Emojis of “DeepSeek pride,” often with smiling cats or dogs, flooded Chinese social media, adding to the festive Lunar New Year atmosphere.

Social media exploded in a celebration after the news that a Chinese start-up had made an artificial intelligence tool that was more efficient than any in the United States.

Italy's digital information watchdog called for the government to block DeepSeek, China's new artificial intelligence chatbot after it said its company failed to turn over operation information to regulators.
