Following its announcement at the end of September, Gemini 4 Argon is starting to roll out to the Gemini app, Google Antigravity, and more. In the Gemini app, Gemini 4 Argon is now available to both Google AI Pro and AI Ultra subscribers. Last month, initial availability was limited to the Ultra ($99.99+) tier. Google says to expect frontier reasoning and improved performance across complex workflows. Google says Argon answers questions more directly with less hedging, avoids unnecessary repetition, and skips clichés. It also follows style instructions more reliably than any previous Gemini model, and on longer tasks it keeps users informed by sharing progress more often.
Given the major improvements in coding performance, Google is letting users switch between chatting and coding within the Gemini app for macOS. Users get direct access to Antigravity's agentic coding interface for building apps, web experiences, and more. A new toggle in the main chat window also lets users switch from chat to tasks, previously known as Spark. AI Pro and AI Ultra subscribers can access Gemini 4 Argon in AI Mode and the model picker.
In the Antigravity desktop app and CLI, the new model requires AI Ultra, as does access in AI Studio and Android Studio (Canary). Google shared internal examples: its Chrome team used Argon to separate core webpage handling from a ~6 million line legacy folder, finishing months of work in weeks. Another team reported a 2.85x inference speedup on Gemma 4 E2B, and a YouTube team used Argon to cut its comments frontend CPU footprint in half.
Argon is available in the Gemini API at an introductory price of $2 per million input tokens and $10 per million output tokens until November 30, 2026, after which it rises to $4 and $20. Google is also offering 10,000 scientists the highest usage tier in Google Antigravity free for six months, with applications now open.
