The Stack
Robots normally need thousands of teleoperated practice runs to learn a single job. Today two stories pointed the other way — a foundation model that learns by watching once, and a European startup betting €28 million that the transformer is not the end of the story. Skild AI's new

The Navier-Stokes credit fight has produced a second, quieter accusation — and it may matter more than the first. Mathematician Andreas Thom says OpenAI gave him a misleading answer about whether his private work fed its models. After OpenAI announced a result on the non-sofic group problem — work built
The Frontier
Coding agents stopped being a two-horse race today. Cognition has launched SWE-2, the model behind Devin, and by its own published numbers it lands closer to the frontier than any release in the company's history — while undercutting the models it trails on cost. On the FrontierCode

The world's largest record company has stopped treating AI music companies purely as defendants — it just handed one of them a license to its catalog. Universal Music Group and ElevenLabs have signed a multi-year strategic agreement — ElevenLabs' first with a major label — that starts with a

Two OpenAI announcements landed within minutes of each other this afternoon: a government-wide procurement deal that waives the license fee entirely, and a data-analysis agent aimed at every company that already pays someone to build dashboards. OpenAI and the General Services Administration signed a 27-month OneGov agreement
The Everyday
AI made filing a complaint nearly free, and public systems built on friction are now finding out what that does to their workload. Plus: a $1 billion bet on taking data centers off the grid, and a robotics startup stepping out of stealth with $100 million — and robots already on

Amazon spent twelve months walling its catalog off from AI platforms — crawler blocks, a court order against Perplexity's shopping agent, product feeds cut from Google Shopping. On Thursday it announced the thing all that blocking was quietly building toward: its advertisers can now run ads inside ChatGPT. The

A chip startup raises a massive round on the thesis that commodity memory can outpace HBM for running AI models, and a warehouse robotics company finally steps out of the shadows. Positron AI raised $875 million in a Series C round at a $5 billion valuation, doubling down on a

Two days after former Anthropic pretraining researcher Jacob Coxon posted a viral warning that AI "could kill us all by the end of the decade," the fallout has moved from social media to Capitol Hill — and bipartisan legislation is already on the table. Coxon's warning has

Two moves this afternoon that say the same thing from opposite ends of the stack: AI is where the money and the compute are heading next. Amazon is letting its advertisers buy inventory inside ChatGPT, and Qualcomm is rebuilding its phone silicon around agents that never phone home. Amazon is

Two stories dominated the afternoon: a state that finally built the verification layer everyone has been asking for, and a federal space agency handing the Moon to the open-source community. Plus, a DeepSeek release aimed squarely at the agent cost curve. California now has the country's first

Sber's GigaChat team has open-weighted a 432-billion-parameter reasoning model under an MIT licence, and the numbers put it within touching distance of DeepSeek V4 Flash. GigaChat 3.5 Reasoning runs 28 billion active parameters, trains natively in FP8, and mixes multi-head latent attention with
