Elon Musk called for a “complete overhaul” of X’s recommendation algorithm after AI researcher Andrej Karpathy complained about negativity and hostility on the platform regarding his views on Anthropic’s Claude Tag feature. Karpathy praised Claude Tag as a major shift in user-AI interaction, describing it as a persistent, context-aware teammate for organisational workflows. His comments drew mixed reactions, with some users mocking the comparison and others defending him. Karpathy later lamented the “increasingly toxic nature of discourse on X,” and Musk responded by agreeing that the platform’s recommendation algorithm required a “complete overhaul.”
