Two stories about where models are being pointed today: a student simulator that beats frontier models at being one particular learner, and Meituan's shopkeeper agent crossing a million restaurants. Microsoft researchers trained a 4B model to imitate individual students — and it beats GPT-5.4 and GPT-4o

Today's board is unusually infrastructural. The fresh momentum is not another coding assistant but the layer underneath it: a model small enough to sit on the device, sandboxes that hand an agent a whole computer, a self-hosted control plane for the agents a company runs, and the

State capitals spent 2026 passing laws about chatbots and children. An NPR investigation says one of the biggest chatbot makers helped write the language — and the language has holes in it. Google helped draft and lobby for chatbot-safety bills in at least ten states this year, and several of

Jev's whole pitch was that decisions do not need generated text. Someone has now rebuilt that pitch with open weights, on a laptop, with the benchmark table to go with it. China's APUS AI Lab published fast-browser-use, an open-source reproduction of Jev'

The leaked number everyone is quoting is the smaller one, and it got better. The Financial Times reported Friday that OpenAI expects negative free cash flow of $278 billion between 2026 and the end of 2030, according to a presentation the company prepared in July for a computing deal. The

Two signals from the weekend, one about money and one about words: the AI spending forecast went up again, while the president of the United States ran a poll on what to call the technology. Gartner raised its forecast for worldwide AI spending in 2026 to $2.7 trillion, a

Two fresh data points land the same way: the money AI is saving is showing up as losses somewhere else — in the pay of the graduates who were supposed to build it, and in the electricity and hardware nobody budgeted for. Computer science graduates are entering the worst job market

Artificial intelligence is the goal — getting a machine to do things we would call intelligent — and machine learning is the technique the field now overwhelmingly uses to get there: instead of a programmer writing the rules, the system is handed examples and adjusts itself until its answers get better.

SiliconFlow closed new money on Sunday, and the interesting part is who signed: the same state system that buys its tokens is now taking equity in the meter. SiliconFlow has completed a second tranche of its B+ round and a C round, bringing its 2026 equity funding to nearly 2.

Two model stories where the interesting part is what the lab is willing to show: Google's internal math model runs on traces nobody has cleaned up, and StepFun finally put a date on open weights. An experimental Google model codenamed Mathematica has surfaced in leaked evaluation screenshots, and

Two stories where the ranking comes from outside the lab: China's biggest video platform just turned creator reviews into a live model leaderboard, and a clinical voice company published the first benchmark of whether AI can actually say a drug's name. Bilibili's new AI

Huawei Cloud used its annual conference to put a date on taking enterprise agents global — and to argue that the open-source edition is doing the selling. Huawei Cloud will make AgentArts, its commercial enterprise agent platform, available in markets outside China on December 30, the company said at HUAWEI
