Appeals court rips federal judge over AI errors in Mississippi DEI law ruling

Key Points:

• Three OpenAI security researchers were fired after the company discovered they used disappearing messages on Signal, suspected of leaking information about a new AI model; the researchers deny mishandling sensitive data and claim they sought more safety collaboration.
• American Express announced a 5% global workforce reduction as part of a $336 million restructuring to become more agile and to prepare for increased use of artificial intelligence, including AI-powered customer service agents.
• Microsoft developed an AI model that diagnoses complex medical cases with 83.2% accuracy, more than twice that of generalist physicians, while also reducing costs by ordering fewer unnecessary tests.
• A federal appeals court overturned a ruling blocking Mississippi's ban on diversity, equity, and inclusion (DEI) initiatives after discovering the original order was drafted with AI assistance and contained numerous factual errors; the case will be reassigned to a new judge.
