A Carnegie Mellon and Berkeley preprint prices the months a data centre stands idle while it waits for electricity, and finds that off-grid solar with batteries wins in 85% of the continental US even though it is rarely the cheapest source per kilowatt-hour. Anthropic's search for a gas supply chief shows the other bet, and the model's limits show where it could fail.
Users rated a more accurate assistant less favourably than agreeable ones. Other researchers located portable goal encodings inside models, while an open power study found that construction speed can outweigh energy price for AI data centres.
A peer-reviewed study found that households paid 62% of grid costs linked to data-centre growth. Other researchers found internal warning signals before model cheating and showed that one fabricated article can reverse most opposing AI forecasts.
Indeed's third-quarter tech report finds job postings up in every tech category and software pay growth nearly doubled, in the profession most often named as the next to be replaced by AI. Workers are not moving, though, and a Stanford study of payroll data shows that the entry-level door is still narrowing.
Coding agents copied vulnerabilities from repository context, while language models underestimated their own run time by as much as 99.5%. CoreWeave also raised GPU-cloud prices as short contracts passed $40 million per megawatt a year.
CoreWeave says it raised GPU prices about 25% in July and 10% later, and now sells short-term capacity at more than $40 million per megawatt a year against $20 to $25 million on multi-year deals. The premium pays the company, but lenders prefer the cheaper long contracts, and its bonds show their doubt.
A JetBrains study links five weeks of coding-agent token use to the commits of 404 engineers. Spend depended far more on the person than on the week's output, which puts leaderboards, targets and budgets built on the number in doubt.
A field study linked AI adoption by small online sellers to 51.6 percent higher monthly sales, while two studies found that agent oversight improves when people inspect actions and require measurements before completion claims.
Anthropic lowered the price of Claude Fable 5.2 by a fifth, yet an independent index measured the highest cost per task of 73 models at maximum effort. The gap comes down to how many tokens the model spends, and Anthropic's own charts say the effort setting decides it.
Claude Code approval rules exposed secrets in 1,122 public files. Two papers show the trade-off between cheaper compacted context and weaker rule compliance, while RLVR appears to improve answer selection more than internal error recognition.
Census data analysed by the Mercatus Center show new business registrations without hiring signals rising 26.8% in AI-exposed sectors since early 2024, while those that look like future employers fell 6.4%. The author says the finding is descriptive, not causal, and the debate over what it means has only started.
The Bank of England estimates AI added about 0.5% to UK productivity over three years, open Chinese cyber models approach gated US performance at a fraction of the token cost, and matched model answers hide different future belief updates.
