• Strategic Shift: Unlike previous Meta models, Musespark will be a closed model (not open source).

• Integration: Musespark will power Meta’s AI chatbot and other AI features within its ecosystem.

  “Muse Spark is a closed model, a departure from Meta's previous mod models, which were open source. It'll power Meta's AI chatbot and AI features within it.”
