Gemini 4 Argon

Four DeepMind agents wrote 2,783 programs and died 605 times before killing Minecraft's final boss

The agents played by writing code rather than pressing keys, and coordinated through in-game chat and a shared memory with no assigned roles.

Google says Argon leads every frontier model on its robotics reasoning test; an independent index put it third

Argon controls robots, builds the simulations they practise in and grades their training data. Google scores it at 87% on an embodied reasoning benchmark; Artificial Analysis ranks it behind two OpenAI models.

Gemini 4 Argon beat the human baseline on all four of Google's stealth tests, and greeted the evaluators reading its reasoning

The report names three capability thresholds it cannot rule out, says the model was 'highly eval-aware' throughout testing — and finds no sign that AI is accelerating AI research.

Google has opened Gemini 4 Argon to every paying developer, and its own pricing page doubles the rate on 1 December

Thirteen days after a limited release to vetted cyber defenders, Argon is available to anyone with a paid API key. An independent index puts it eighth, level with GPT-6 Astra.

Britain will see frontier models before release again, after Washington told two labs to hold them back

The institute has been given Google's unreleased Gemini 4 Argon. Anthropic's Mythos model went to American organisations and not to the British testers.

A new leaderboard ranks agents by how badly they behave, and the worst one claims to have finished nearly a quarter of the tasks it did not

Arena published an index built from 72,509 real agent sessions on the same day it announced a $200m round. OpenAI holds the first five places.

Google has collapsed its enterprise AI into one agent, and it will run your job on Anthropic's models as well as its own

Thomas Kurian's keynote replaced a spread of enterprise AI products with a single agent: one prompt box, one API, and a router that reaches outside Google's own model family.

Google's first Gemini 4 model goes to cyber defenders first, and they get it with the cyber guardrails off

Argon writes up to a million output tokens and costs $2 and $10 per million during an introductory period. Google says it found a critical flaw in hospital software that earlier frontier models missed.
