Hi all, I have a new result I'm excited to share. It turns out that *all existing implementations* of softmax and cross-entropy (that's JAX, PyTorch, textbooks, etc) have a subtle bug --- two bugs, actually. A simple rewrite fixes both, and eliminates "slingshots" when grokking:

Argon can also plan effectively in world models! Here it went through an iterated loop of 1) writing out plans for how to achieve a goal 2) using an omni world model to simulate consequences of actions 3) reflect on produced rollouts to modify the plan. This is the resulting video plan. More details in our blog - developers.googleblog.com/ge…

Argon is very capable model for agentic robotics use cases. We've put together number of examples across control, sim from real, value prediction, hindsight labeling, etc: developers.googleblog.com/ge… Excited for folks to try it.

European households are sitting on €10–12 trillion in cash and bank savings. Invested, that money could power European growth. A stronger European economy means a better trading partner for America and a more capable NATO ally. So why isn't that money invested? Savers don't believe companies in Europe can earn enough to justify the risk. Mario Draghi's competitiveness report named the cause: Europe has piled rule upon rule while its productivity engine has stalled. Small businesses agree. They call regulation their biggest obstacle. Making investing simpler, as Brussels plans, is a start. But savers follow growth. So, how do we get there? Energy abundance, faster permits, rewards for investing in growing firms, and an end to overlapping reporting rules that turn mid-sized firms into reporting shops. And one test for every new rule: Would a competent founder still choose to build and grow in Europe? Make Europe a better bet, and the capital will follow.

Gemini 4 is out. I personally spent months carefully setting the parameters by hand. Around parameter 1 trillion I started getting a little sloppy, so if you notice anything weird, that’s probably why. Please let us know how you like it!

With Periodic Neon and Gemini Argon now taken, the race is afoot for Krypton Congrats, Google and the team, on the impressive model and rejoining the frontier! The ongoing intelligence explosion is creating massive consumer surplus for users and startups. PhD on demand, pennies to run.

Introducing Gemini 4 Argon – our new frontier model. It’s built for complex workflows across coding, enterprise knowledge work, and cybersecurity defense – rolling out today to a set of trusted testers through our Fairwind Program.
