What Google DeepMind announced
On 13 Oct 2026, Google DeepMind released Gemini 4 Argon — agentic flagship for paid developers, price doubles 1 Dec for chat / reasoning work. More agentic functionality, including persistent tasks that continue while you are away, and connections to 40+ external apps.
Google’s official announcement, on 13 October 2026, describes Argon as built for deep, multi-step work in coding, finance, law, cybersecurity and science, and as available to paid developers and enterprises through the Gemini API, with Google AI Pro and Ultra subscribers getting it in the Gemini app and AI Mode in Search, and Ultra subscribers getting it in Antigravity. The price point is the part to budget carefully: $2 per million input tokens and $10 per million output tokens is an introductory price, with $4 and $20 applying from 1 December 2026.
What it costs, and who can use it today
Price: Intro $2 input / $10 output per 1M tokens to 30 Nov 2026, then $4 / $20. Access: General. Availability: Paid API developers from 13 Oct 2026; Gemini app gains more agentic features. A token, where prices are per million tokens, is roughly part of a word; prices are per million tokens processed, not per message. Open-weight means downloadable weights — check the licence for commercial use, because downloadable does not automatically mean unrestricted.
Why it matters
The price step on 1 Dec is the story, not just the launch. Anyone budgeting on the intro price needs the second price in the same paragraph.

Official sources are listed first, because a lab’s own announcement or product page is the primary source for price, access and availability. Secondary coverage is listed second, and is never used to upgrade an unverified figure into a settled fact.
