Meta, the parent company of Facebook, is introducing smart assistants powered by artificial intelligence (AI) across its apps, including Instagram, WhatsApp, Messenger, and Facebook. The rollout, powered by Meta's AI model LLaMA 3, aims to bring AI-powered assistance to billions of users in meaningful ways. Users will be able to ask Meta AI for help with tasks and information, and the technology will be integrated into various parts of the apps. Meta's move stands out due to the massive scale of its apps, which are used by nearly four billion people worldwide each month. The AI assistants will be free to use and will enhance user experiences within Meta's apps.
