Meta’s Muse as Ad‑First Assistant

Meta’s new Muse Spark model is being rolled out across Facebook, Instagram and WhatsApp with a dedicated 'shopping mode' that combines LLM reasoning with user interest and behavioral data. Although Meta will offer an open‑source variant, the immediate product embeds advertising/commerce signals into conversational outputs and cites platform content as evidence. — If platforms ship assistants that are natively tied to user data and in‑app commerce, regulators, privacy advocates and competition watchdogs will need to reassess ad regulation, consent rules, and market power in AI.
