❯ Google opens Gemini 4 Argon globally, targeting complex tasks that need sustained work

From early access to paying usersGoogle expanded access to Gemini 4 Argon on October 13. Developers can use the paid Gemini API; Google AI Pro and Ultra subscribers can access it in the Gemini app and AI Mode in Search, while Ultra subscribers can also use it in Antigravity. This is a wider rollout of the model announced on September 30, when access began with selected partners.

More room for a complete taskArgon targets multistep work in code migration, finance, law and cybersecurity. Google’s documentation specifies a 1 million token budget shared between input and output, rather than a million output tokens on top of a million input tokens. Its examples include refactoring large codebases, organizing professional materials, and finding and patching vulnerabilities.

Introductory pricing ends in NovemberThe introductory API price is $2 per million input tokens and $10 per million output tokens, with cached input discounted by 95%. After the introductory period ends on November 30, those prices become $4 and $20. Enterprise cost comparisons need to account for calls per task, output volume and cache utilization, rather than one unit price alone.

The chat window becomes a task interfaceGemini is also adding a chat-to-task toggle and connections to more than 40 apps for activities including grocery orders, restaurant bookings and business design. Its macOS app incorporates Antigravity’s coding interface. The practical test is whether delegation reduces rework and human intervention, rather than simply keeping the model busy longer.
