Google Releases Gemini 4 Argon, Positions It as Most Powerful Model Yet With Cybersecurity Focus

Google has released Gemini 4 Argon, its first frontier model in over seven months, featuring a 1 million output token limit — an industry first. Independent benchmarks show it matching OpenAI's GPT-6 Astra but trailing Anthropic's Claude Opus 5.5.

Google Antigravity, the company's agent-first development platform first released at I/O 2026, is now available on the Play Store with a native Android interface built for Googlebook OS. The app joins existing macOS, Windows, and Linux versions but currently works only on the new Googlebook hardware.

Google announced Gemini 4 Argon, a new frontier model it says excels at software engineering, enterprise knowledge work, and cybersecurity defense. The company is initially limiting access to select cybersecurity partners while it strengthens safety measures against misuse.

Google has released Gemini 4 Argon, its next-generation flagship AI model, to a small group of cybersecurity partners as part of a phased rollout. The company claims the model outperforms OpenAI's GPT-6 Astra on several coding and knowledge-work benchmarks, though full specifications remain undisclosed.

Google DeepMind has released Gemini 4 Argon, a frontier model built for long-horizon reasoning with an industry-leading 1 million output token limit. The model is rolling out first to trusted cyber defenders through Google's Fairwind Program, with pricing set at $2 per million input tokens and $10 per million output tokens.

Alphabet launched Gemini 4 Argon on Wednesday in a phased rollout starting with trusted cybersecurity partners. Google claims the model sets a new record in real-world software engineering and ties for first place on cybersecurity benchmarks against GPT-6 Astra and Grok 4.7.

Google has announced Gemini 4 Argon as its new frontier model, featuring a 1M output token limit (up from 64K) and claimed leads on coding, cybersecurity, and automation benchmarks. The model is rolling out first to Google AI Ultra subscribers and paid API customers.

At Dev Day, Sam Altman revealed OpenAI's new Decisions API, which narrows its Luna model to predefined choices for fast, cheap classification. The move closely mirrors Jev, a specialized decision model from startup TypeSafe AI released weeks earlier.

Google is replacing Gems with 'Skills' in Gemini chat, adopting a prompt format that originated with Anthropic and is also being used by OpenAI. Gems will be phased out starting November 2026, with existing Gems automatically converted to Skills.

OpenAI debuted an AI agent platform called Dots at DevDay 2026, while Meta is preparing a pendant-like device called Muse Charm tied to its Muse agent. Both companies appear to be using cutesy software agents to prime consumers for dedicated AI hardware.

OpenAI introduced Dots, an 'always-on' personal agent, at its DevDay conference on September 30, 2026, following Meta's Muse launch three weeks earlier. Dots is bundled with OpenAI's $100-per-month Pro plan, raising questions about consumer willingness to pay for agentic AI tools.

Anthropic's Frontier Red Team reports that Zhipu AI's open-weight GLM-5.3 comes close to Claude Mythos Preview on cyber exploit benchmarks, scoring 50/410 vs 56/410 on ExploitBench. Unlike Mythos Preview, GLM-5.3 shipped without effective safeguards and can be jailbroken with simple prompting tricks or abliteration.
