Overview

About this model

Gemini 4 Argon is Google DeepMind's frontier reasoning model, built for long-horizon coding, knowledge work, and cybersecurity analysis. It offers a 1M-token unified context and output window, so you can feed in whole codebases, long contracts, or research corpora and get long, structured answers back in a single call. It accepts text plus an optional image and a system prompt. For faster, cheaper everyday chat, see Gemini 3.8 Flash; for the previous Pro tier, see Gemini 3.1 Pro.

1Long-Horizon Coding: Plan, write, and refactor across large repositories using the 1M-token context.
2Knowledge Work: Analyze long reports, contracts, and research papers and produce structured summaries.
3Cybersecurity: Review code and configs for vulnerabilities and draft remediation steps.
4Agent Reasoning: Use as the planner model inside multi-step agents and [workflows](/workflows).
5Visual Q&A: Pass an image_url to ask questions about screenshots, diagrams, or documents.

How to Use Gemini 4 Argon

  1. Write your prompt: Put the task in prompt. Optionally add system_prompt to set role, tone, or output format.

  2. Add an image (optional): Provide image_url to include an image in the request.

  3. Submit and fetch the result: POST returns a request_id; poll /api/v1/predictions/{request_id}/result or pass a webhook URL.

Common Questions

Frequently asked

What is Gemini 4 Argon?

Gemini 4 Argon is Google DeepMind's frontier reasoning model with a 1M-token unified context and output window, aimed at long-horizon coding, knowledge work, and cybersecurity.

How is Gemini 4 Argon priced?

Pricing is token-based at $2.00 per million input tokens and $10.00 per million output tokens, with a minimum charge of $0.0002 per call. Reasoning tokens count as output.

Does Gemini 4 Argon accept images?

Yes. Pass an image_url alongside your prompt to ask questions about a screenshot, diagram, or photographed document.

Can I set a system prompt?

Yes. Use the system_prompt field to control persona, tone, and response format.

How do I get the result?

The endpoint is asynchronous: you receive a request_id immediately, then poll the predictions result endpoint or supply a webhook URL to be notified when the text is ready.

How does Gemini 4 Argon differ from Gemini 3.8 Flash?

Argon is the frontier reasoning tier with a much larger context window, suited to deep multi-step work; Flash is optimized for low-latency, low-cost chat. Both use the same prompt, image_url, and system_prompt fields.
