The references occurred in response to specific and controversial themes, such as those related to the Iranian government and the Holocaust. For example, the model cited Grokipedia when asked about the relationship with the Iranian telecommunications company MTN-Irancell and about historian Richard J. Evans.
Conversely, Grokipedia was not used for other controversial topics, such as media bias against Donald Trump.
GPT-5.2 was released in December and is intended to improve performance in professional tasks. Grokipedia itself has previously been a subject of debate for citing neo-Nazi forums.
OpenAI explained to the Guardian that while it searches a wide range of public sources, it applies safety filters to reduce the risk of links appearing that are associated with high-severity harm.
