Will “The Lean proof that OpenAI provided isn’t the same as their printed proof, so who knows if any of it is actually right” get as much publicity as the original PR, I wonder. The final 20% is 80% of the work. Whether it’s a website, a Photoshop knock-off, or a Millennium prize problem
Example 3.1 (The NL paper claims a stronger inverse estimate than the cited Lean formalisation). Figure 3 concerns the estimate in Lemma 8.6, equation (8.19), of OpenAI’s Finite time blowup for Navier–Stokes. We compare this estimate with the cited Lean declarations at commit f9e8bc5 (click to see the documentation on Github). The issue is a change in the order of the input derivatives required to bound the output derivatives. In particular, we have the following discrepancy. With m a nonnegative integer, the comparison in Figure 3 is
NL paper, equation (8.19): ∥N−1F∥Cmy ⩽ Cm∥F∥Cm+4y, (3.1)
Lean Estimate: ∥N−1F∥Cmy ⩽ Km∥F∥Cm+5y. (3.2)
Summary: The Lean code produced by OpenAI often has stronger conditions on bounds on the derivatives of various functions than the corresponding results in the NL paper.

Sometimes my wife and I like to send each other text messages as though they’re democratic fundraising messages, and I believe she has produced the jewel of the form.
, it's
and I
have some personal news to share with you.
Being a mom is one of the greatest joys of my life, and I feel deeply that we should have salad tonight
This year has been challenging in many ways, and I have immense gratitude for the kindness and support of family, community, and people like you who have continued to stand by me through everything. It means the world, and I wanted you to be among the first to know that squash is in the oven and kale is in the fridge.As many of you are aware, ve been navigating one of the most challenging periods of my day while waiting for dinner.
Facing baseless federal hunger brought on by not eating since lunch, fighting for the working kids of this country, and now caring for a mean toddler and helping him grow up in a world that isn't always easy. But it has also reminded me exactly why I do this work and who I do it for.
I will never stop working to eat dinner. I will never stop fighting for what is right, even when there is also some feta in the fridge. And I will never stop being so very thankful that you are by my side in this important work and that there is tahini in the pantry for dressing
With love and gratitude,
stop to end

Y'all know Bean Soup Theory? How someone can post a recipe for bean soup and the replies will be "BUT WHAT IF I DON'T LIKE BEANS?!" That is sometimes annoying trolling but it's predominantly people failing to understand how to read for context, understand intended audience, etc.

The world's most notorious custard-pie thrower is dead. What an obituary. He got Bernard-Henri Lévy seven times.
​Known to his army of fans as L’Entarteur or Georges le Gloupier, Godin launched his career as a serial deflator of egos in 1969, when he planted a tarte à la crème on the face of the French novelist Marguerite Duras (“She has a kind of intelligence and cleverness that serves only her own vanity,” he complained), and he went on to “pie” a cast list of celebrities for sins ranging from pomposity to “choosing to function in the service of the capitalist status quo”.The same could not be said of Bernard-Henri Lévy, one of France’s “new philosophers,” whose provocative views on sex, frequent appearances on television and penchant for white silk shirts unbuttoned practically to the navel, had made him a cult figure – and one of Godin’s most satisfying victims.

Levy once declared: “I am the most gifted writer of my generation,” and often boasted of his reasonableness and tolerance, but he was forced to endure footage being repeatedly shown on French television of himself, covered in cream, during a visit to the Belgian city of Liège, trying to strangle Godin and shouting: “Get up, or I’ll kick your head in.”Noël Godin was born on September 13 1945 and came to pie-throwing after a rebellious youth in which he scandalised the priests in the confessional by speaking of his “horrible sexual life”, and was thrown out of Liège University after emptying a pot of glue over the head of a law lecturer who had helped write the constitution for the Portuguese dictator António de Oliveira Salazar.

He found work at Friends of Film, an obscure magazine published by the Belgian Catholic League. It had a tiny readership, which was just as well, as Godin made up most of his articles. In one he claimed that Louis Armstrong had once been a cannibal and had invested in a film called The Vegetables of Good Will in which Claudia Cardinale played a giant endive.

In another he conjured up a fictional blind Thai filmmaker named Vivian Pei, describing her film, The Lotus Flower Will Never Again Grow on the Edge of Your Island, in such convincing terms that an Asian film specialist travelled to Thailand in an effort to track her down.“We’re very careful not to hurt people,’’ he explained. “Well, they are hurt, but always in their amour-propre.”

In 1995 Godin published an autobiography, Cream and Punishment. His other targets over the years included the New Wave director Jean-Luc Godard (who charmed his assailant by hailing the attack as a homage to silent film), the French politician Nicolas Sarkozy, the choreographer Maurice Béjart and the Ryanair chairman Michael O​’Leary. He tended not to pick Belgian victims, he explained, because few would notice if he did.

Things To Do With Potatoes Throw a potato on the ground behind a stranger, then say "Excuse me, you've dropped your potato!". If they deny ownership, pull another potato from your pocket, saying "Well it's definitely not my one". Hide a potato in a pair of shoes at a bowling alley.

His argument is basically: 1. For each word choice, LLMs pick the best word, subject to temperature. 2. Watermarking therefore makes it pick worse words. 3. Therefore the writing is worse. 4. Fuck the EU.
