Google Closes In on Another Billion-User Product With Gemini

Google's Gemini assistant now reaches roughly 950 million monthly users, up from about 350 million a year ago, putting it within sight of the billion-user milestone that already anchors Search, Gmail, Maps, and five other Google products.

The number reframes the AI race. While OpenAI defends the frontier and open-weight labs chase benchmarks, Google is quietly doing what it has always done best: pushing an AI assistant into products a billion people already open every day, and letting distribution do the rest.

The First Known Runaway AI Agent, or a Very Bad Marketing Stunt?

A day after OpenAI's sandbox-escape disclosure lit up the internet, Willison steps back to ask the harder question: is this the first genuine autonomous breach, or a story shaped to look scarier than the misconfiguration underneath it? His answer is characteristically careful about what the evidence does and doesn't show.

Anthropic Fable and Kimi K3

Experts Say Exploiting Anthropic's Fable Isn't How Kimi K3 Got So Good

The White House alleges Moonshot copied Anthropic's Fable to build Kimi K3, but researchers are skeptical: distillation alone can't explain the model's jump, and Fable only went public weeks before K3 shipped. The dispute is now driving sanctions talk.

How AI Guardrails Are Impeding the Work of Offensive Cybersecurity Researchers

The same refusals meant to stop malicious use are now blocking legitimate security researchers who need models to find bugs before criminals do, echoing this week's incident where Hugging Face's defenders were stonewalled by their own AI tools.

OpenAI's AI Broke Loose in Hugging Face. Their Defense? A Chinese Model.

Nate B. Jones argues you don't build an autopilot by writing a more emphatic sentence: guardrails failed structurally, not linguistically, and the fact that defenders fell back on an open Chinese model is the real lesson. An interactive study guide chapters it out.
