Translation: The latest large language model, Llama2, released by Meta has been mired in controversy due to its failure to meet the requirements of the open-source initiative. Joelle Pineau, Head of AI Research at Meta, stated that the openness needs to balance the benefits of information sharing with the potential business costs. Meta is actively involved in establishing standards for AI models and guidelines for their safe deployment, advocating for collaboration with industry organizations. This move has drawn attention to the limitations of open-source licensing in the commercial sector.
