Google DeepMind releases Gemini 4 Argon, returning Google to the frontier

Google DeepMind released Gemini 4 Argon today, marking Google's first major flagship model upgrade since Gemini 3 Pro last November and a minor 3.1 Pro bump in February. The release follows a summer in which Google shipped four rapid updates to its faster, lower-cost Flash line while the promised Gemini 3.5 Pro stayed in testing, and Every frames Argon as putting Google back in the frontier conversation.
