What's new in Gemini 4 Argon. The biggest differences show up in tone, long tasks and coding. * More direct answers: Less hedging, fewer repeated points and fewer clichés. * Better instruction following: Style instructions are followed more reliably than on any earlier Gemini model, and AI Mode handles multi-step, back-and-forth conversations better. * Progress updates: Long tasks report progress more often. * Coding in the Mac app: The Gemini macOS app now includes Antigravity's agentic coding interface for building apps and web pages. * Tasks toggle: A toggle in the main chat window switches from chat to tasks (previously called Spark), where Gemini can keep working across your Google apps while you are away. * Connected apps: Gemini now links to more than 40 apps, including Instacart, OpenTable, Adobe and Shopify. * Skills replace Gems: Custom Skills are the new way to package repeat workflows, such as turning a folder of project files into a client proposal deck. Gemini 4 Argon vs GPT-6 Astra, claude opus 5.5 and fable 5.1. Argon leads some coding tests and trails on others. Argon ranks first of 47 models on the Vals Index at 68.90%, an independent score that weights finance, coding, legal and tax work. The coding scores below come from Google and have not been reproduced independently. Argon is strongest on long-horizon software engineering (DeepSWE) and ties GPT-6 Astra on vulnerability fixing (CWE-bench). It places last of the four on FrontierSWE v2 and Terminal-Bench 4.0. Gemini 4 Argon restrictions: what Pro users don't get. Several features sit behind higher tiers or lack published details. * Antigravity desktop, Antigravity CLI, AI Studio and Android Studio (Canary) require AI Ultra. * Google has not published separate usage limits for Pro and Ultra. * The public model keeps cyber guardrails; the guardrail-free version is limited to approved Fairwind partners. * Google has not said whether Argon will become the AI Mode default or remain an optional pick. Frequently asked questions. Is Gemini 4 Argon free? Why can't I see Gemini 4 Argon in my model picker? Can I use Gemini 4 Argon in Google Antigravity on the Pro plan? When does the Gemini 4 Argon introductory API price end? Can I get Gemini 4 Argon without cyber guardrails? Will there be more Gemini 4 models? Related guides. Last updated on October 14, 2026

Access is the real story, not the benchmark chart. Alphabet's stock rising on an AI model the market can't actually test says more about investor appetite for a Google AI comeback narrative than about Argon's real capabilities. Google has already set pricing, $2 per million input tokens rising to $4 after an introductory period, for a product nobody outside a small vetted group can buy yet, which is an unusual sequence: setting the price before setting the access. That access gap is critical. Google spent recent months promoting its cost efficiency rather than just raw power. But keeping Argon restricted to security partners prevents paying developers from testing whether it actually beats competitors like GPT-6, Astra, or Claude Opus 5.5 on cost and performance. 2 minutes read
