Sony and Warner Sue Anthropic for Illegal Use of Music to Train Claude

Público31 August 2026 at 13:44

Sony Music Publishing and Warner Records filed a lawsuit against the artificial intelligence company Anthropic, accusing it of using copyrighted songs to train its virtual assistant Claude. The publishers allege that Anthropic carried out a "blatant campaign" to illegally obtain works covered by copyright.

The lawsuit, filed in a United States federal court, seeks damages that can reach up to 150,000 dollars per musical track used without authorization. The music companies consider that Anthropic systematically violated copyright by reproducing and using lyrics and recordings of songs in the development of its language models.

Anthropic, the creator of Claude, has not yet publicly commented on the lawsuit. This action comes in the context of a significant increase in litigation between technology companies and copyright holders, who accuse AI companies of using protected content to train their systems without permission.

This lawsuit joins a series of similar legal actions brought by record labels and authors against technology companies in recent years, as the music industry seeks to protect its assets from unauthorized use by artificial intelligence systems.

AI assists police in solving 1.8 thousand cases in Paraná

Paraná's Secretariat of Public Security artificial intelligence platform assisted in solving 1,885 cases since December 2025, also contributing to 1,300 arrests and recovery of 557 vehicles. A survey by LCA Consultoria compared the Paraná program with São Paulo's, showing that, per camera installed, the Paraná system is 21 times more effective in capturing fugitives, 43 times in arrests in the act, and 108 times in vehicle recovery, operating with 972 cameras compared to São Paulo's 20 thousand.

AI and My Privacy

For over a decade, social media taught brands, entities and the State to build detailed profiles of each person, but artificial intelligence has eliminated the technical limits that previously existed. An AI system can simultaneously analyze language, behavior patterns, activity hours, images and even the emotional tone of messages, creating an almost complete reconstruction of who we are. The real risk is not in the technology itself, but in who uses it without effective regulation, in a grey space where data analysis companies and third-party platforms operate without supervision. When unknown entities can predict behaviors, influence political decisions or manipulate perceptions on a large scale, the functioning of markets and democracy is compromised. Portugal and the European Union have taken steps with the AI Act, but regulation always arrives after innovation. The response must be legislative, cultural and business-oriented, making ethics in data use a real competitive advantage.

There are people filming every movement of your day. All to teach robots to act like humans

Thousands of people in India are recording videos of their daily activities to train humanoid robots through artificial intelligence, collecting visual data that allows machines to learn to perform domestic tasks and other functions currently performed by humans. This phenomenon is part of a growing effort to develop robots capable of interacting with the physical world in a similar way to humans, using real human behavior data as the basis for their training.
