EA deployed an internal AI chatbot called ReefGPT and mandated that developers use it as a tool in their daily work. According to a 2025 investigative report, employees said the tool frequently produced flawed code and errors that had to be fixed manually, in some cases costing more time than working without it.

Revealed through a Business Insider investigation in October 2025. EA required developers across studios — including those working on The Sims and Battlefield — to complete multiple AI training courses and to treat ReefGPT as a standard part of development. Workers reported that the chatbot's hallucinations (instances where it confidently produced wrong or nonsensical outputs) led to bugs in game code. A widely circulated internal Slack message mocking the executive AI mandate received widespread reactions from staff. EA's SEC filings acknowledge that AI systems "might present social and ethical issues."
