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.

@notrobbyboose maybe he has a bigger calling in his life than to continue a hobby that incentivizes him to interact with people like you

It's been a hell of a ride, but it's time for me to take a step back from @The200Level. #Illini

@PrestonPysh Learned a ton from you and appreciate all the positive contributions to the space. Wishing the best to you and your family.

A personal note. After years of public discussion/work: the podcast, social media, venture capital, everything — I'm stepping back to focus on my family.
My kids are growing fast. My wife deserves the best of me. To everyone who listened, read, grew, and built alongside me — thank you. What a blessing you all have been!

@APompliano Absolutely a courageous and heroic act. Since this keeps happening, we could also make his important job even easier by outlawing ability to purchase weapons designed to annihilate herds of elephants from local Walmarts.

@FanboyCarp @The200Level Congrats again Carp! Can’t wait to read and relive some of those childhood memories with you

@cryptobitsBTC @rajatsoni That’s a $1.3B purchase. JD would have to sell a lot more JPM stock than that. Also, who is filling a 26,000 btc order? Lol

@bitcoinzay Kobe is a career 14-56 on game winning field goal attempts (25 percent). A Cam Reddish wide open corner 3 in rhythm is a higher percentage shot.

This is why Kobe and MJ are the best
The “right play” is a two dribble pull up from 15ft that you practiced for years

It’s a beautiful fall Saturday. I’m breaking in my new Pit Boss Smoker and ready to enjoy some decent college football.
So, I’ll save the pod until tomorrow. And I want to hear from you.
ONE WORD to describe how you’re feeling about the future of #Illini football under Bielema.
The 200 Level: A Fighting Illini Fan Podcast@The200Level
We’ll save the podcast for Sunday, but it’s worth asking #Illini fans: In one word, describe how you’re feeling about the future of the program under Bret Bielema. Responses will be read on Sunday’s podcast!

@ChipotleTweets no cattle were harmed in the making of my steak burrito. Thank you for finessing me again.

@papicurbelo11 If I wanted to get my mom a turnover for Mother’s Day, I’d go to a bakery.

@Jumpshot8 Why we need analytics 1) Bogy 2pt fg percentage is only 7 PP higher than his 3PP 2) Finney-Smith would 100% still have met him at rim to contest 3) 2 only sends game to OT. In sum, wide open corner 3 to win is mathematically much better shot
English

Now you people know why I rip analytics. Wide open straight line drive for 2 to tie game at home in an elimination game and he steps back for a 3. Are you freaking kidding me? What a joke !!!! This is what’s wrong with our game. Yea a 3 is worth more than a 2 #NBAPlayoffs

@thetrocro @tedcruz Ted understands bitcoin value prop. However, the hypocrisy of him acting like he’s anti authoritarian when he never batted a lash supporting Trump’s antics for four years gives him no credibility.

Can't believe I'm retweeting @tedcruz, but such is our world. Everything he says here is true.
