100-word summary
Meta launched Muse Spark, a new model that splits complex questions into parallel tasks handled by multiple AI subagents simultaneously. Ask it to plan a trip and one agent drafts the itinerary while another compares hotels in real time, then they synthesize an answer. The model already powers Meta AI and will roll out across WhatsApp, Instagram, and Ray-Ban glasses in coming weeks. The twist: Meta is keeping this one private, offering API access only to select partners instead of releasing open weights. It's a sharp turn for a company that built its AI reputation on open-source models, signaling Meta now sees speed-to-market beating community goodwill.
