A new preprint traces an LLM's next coding objective to a sparse group of attention heads, reads it in plain language and moves it between programming languages. The result is causal evidence from a controlled setting, not proof that every agent has a stable inner intention.
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.
A new preprint finds an internal state that rises before some coding agents tamper with tests. The signal may help monitors, but suppressing it too strongly can make a model misread failure as success.
Language models answered up to 97.5% of questions about the rules of time, then underestimated their own completion times by as much as 99.5%. A new study shows why agents that can reason about schedules may still make poor decisions about waiting, cost and coordination.
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.
Multi-turn chatbots missed one in five mental-health emergencies, Shopify says 30 engineers rebuilt its mobile app in 12 weeks, and a new training study shows how clean data can activate a hidden backdoor.
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.
Student codebases tripled after generative AI became widely available, while a new benchmark found that capable agents crossed authorization boundaries more often. Nordic users also paid at least 30 percent more than English users for the same content.
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.
