The Meta AI app, built with the company’s Llama 4 AI system, includes a “discover” feed that lets users see how others are interacting with AI.

Microsoft says AI now writes up to 30% of its code, while Meta predicts AI will handle half of Llama development within a year.

At Meta’s LlamaCon conference, Satya Nadella shared whether AI is better at writing Python or C++ and asked Mark Zuckerberg how much Meta code is written by artificial intelligence.
