Two price curves for the same open weights are now moving in opposite directions — and that split says more about where open-model economics are heading than any benchmark released this week. DeepSeek and Zhipu have hiked their official API prices, while third-party hosts serving the exact same open

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

The evening round: a new benchmark for whether AI can actually design hardware, a prompt-injection trick that graduated into the spam underworld, and the day's smaller product and community moves. A new benchmark grades AI on circuit design, and Claude Opus 5 leads a field where OpenAI

Two very different AI stories landed on the same day. In Guangzhou, China used a 21-economy ministerial meeting to launch permanent regional AI institutions aimed at small firms — the clearest move yet to make its open-weight model stack the default for developing Asia-Pacific economies. And in a

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

Two releases this week attack the same blind spot: almost everything we can measure about AI infrastructure was built for training, and almost all the money is now being spent on inference. MLCommons shipped MLPerf Storage v3.0, and the headline is that the suite now tests inference workloads. Alongside

The neocloud that went from obscurity to a $45 billion Anthropic contract in under a year is now selling that story to IPO investors — and one of its suppliers is helping fund the pitch. Also: Roland finally ships a generative music tool, and it is deliberately not a song machine.

GitHub is shipping a new way of building coding agents: instead of picking one model and hoping it holds, its Copilot runtime now drafts, critiques, and escalates between models on the fly. The first benchmark numbers suggest the orchestration is doing real work, not just splitting the bill. GitHub'

The U.S. and China are opening a direct channel on AI risk for the first time in this administration, and a Beijing-based model lab is filing for one of the largest Chinese AI listings on record. Two different stories, one shared anxiety: that frontier agents and adversarial distillation

Anthropic is heading for an IPO that could value the Claude maker at $2 trillion — and the Long-Term Benefit Trust, the small group of self-appointed advisers who control a majority of Anthropic's board, is about to be examined by a much broader and less forgiving investor

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

Abu Dhabi's flagship AI company is shopping itself to Washington — and PUBG's parent is betting $250 million that India's AI appetite is real. G42 is exploring selling a majority stake to an American company, or spinning out an entirely new US-based vehicle, to
