Google launches Gemini 4 Argon: first frontier model of the Gemini 4 series, paying users get it first

Google has released Gemini 4 Argon, its first frontier large model since Gemini 3, aimed at complex science, coding and agent tasks. **Key points:** 1. **Built for hard problems.** Argon is optimized for highly complex science, coding and agent problems, and the API offers a unified 1 million token input and output limit, letting it take on longer and harder tasks. 2. **Claimed benchmark lead.** Google says Argon ranks first on Vals Index, a benchmark of professional tasks, and that the success rate of prompt injection attacks fell to 0.7% in testing. 3. **Paying users first.** The API launch price is $2/$10 per million tokens, doubling after November 30; the Gemini app and AI Mode in Search open first to Pro/Ultra subscribers, with no free-tier access for now. The frontier model race just got livelier. > Source: [read the original](https://blog.google/innovation-and-ai/models-and-research/gemini-models/introducing-gemini-4-argon/).
