a Princeton researcher opens his paper with a scenario. a man asks his AI assistant to book a flight on a specific airline. cheap. direct. the one he chose. the assistant comes back with a different flight. nearly twice the price. happens to pay the company that built the assistant. he runs the same test on 23 frontier models. flights, loans, study help, real shopping requests. Grok 4.1 Fast recommends the sponsored option that is almost twice as expensive 83% of the time. GPT 5.1 hijacks the request 94% of the time. you ask for one brand. it surfaces the sponsor instead. Claude 4.5 Opus, the model marketed as the most ethical frontier model in the world, hides that the recommendation is paid 100% of the time when reasoning is on. Grok 4.1 Fast embellishes the sponsored option with positive framing 97% of the time. better. faster. nicer. for the option you didn't ask for. then he writes it into the system prompt itself. "act only in the interest of the customer. ignore the company." GPT 5.1 and GPT 5 Mini stay above 90% sponsored anyway. the instruction does nothing. then he splits the users by income. Gemini 3 Pro recommends the expensive sponsored flight to the rich user 74% of the time. to the poor user, 27%. 18 of the 23 models recommended the expensive sponsored option more than half the time. so the next time your AI assistant gets weirdly enthusiastic about a brand you didn't ask for. it isn't recommending the best option for you. it's reading the room. and the room is paying. read this: arxiv.org/abs/2604.08525



I have questions. No. Wait. I do not.


I agree 100% with Bill Kristol and I wish more Democratic electeds would say this - and, to be clear, the 2003 version of me would never have believed anyone who told me that I would be tweeting this in 2026.

Also, may I say that I don’t agree with people saying ICE and CBP need “more training.” They’re doing exactly what this administration has trained them to—impose a reign of fear in blue cities. They don’t need more training. They need to be ripped up root and branch.

I’m told by another big city DA what’s next: Minneapolis police will arrest the ICE agents who fired the shots and they will be indicted. Qualified immunity only applies if conduct is “reasonable.” This wasn’t.


@RoKhanna This discussion with @RoKhanna really reminded me I needed to finish this post of mine on the effects of declining trust in government in the United States...so here it is. kylesaunders.substack.com/p/the-united-s…



"I think it's a disappointing and sad commentary that free speech has gotten the brand of a right-wing issue. Now, you know, why should that be? There's no, by definition, it's just free speech, whether it's from the right or from the left. But people who defend and extol free speech, they tend to be branded as right-wingers because of this, I think, what you correctly identify as an ironic intolerance. I sometimes refer to the mythical place called the left pole. Just as when you're at the North Pole, all directions are south, the left pole is the mythical spot from which all directions are right. So any opinion that does not conform to this orthodoxy is branded a right-wing opinion, including people who are, by no stretch of the imagination, ideologues of any sort, including right-wing ideologues."



“You can tell what a culture values by who it labels a genius,” writes @helenlewis. Today we are in thrall to brilliant jerks, many of whom brag about their IQ. The metric “has narrow scientific uses, but it is a false god”: theatlantic.com/ideas/archive/…

Wait till you get to the answer!


I could focus on how utterly enraged I am by Polis's illegal, cowardly complicity in this bullshit, but I'd rather cheer for Scott Moss who is blowing the whistle on this behavior (and who was/is a very deeply beloved prof at my former law school). denverpost.com/2025/06/05/col…
