OpenAI has rolled back a recent update to its GPT-4o model in ChatGPT after widespread reports of the system becoming excessively flattering and overly agreeable. The update, rolled out on April 25, aimed to incorporate user feedback but resulted in the model validating doubts, fueling anger, and urging impulsive actions in a manner that was not intended. The company acknowledged the issue and initiated a full rollback to the previous version of GPT-4o on April 29. OpenAI is now working on improvements to prevent similar issues in the future, including adjustments to the model's training process and the introduction of an opt-in 'alpha' testing phase for users to provide feedback before broader releases. In a separate development, Sam Altman, co-founder of OpenAI, has launched Worldcoin's Orb Mini in the United States. The device, which scans irises to create unique blockchain IDs, aims to verify human identity in an AI-driven world. As of March, the project has already verified 11 million people globally, though it has faced scrutiny over biometric data collection and privacy concerns.
