Gemini 4 Argon Tokyo Meetup

Turn your next idea into a working AI app with Gemini 4 Argon.

Join AI Builders and Google in Tokyo for an evening of expert insights, hands-on learning, and building with Google's newest frontier model. Meet fellow developers, learn directly from Google leaders, and put Gemini 4 Argon to work in your own app using Google AI Studio and Google Cloud Platform.

Why build with Gemini 4 Argon?

Argon brings deeper reasoning and stronger software engineering capabilities to ambitious projects, from debugging code to tackling complex, multi-step workflows. Explore what its new capabilities can unlock for your next product:

More room for your ideas: A unified one-million-token window lets you work with extensive context, with input, reasoning, and output sharing the same budget.

Reasoning you can tune: Low, medium, and high thinking levels let you balance depth, response time, and token use for your task.

Built for sustained work: Longer responses and multi-step reasoning support demanding coding and agent workflows.

Beyond text: Multimodal capabilities and agentic video understanding open up ways to build apps that interpret visual information and act on it.

Go from inspiration to experimentation: hear the big picture, follow a practical workshop, then spend a full hour building something of your own.
