Three platforms take different technical approaches to AI creative: Meta uses conversational signals to auto-generate variants, Google Asset Studio generates video and image assets with Veo/Imagen, and TikTok Symphony repurposes existing content through CapCut integration. Which one fits your workflow depends on your primary platform and where your creative production breaks down.
Meta set Advantage+ as the default for new campaigns in May 2026, added AI voiceover and AI-generated music, and integrated conversation signals from 1 billion Meta AI users. Early data shows 8-15% ROAS lift but significantly less creative control. Which settings can still be overridden versus locked, and how cross-border advertisers adapt.
Meta cut the ASC weekly conversion floor from 50 to 25 and sunset Marketing API V25 on May 19, 2026. Stores doing 3-4 sales/day can finally use ASC. But a lower entry bar does not equal a working campaign — CAPI quality, creative count, and conversion stability still gate performance.
