New models, papers, and benchmarks

Two things are worth your attention this morning: a Chinese open-weight model just took the number-one slot on OpenRouter's weekly leaderboard by volume, and Washington is quietly drafting the agenda for the first dedicated US-China AI safety dialogue of Trump's second term. Both

Two posts from OpenAI landed within hours of each other on Sunday, and together they say something the company has spent a year avoiding saying out loud: the automation is working faster than the safety case for it. OpenAI says it has hit its "automated research intern" goal,

A new sandbox drops multimodal models into a photoreal, physically simulated replica of Hong Kong and asks them to do something benchmarks rarely test: walk somewhere. They can describe the street. They can't reliably get across town. UrbanGround, from a team spanning Shanghai Jiao Tong University, the National

Two launches this cycle push AI out of the chat window and into the two places the field has been slowest to land: structured data tables and real-time video. Xiaomi open-sourced a tabular foundation model that challenges gradient-boosting stalwarts without fine-tuning, and fal's new

Three stories this morning, all about who is moving the numbers — and who is supposed to trust them. OpenAI's metrics for GPT-6 Astra changed between snapshots, a Reddit practitioner's side-by-side gives the first noisy real-world comparison against Fable 5.1, and Kalanick&

Two stories out of China this morning, and they point at the same pressure: the industry has moved past "the model answered correctly" and into "does this hold up in the real world." Wenge AI has published the full technical report for Decitron, a "general

Two medical AI stories landed within hours of each other, and read together they trace the field's central argument: the machines keep doing things nobody has done before, while the people who measure them still can't agree on what a result actually proves. A Chinese military

The day's throughline was that capability is no longer the bottleneck — distribution, verification, and ownership are. Anthropic's agents closed out a 20-year-old mathematics benchmark in eleven days while a mathematician confirmed the work was correct, Huang explained that he paid $12.9 billion to

Ant Group's open model team spent the day pushing Ling into vision, while the local-inference crowd shipped two things you can actually run tonight: a denser weight format for ternary models and the first serious head-to-head of 27B quants on a 16GB card. Ant Ling

A new benchmark grades AI-generated circuits the way hardware is actually graded — in a simulator, against real datasheets, at every tolerance corner. The early results are better than anyone expected and nowhere near good enough. OpenAI put a printed circuit board in a GPT-6 Astra demo, and the

Anthropic says a team of Claude agents produced the first complete, machine-checked formalization of Fermat’s Last Theorem — and Kevin Buzzard, the Imperial College London mathematician who has spent years on the same problem, has already compiled the result and confirmed it checks out. Also today: React’s compiler

M.G. Siegler is right that calling GPT-6 Astra "AGI" is marketing. He is wrong that OpenAI alone is to blame. When Greg Brockman stood in front of reporters last Thursday and told them "we are now in the AGI era," he was performing exactly
