Google's Gemini Spark, the persistent personal AI agent announced at I/O 2026, went live May 29 for US-based Google AI Ultra subscribers ($250/month). It runs in the background, reasons across Gmail, Calendar, and external services (Instacart, OpenTable), and executes long-horizon tasks with minimal oversight via a new 'Spark' tab in the Gemini side panel.
