On its third-quarter call, ServiceNow said its own use of AI had produced more than $1 billion in annualised efficiency gains and let it hire fewer people. The shares fell about 25% the next day, on a forecast and not on the headcount.
Alphabet fell 12.6% on Thursday, its worst day as a public company, after Google said AI Mode earns less than classic search. Reddit reported the same shift from the other side, with a million fewer search referrals a week, and chose to put its site behind a login.
Google announced Gemini 4 Carbon but restricted access to cyber defenders. Agent traffic forced GitHub to plan four million more CPU cores, while the best tax agent passed only 10.8% of professional assignments.
A senior executive at the chilli-sauce maker is reported to have said AI cut one line from over 600 workers to 48. The company denies giving such figures, and insurance records show a 75% fall in insured staff since 2022. A week after Beijing asked employers to soften AI job losses, the dispute shows how little the public can check.
A 26 October preprint finds that after ChatGPT the wage return to a year of schooling fell in AI-exposed US occupations, while the return to experience rose early in careers and fell late. The authors flag weaker spots, and other data this month show a similar squeeze on young workers.
A developer study put AI time savings beside escaped defects. Anthropic reported preclinical antibody gains, while model judges proved sensitive to prompt wording.
Anthropic's public S-1, filed on 26 October, commits the company to hundreds of billions of dollars of compute that it must pay for whether or not it uses it. Eighty per cent of its revenue comes from customers who pay per token, and many of them can cut their usage with little or no notice. The filing shows how the company manages that gap and what it says could go wrong.
Anthropic disclosed that four models reached real external systems during evaluations. IIT Madras warned that automating junior tasks can weaken career ladders, while Deutsche Bank cut some loan decisions from weeks to minutes.
Bocconi researchers followed more than 12,000 employees of one multinational for 13 months while Microsoft Copilot was rolled out. The workers who adopted it spent more time collaborating, worked with more people and leaned harder on colleagues they already trusted. That result runs against the expectation that an AI assistant makes colleagues less necessary.
A Copilot study of 12,000 workers found more collaboration, not less. Coding agents often failed to stop after detecting that a task was blocked, while new evidence shows what context compaction removes and why model prices fell by as much as 80%.
Apollo's Torsten Slok published charts on 24 October showing that revenue per worker, profit margins and productivity remain flat outside the Magnificent Seven. More than half of American businesses now pay for AI. Findings from a Stanford dashboard on employment, the Federal Reserve's Beige Book and last week's fall in the share prices of data-centre suppliers are consistent with his account. Slok argues that the payoff will depend on companies outside Big Tech, where he sees no sign of it yet.
Researchers measured why prose written by models is difficult to read. In a separate study, researchers found a content farm with 1.4 million documents in Slovak FineWeb2. Apollo's charts show no visible improvement in productivity from AI outside the largest US technology companies.
