Google DeepMind

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.

An AI agent solved 49 of 50 unpublished physics problems, and cutting off its internet access cost it three

TheoPhysEval was built from problems working physicists had not published, precisely so no model could have seen them. The best agent missed one, at an average cost of about $2.33 a problem.

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 Deep Review to the public, after running it over more than 16,000 conference manuscripts

The tool grew out of a pre-submission experiment at four computer science conferences. Google frames the problem as a validation bottleneck: papers are now produced faster than people can check them.

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.
