Llama copyright drama: Meta stops disclosing what data it uses to train the company's giant AI models

• Meta released a huge new AI model called Llama 2 on Tuesday. 
• The company didn't disclose what training data was used to train Llama 2. 
• That's unusual. The AI industry typically shares many details of AI training data sets.

A major battle is brewing over generative AI and copyright. Publishers want to be paid if their work has been used to train large language models. Big tech companies would rather not pay.
