A federal judge has ruled that Anthropic's use of books to train Claude falls under fair use, and is legal under U.S. copyright law.
From the ruling: 'Like any reader aspiring to be a writer, Anthropic's LLMs trained upon works not to race ahead and replicate or supplant them – but to turn a hard corner and create something different.'

Full ruling here. Expect future cases to spend more energy on substitute for the original. Not sure this is a final word or they made the best case.

Positive ruling for AI. There must be a fair use concept for training data or models would be crippled. China is going to train on all the data regardless, so without fair use, the U.S. would lose the AI race.
