Long-horizon reasoning
Supports extended reasoning trajectories and outputs of up to 1 million tokens, up from the previous 64K-token limit, for complex problems that may require many steps.
A frontier AI model for long-horizon coding, enterprise knowledge work, and cybersecurity defense.
Gemini 4 Argon is a frontier AI model for complex, long-horizon workflows across real-world software engineering, enterprise knowledge work, and cybersecurity defense. It combines reasoning, coding, and multimodal capabilities to support tasks that require sustained analysis, large amounts of context, and multiple steps.
The model supports an output limit of up to 1 million tokens, enabling extended reasoning and generation for work such as code migration, technical research, legal drafting, financial analysis, and visual understanding. It is currently rolling out to trusted cyber defenders through Google’s Fairwind Program while Google continues testing safeguards ahead of broader availability.
Supports extended reasoning trajectories and outputs of up to 1 million tokens, up from the previous 64K-token limit, for complex problems that may require many steps.
Handles workflows ranging from everyday debugging and algorithm design to large-scale C/C++ codebase migrations and optimization work.
Shows leading performance in reported evaluations for financial research, legal research and drafting, tax-related work, and end-to-end business-function execution.
Can analyze professional charts, identify details in long videos, and act based on information distributed across a series of documents.
Can autonomously find, validate, and patch critical software vulnerabilities; Google is releasing it to trusted defenders without cyber guardrails for defense work.
Engineering teams can use Argon agents to help migrate C and C++ systems to Rust, including codebases ranging from core libraries to the Fuchsia Zircon kernel, with auditing, emulation testing, and review before production.
Researchers can apply the model to demanding investigations such as quantum algorithm optimization, where Google reports an example of improving a published baseline by 40%.
Knowledge-work teams can use Argon for multi-step financial research, legal research and drafting, and related enterprise analysis where sustained reasoning is required.
Trusted cyber defenders and internal security teams can use Argon to locate, validate, and patch critical software vulnerabilities, including risks in software used by public infrastructure.
The model is initially rolling out to a set of trusted cyber defenders through Google’s Fairwind Program. Google says it plans to expand availability to developers, enterprises, and consumers, but the source does not specify a public access process or release date.
Gemini 4 Argon is designed for complex, long-horizon workflows in software engineering, enterprise knowledge work such as legal and finance tasks, and defensive cybersecurity.
Gemini 4 Argon has an output token limit of up to 1 million tokens, compared with the previous 64K-token limit cited by Google.
Google announced an introductory price of $2 per million input tokens and $10 per million output tokens. Cached input tokens are priced at 95% below the input-token price.
