Study: ChatGPT builds an 'algorithmic self-portrait' of users

Researchers at Max Planck Institutes analyzed ChatGPT conversation histories from 80 users and found 2,050 memory entries across 65 of them. In 96% of cases ChatGPT created or updated memories without an explicit user request, and 52% of entries contained information about users' psychological states.

• ChatGPT stored user data without a request in 96% of cases
• 52% of memory entries covered users' emotions, desires and beliefs
• Some memories relied on wrong inferences, such as a user liking Nirvana
• Since June OpenAI auto-updates user profiles and uses them for ads
