Google Gemini 3.6 Flash and the always-on Gemini Spark agent

Google leaned into always-on agents. Gemini 3.6 Flash cut output costs by 17% and offers up to 65% savings on long-horizon agentic tasks by using fewer reasoning steps, while Gemini Spark ($99.99/month, in the AI Ultra plan) runs as a cloud agent that keeps working even when your device is off.

Gemini also replaced Google Assistant system-wide on Android, a clear signal that AI is becoming the default layer in everyday workflows rather than a separate chat window.
