# Google Gemini 4 Argon API

> Gemini 4 Argon is Google's flagship reasoning model and the first model of the Gemini 4 generation, generally available since October 13, 2026. Google trained it to keep context and precision across long, multi-step work such as complex software engineering, legal and financial research, and cybersecurity defense. It accepts text, image, video, audio and PDF input with a 1M-token context window, always reasons before answering with low, medium or high effort, and supports function calling and structured output.
