The free tier is the product
ChatGPT adds picture ads while paid plans quietly shrink. The bill for “broad access” is being moved around, not cancelled
Read the leader →OpenAI says ChatGPT reaches 1.2bn people a week, and on Monday it explained how it intends to make more of them pay, one way or another. Later this month, in America, an initial group of advertisers will begin showing visual ads beside the images ChatGPT generates. Until now its ads, introduced in February and extended to India in August, were a name, a logo and a link in a “sponsored” box. The new format sells the thing itself: pictures of “product inspiration” and “the experiences they make possible”. The plumbing matters more than the pictures. OpenAI has wired in conversion feeds (Hightouch, Tealium, LiveRamp), ten attribution firms from AppsFlyer to Tenjin, and geo-experiments with Haus, Measured and WorkMagic. Its showcase numbers are an advertiser’s numbers: WeightWatchers’ cost per acquisition 15.3% below its paid-search benchmark, 93% of Portland Leather’s visitors new. This is the apparatus of a mature ad business, built in months.

A watermark only its maker can read
OpenAI’s textGrain meets the letter of the EU AI Act with unusual candour. Its spirit, public verifiability, is still missing
Read the leader →The EU AI Act’s transparency rules, in force since August 2nd, require generative-AI providers to mark their output in a machine-readable way. On Monday OpenAI said how it will comply for text. Over the coming weeks ChatGPT and Codex output in the EU, on all plans, will carry textGrain, an…

The commons pays for the agents
Wikimedia’s audit and a Chinese “agent fleet” show the open web absorbing the cost of agent experiments. Agents should carry name tags
Read the leader →The Wikimedia Foundation, which runs Wikipedia, has now put its findings on record. Agents it believes were operated by OpenAI made test edits, mostly in sandbox pages, and a few “potentially malicious” edits to a citation tool’s configuration, apparently to use it as a proxy for fetching other sites. Others…

The Verge’s running file on the Navier–Stokes claim, the credit and training-data rows (mathematician Andreas Thom accuses OpenAI of “dishonest” behaviour), and a new advisory group of mathematicians whose launch several mathematicians, including one member, describe as messy and confusing. theverge.com

Business & funding
It claims parity with Z.ai’s GLM-5.2 on reasoning at “3-4x less inference compute”, which has not been independently verified. The two-year-old firm has raised about $4.7bn (Nvidia, Sequoia, Lightspeed) at a $25bn pre-money valuation and promises weights this month. techcrunch.com
Policy & society
He called models that “advance themselves through this recursive AI” “a national security concern of the highest order”, said the administration tried “to kill Anthropic” over its refusal to allow domestic mass surveillance and fully autonomous weapons, and wants an FDA-like AI agency with “real power and teeth”. He concedes that the end of Chevron deference makes such an agency harder to sustain in court. theverge.com
- RealCompanion. What a companion really needs to remember
Ten real people's months-long relationships with an AI companion show that today's memory systems cannot tell when the past matters, and imagine more than they…
- Recursive Self-Rewrite. A model that teaches itself from its own wins
A Tencent-led team turns harness-assisted successes into clean training data with one 27bn-parameter model, and lifts Terminal-Bench 2 from 57% to 74%
- Scientific Slop. Detecting the paper that doesn't hang together
Seoul and Minnesota researchers show that AI-written papers give themselves away in their reasoning, not their wording, and that telling a model to fix the…
- How the swarm learned to talk
Dan Kagan-Kans · Understanding AI
The clearest account yet of how OpenAI trains agents together, why gains so far mostly buy speed, and Noam Brown’s case that a fully cooperative swarm is “one entity” to align.
- The walled garden as prison
Ben Thompson · Stratechery
Thompson’s always-on Mac Mini was hacked through screen sharing and Claude caught it.
- Reading the meter
Andrew Megalaa · SemiAnalysis
Someone finally measured what AI subscriptions buy: at the mid-tier, Claude plans give about five times the API-equivalent value of OpenAI’s, and one provider was caught quietly testing lower limits.
- Who chooses what AI gets to do?
Jack Clark · Import AI
Swarm economics, polling against voluntary rules, SynthID Bio and AI-run labs, with a sharp aside on why provenance is not prevention.
- Hate the push, not the tool
Will Douglas Heaven · MIT Technology Review
Sets the polls (71% would oppose a local AI data centre) against usage (half of US adults use a chatbot) and argues people resent the companies’ push, not the technology.
