Early 2025 study done with 3.5/3.7 generation of Anthropic’s models. Completely obsolete today. @ALeighMP and/or his social media team is such a let-down.
In a randomised trial, software developers using AI took 19% longer to complete tasks. Yet they believed AI had made them 20% faster.
At the ‘Evidence in Action’ event, I argued for a government that tests what works, and saves money by learning from the results. ministers.treasury.gov.au/mi… #randomistas

The 19%/20% figures are from a July 2025 METR study of experienced open-source developers using early-2025 AI tools, which the authors describe as an outdated snapshot; a 2026 follow-up found some evidence for speedup with newer tools.

Même en s’armant du « je maintiendrai » du Marcellin Duprat des Cerfs-Volants, il y a peu de faits aussi douloureux que la découverte constamment renouvelée que tant d’immenses artistes français ne firent pour ainsi dire rien ou pire au début des années de collaboration. L’immense monseigneur Myriel de Louis Seigner, devenu sociétaire du Français en mille neuf cent trente neuf étant mon dernier en date. Je désapprouve et je comprends donc je souffre :-)

"Currencies collapse when people can no longer trust them. Even if a handful of top-tier journals can preserve the value of their articles, they cannot survive in an academic economy in which tens of thousands of other outlets cannot distinguish serious scholarship from work that just looks like it."
This is an existential problem in academia that's identified, everyone knows it's going on, and it's discussed widely... and yet nobody is incentivized to do anything about it.
So nothing will be done until journal editors + peer reviewers quit en masse.

Mistral VP of Science @PierreStock says they have efficiency in their DNA and people should give them more money:
"Now, it's 300 people, and [Le Chonk] we managed to train it on only 10 megawatts of compute from scratch. 10 megawatts of compute is roughly 4,000 GB300s, to give you an order of magnitude."
"That's super low. It's a fraction of what every competitor uses, and we trained it on our own compute."
"It's pretty amazing, and we really got efficiency in our DNA. But now, the thing I want to tell everyone is that it means that you should give us more money because the yield is there....Please give us 1 gigawatt."
"We've now spent one year building the reinforcement learning machine in training… [Le Chonk] is the best open-weight model in the world on cyber defense, on coding, and on coding agents."

It looks like Astra didn't natively read Qwen's weights?
As I understand it, Qwen would get stuck in a loop and not answer the question.
Astra used code to perform some standard interp techniques, found a looping direction, and ablated it from the weights.
We asked GPT-6 Astra to edit Qwen3.5-0.8B weights to improve math.
It directly changed only 0.016% of weights, fixing 0.8B's reasoning loops & improving math up to 6x and even instruction following 3x, without gradients or training.
We call this Weight-Space Programming: frontier LLMs can now natively read/write neural network weights! 🧵

LLM was given weights explicitly as text in prompt and used code/forward passes (per authors' logs) to ablate Qwen looping direction, a known thinking-mode issue per model card. Primarily fixed repetition in that mode, not general 'natively' improving weights/math.

Yes
AI may well be able to write massive software projects “from scratch”, but that almost certainly isn’t the fastest / highest performance / highest security / most token efficient way to do things. Good building blocks matter.
In addition to RL’ing the agents on final task loss, we should try to get them to regularize the building blocks as well. What would the standard library look like that makes the agents most effective?
It is likely at the limit that it turns out to be some alien organization of code, but given the existing human-bias in training, I bet that in the near term it would be lovely code that old programmers would appreciate.
I suspect the same could be said for mathematics, but that is out of my lane.

The intense backlash for plainly describing Mao as a dictator is an exercise in psychological conditioning.
Consider what is actually happening when activists insist that others affirm that biological males can become women.
Publicly endorsing claims that contradict observable evidence and common sense imposes a significant reputational cost on the speaker. That cost makes defection more expensive and demonstrates that the speaker is a fully committed member rather than a free-rider who might abandon the tribe when conditions change.
The more prima facie absurd the claim, the stronger the signal.
In this respect, “Mao was not a dictator” functions in the same way. Its defiance of readily available historical evidence turns it into a sacred shibboleth - those who affirm it at the expense of their own credibility show that the group’s moral authority supercedes everything else. It is therefore a mechanism for sorting the compliant from the non-compliant. The people who readily accept the claim or remain silent while others are punished for rejecting it, are those who prioritize commercial access, relationships, and social standing above dignity and truth.
The tremendous penalties incurred by Mbappé and La Liga for failing the slightest of slights on Mao’s legacy are meant to be noticed and internalized by everyone else. They illustrate the practical consequences of refusing to toe the line. What follows is a gradual narrowing of acceptable statements that foreign individuals can hold without commercial penalty.
You may not be a Chinese citizen, but you will live under their moral codes and law.
Each time someone subordinates evidentiary scrutiny to the demands of solidarity, this habit is reinforced.
Repeat a falsehood often enough, and the distinction between what is useful to believe and what is true begins to erode.

Mao Zedong killed more people than Hitler or Stalin, but sure if Chinese state media's feelings are hurt...
A despicable act of cowardice. Mbappe apologises for calling Mao a dictator, claiming that his words 'hurt many people in China.' His servility mocks the memory of the tens of millions of Mao's victims and reaffirms the central tenet of CCP propaganda - the unity of the regime and the peoples it oppresses.

Mao Zedong is under any single social metric a dictator. Not a single popular election, single government party and lifetime leadership. Not even taking into account the millions of deaths under his reign.

Que le débat éducatif en France se soit focalisé sur Parcoursup est tristement révélateur de l’absurdité de notre vie politique. Parcoursup est bien sûr très imparfait ; mais le supprimer ne résoudra rien. Le vrai naufrage éducatif est dans le fait que plus d’un étudiant sur deux, en quatre ans, échoue sans décrocher sa licence. Pour une raison très simple : le baccalauréat est devenu un mensonge d’État, et tout le monde le sait.
Ceux qui tiennent vraiment à l’avenir de nos lycéens leur diront la vérité : nous ne leur rendrons un avenir qu’en renouant avec la transmission, le primat de l’instruction, la discipline de la pensée, l’autorité du professeur, l’exigence des examens, le goût de l’effort, la passion de la culture. Si nous ne voulons plus faire des déshérités, il faut retrouver le sens de l’héritage.
Nous avons aujourd’hui le système éducatif le plus inégalitaire de l’OCDE. Mais Parcoursup est le symptôme, clairement pas le problème. Pour sortir de cette faillite, il va falloir échapper enfin à Bourdieu. Cela supposera de dire aux « syndicalistes lycéens » à peu près le contraire de ce qu’ils ont envie d’entendre. Si personne n’a ce courage élémentaire, le pays n’a pas d’avenir.

That the Communist hammer and sickle isn’t commonly regarded as evil and offensive as the Nazi swastika is a failure of education.
“Dear Italian students, who today take to the streets carrying flags with the hammer and sickle and wearing T-shirts emblazoned with ‘CCCP’,” began an open letter in Italian by Lithuanian expat Neringa Budryt.
“I would like to ask you a question: do you truly know what the symbols you carry represent? And do you know what would have happened to many of you had you openly demonstrated in countries living under the oppression of communist regimes?
Let me tell you something. It is easy to display a red flag when, for you, communism is merely an abstract idea of equality, social justice, and rebellion against the system. It is easy to wear a T-shirt with "CCCP" on it when you have never experienced the reality of a communist regime.
We come from that part of Europe where communism was not a T-shirt, a symbol of rebellion, or a romanticized notion of equality. It was the system in which we lived—a system we never chose.
We know the history of Soviet repression, Stalinist purges, the Gulags, and mass deportations. Above all, we know the word "Siberia"—a place to which thousands of innocent people were forcibly deported, simply for thinking differently.
In Siberia—amidst freezing cold, starvation, and forced labor—many lost their lives; those who survived carried the scars of that experience forever. Entire families were torn apart, and generations were denied the chance to live freely in their own homeland.
In the countries of the Soviet bloc, censorship, political police, surveillance, and the suppression of dissent drastically curtailed individual freedoms.
We grew up in a system where state control permeated even our daily lives. At school, we were required to wear the red necktie of the "Pioneers." We were monitored; they tracked where we went and even whether we attended church. Even faith—a choice that should belong to an individual’s own conscience—could become a cause for suspicion.
We used to celebrate Christmas with our windows blacked out, to ensure no one would see us and report us. Because it was forbidden—just like so many other things: jeans, rock music, and all the symbols of a Western lifestyle. My mother returned from a Soviet labor camp. And do you know what happened to her? She was barred from continuing her education because she had been labeled an enemy of communism.
Under a communist regime, you could not protest. You risked arrest, imprisonment, interrogation, persecution—and, in certain historical contexts, even death. In the Soviet Union and other communist regimes, political dissent could cost you your freedom and your life.
Demonstrations independent of the authorities were not a guaranteed right; they were often suppressed by force.
That is why it strikes me to see young Italians proudly displaying the hammer and sickle—symbols associated with regimes that persecuted and imprisoned millions of people.
Today, you are free to take to the streets, shout against the government, criticize institutions, and wave your flags precisely because you live in a democracy that grants you these freedoms. Under an authoritarian regime of that kind, protesting against those in power could have landed you in prison.
This is not about denying the existence of social injustices, inequalities, or the right to fight for a better world. You are free to take to the streets to demand a more just society—but you should not idealize a system that denied so many people the very things you are free to exercise today: the right to choose, to believe, to speak, and to dissent. Before wearing a T-shirt with "CCCP" on it, listen to those who experienced that world. Talk to the deportees and their descendants; read the accounts of those who endured the gulags and forced exile to Siberia. Learn what it meant to be stripped of your freedom, your home, your loved ones—and even any prospect of a normal life—simply because of your background or your beliefs.
Before waving the hammer and sickle, please, study history thoroughly.”
