Google announces Gemini 4 Argon as its new frontier model
Gemini 4 Argon is Google’s “next era of frontier intelligence” and built for “deep reasoning across complex, long-horizon workflows.” It follows the cancellation of Gemini 3.5 Pro and focus on 3.8 Flash.
With this new model (which has a new naming scheme), Google wants to offer “frontier-level capabilities” across coding, knowledge work, cybersecurity defense, and creative writing.
Gemini 4 Argon’s output token limit is 1M tokens (up from 64K) to allow for longer and more complex use cases. This is paired with expanded coding, reasoning, and multimodal capabilities.
When the model has the headroom to think deeply and generate hundreds of thousands of tokens in a single trajectory, it adds a new level of depth in reasoning to solve tough problems in one go.
In terms of benchmarks, Google touts a DeepSWE v1.1 score of 77.9%. Claude Opus 5.5 comes in at 74.2% followed by GPT-6 Astra’s 74.1%.
Google trained Gemini 4 Argon to be “highly capable at cybersecurity defense” with leaps over 3.8 Flash Cyber. The model will be made available “without cyber guardrails” to trusted defenders and internal Google teams so that they can “leverage its full frontier-level cybersecurity defense capabilities.”
Outside of coding, Gemini 4 Argon also has “leading performance across other domain specific evaluations,” such as Vals Finance Agent v2 (multi-step financial research) and Harvey’s Legal Agent Benchmark (legal research and drafting).
Gemini 4 Argon is “rolling out soon,” starting with Google AI Ultra subscribers and paid API customers.
So far, it has been made available to trusted testers and cyber defenders (via Fairwind Program). Before the broader release, Google is focusing on:
Inside Google, Gemini 4 Argon is already powering internal workflows with “thousands of Googlers highlighting the model’s strengths in specialized coding tasks, conducting deeper research, and writing quality.” The company shared some examples today:
