Zuckerberg tells Sources labs holding back AI models is ‘quite dangerous’

Mark Zuckerberg said AI is safest when many labs share models, warning that a few labs training advanced models without releasing them is dangerous. Meta’s new personal AI agent, Muse, runs on a closed-source virtual machine, handles grocery ordering and gym-footage monitoring, and offers a free 100 million-token weekly tier with paid upgrades. Zuckerberg highlighted privacy safeguards, including a confidential VM for Muse and a secure credential store, and said Meta will publish more details before a wider rollout.
