Per testingcatalog, Google's new Gemini 4 Argon model has begun rolling out in Agent Studio on GCP. The UI bills it as a frontier model for complex real-world software engineering and enterprise knowledge work, with an industry-leading 1M output token limit. The same menu also lists the new Nano Banana 2.1 image model. Google AI Studio and Gemini apps are expected to follow; the model is already testable in Agent Studio.
