Judge rules Anthropic can legally train AI on copyrighted material

This has led a group of authors to sue Anthropic, the company behind the AI chatbot Claude. Now, a US federal judge has ruled that AI training is covered by so-called "fair use" laws and is therefore legal, Engadget reports. That is, the resulting work must be something new rather than it being entirely derivative or a substitute for the original work. This is one of the first judicial reviews of its kind, and the judgment may serve as precedent for future cases. However, the judgment also notes that the plaintiff authors still have the option to sue Anthropic for piracy.
