Gemini app rolling out Gemini 4 Argon to AI Pro and AI Ultra
AI-summarised brief · reviewed before publication
Google has begun rolling out Gemini 4 Argon to its Gemini app, making the model available for both AI Pro and AI Ultra subscribers after an initial Ultra‑only release. The upgrade promises “frontier reasoning” and stronger performance on complex tasks, and introduces a seamless switch between chat and coding within the macOS Gemini app, leveraging Antigravity’s agentic coding interface for app and web development. A new toggle replaces the former Spark feature, allowing users to shift from conversation to task mode. Subscribers now see 3.5 Flash‑Lite, 3.8 Flash, 3.1 Pro, and 4 Argon in the model picker and can run Argon in AI Mode. In Antigravity desktop, CLI, AI Studio, and Android Studio (Canary), Argon remains limited to AI Ultra users. The Gemini API offers Argon at a promotional $2 per million input and $10 per million output tokens through November 30 2026, after which rates double. Google is also granting 10,000 scientists free access to its highest Antigravity usage tier for six months.
💡 Why It Matters
- · By extending Argon to a broader subscriber base and integrating coding tools directly into the consumer app, Google blurs the line between conversational AI and development environments, accelerating real‑time AI‑assisted software creation.
