Gemini 4 Argon is Google's flagship reasoning model, built for complex software engineering, deep mathematical and scientific problem solving, and autonomous multi-step agents. It is available on AI/ML API through the chat completions endpoint as google/gemini-4-argon.
Google reports Argon ahead of competing models from OpenAI and Anthropic on several benchmarks, including long-video understanding. These are vendor-reported results and have not been independently reproduced.

Google describes Argon as built for agentic software engineering, including analysing fleet-wide profiling telemetry and migrating C/C++ codebases with agents running over long horizons.
It is also positioned for deep mathematical and scientific problem solving, and for autonomous multi-step agents that keep working across many sequential tool calls.
The 1,048,576-token context window suits long-document and multi-file analysis, and image input allows multimodal document and screenshot understanding.
