Google's Gemini 4 Argon ships with 1M output tokens at $2/$10, but only vetted cyber defenders get access
Google's September roundup leads with Gemini 4 Argon, which it calls its next era of frontier intelligence. The defining specification is an industry-leading 1-million-token output limit, built for heavy workloads such as large code generation, financial research, legal drafting and autonomous cybersecurity patching. Fortune frames it as Google's journey back to the frontier, its first flagship since February. Reported benchmarks include 77.9% on DeepSWE v1.1, 68% on CWE-bench v1 and 84.2% on GraphWalks 256K-1M. Artificial Analysis says Argon matches GPT-6 Astra on its Intelligence Index at 60% of the cost per task, a result Demis Hassabis retweeted.
Access is the catch. Because of autonomous exploitation risk, Argon is available only through the Fairwind Program for vetted cybersecurity defenders, to Google staff, and to US government evaluators. Pricing has been announced at an introductory $2 per million input and $10 per million output tokens, with a 95% cache discount. Developers say post-introductory pricing rises to $4/$20. Google also officially discontinued Gemini 3.5 Pro. The same month brought Gemini 3.8 Flash, 3.8 Flash Cyber and Gemini 3.8 Live voice models.
In competitive terms, Argon lands in a market where frontier labs are holding back their most capable models. OpenAI just cancelled GPT-6.1 Astra over similar cyber concerns, so gated access is becoming the norm for top-tier models instead of a Google quirk. On benchmarks the picture is mixed. Its DeepSWE score roughly matches Claude Opus 5.5 High rather than clearly beating it, and Astra still leads FrontierSWE v2.
The skeptical takes are loud. Developers mocked Google for still being unable to shake "can't release a model" jibes, especially since paying Pro and Enterprise customers are locked out. Others warn that Vertex AI's finicky prompt caching will make post-introductory pricing uneconomical for production agents. Sentiment is more positive around the Antigravity environment, where testers reported Argon attaching GDB to kernel drivers and writing custom C shims. Watch for a general-availability date and whether the cyber gating loosens.
