Gemini 4 Argon API FAQ

What is Gemini 4 Argon?

Google's flagship model for reasoning, agentic coding, long outputs and multimodal work across text, images, audio, video and PDFs.

Does the 1M figure mean context or output?

Context. Argon has about 1,048,576 tokens of context shared by input, thinking and output; a single response returns up to about 65K tokens.

How do thinking levels work?

Choose low, medium or high. Higher levels reason longer on hard tasks; thinking tokens are billed at the output rate.

Does it support tools and structured output?

Yes, function calling and structured JSON output are supported, and responses can stream.

How is it billed on 01router?

Per 1M input and output tokens. Google's introductory pricing may change, so check the pricing table on this page for the current rate.
