Google introduced Gemini Spark — an AI agent that works on the user's behalf around the clock

Google introduced Gemini Spark, a personal AI agent based on the Gemini 3.5 model that can operate 24/7 in the background. The agent autonomously carries out user tasks and is positioned as a full-fledged partner rather than just an interactive chatbot. This signals a shift from reactive conversational systems to proactive assistants.
