Gemini 4 Argon is Google’s latest flagship reasoning model for complex coding, agentic workflows, mathematics, science and long-horizon knowledge work. Google released the stable model gemini-4-argon on October 13, 2026.
Quick answer: Gemini 4 Argon supports a unified 1,048,576-token context window, multimodal input, code execution, computer use, file search, function calling, Search grounding and adjustable thinking levels. Introductory API pricing is $2 per 1M input tokens and $10 per 1M output tokens through November 30, 2026.
What is Gemini 4 Argon?
Gemini 4 Argon is Google’s newest frontier reasoning model. Google positions it for difficult real-world tasks across software engineering, agents, mathematics, science, finance, legal work and cybersecurity.
The stable model ID is gemini-4-argon, and Google lists the model as generally available from October 13, 2026.
What can Gemini 4 Argon do?
Argon accepts text, images, video, audio and PDFs as input and returns text output. Supported capabilities include:
- complex software engineering and code execution;
- autonomous multi-step agent workflows;
- computer use in preview;
- file search and URL context;
- function calling;
- Google Search and Google Maps grounding;
- structured outputs;
- multimodal reasoning;
- thinking levels: low, medium and high.
How large is the Gemini 4 Argon context window?
Gemini 4 Argon has a unified token limit of 1,048,576 tokens. Google documents a normal synchronous maximum output of 65,536 tokens, with long decode supporting much larger outputs through background execution.
Gemini 4 Argon pricing
Google is offering introductory Gemini API pricing through November 30, 2026:
| Usage | Intro price | From Dec. 1, 2026 |
|---|---|---|
| Input | $2 / 1M tokens | $4 / 1M tokens |
| Cached input | $0.10 / 1M tokens | $0.20 / 1M tokens |
| Output + thinking | $10 / 1M tokens | $20 / 1M tokens |
For developers, Argon is not available through the Gemini API free tier. Consumer availability is separate: Google says eligible Google AI subscribers can access Argon in supported Gemini and Search experiences.
How do you access Gemini 4 Argon?
- Gemini API for developers and enterprises;
- Google AI Studio for testing and development;
- Gemini app for eligible subscribers;
- AI Mode in Google Search for eligible subscribers;
- Google Antigravity for supported workflows.
Does Gemini 4 Argon support agents and computer use?
Yes. Google lists computer use as supported in preview and describes Argon as a model for autonomous multi-step agents. It also supports function calling, file search and long-running workflows.
Does Gemini 4 Argon generate images or audio?
No. Google’s model page lists image generation and audio generation as unsupported. The model can reason over image and audio inputs, but media generation requires another model or service.
What changed for developers?
Google recommends moving to the new model ID, reviewing output limits, selecting an appropriate thinking level, removing explicit context caching and using background execution for very long outputs.
Gemini 4 Argon vs older Gemini models
Argon is optimized for difficult reasoning and long-horizon work. Faster Gemini models may still be more appropriate for high-volume or latency-sensitive tasks. AI Finderz will track Argon alongside other releases on the Gemini Models & Versions page.
