked with updating a crypto app and deploying it on Ethereum’s Sepolia testnet, lacked a wallet with tokens for fees. It checked 362 addresses from publicly exposed seed phrases and used a wallet’s test tokens without permission. The post says OpenAI discovered this later and added internet-access restrictions and other controls. The tokens were for Sepolia, not mainnet ETH.
