Este artículo me ha parecido muy provocador y me ha abierto muchas dudas. Quizá un feminismo plural y dialogante pueda tener conversaciones incómodas y constructivas con una fracción de los hombres objetivo del discurso manosférico, pero temo que para los propios manosféricos ya sea tarde para eso
"La masculinidad se ha convertido en una fuente de gran sufrimiento, tanto para hombres como para mujeres. Entender esto no es sólo comprender su crisis global, sino también vislumbrar una posibilidad de solución"

A big AI question is why, as LLMs get bigger, their values seem to increasingly converge on the same preferences, this holds for Musk’s Grok & China’s DeepSeek, too.

Ok, time for a short thread about this paper.
My sense over the past six months or so is that chain-of-thought prompting as used in e.g. ChatGPT o.3 improves substantially upon previous systems such as ChatGPT 4.o, at least for certain tasks.
But how revolutionary is it?

If I have time I'll put together a more detailed thread tomorrow, but for now, I think this new paper about limitations of Chain-of-Thought models could be quite important. Worth a look if you're interested in these sorts of things.

I just don’t see signs of a major increase in hallucination rates for recent models, or for reasoners overall,
in the data.
It seems like some models do better than others, but many of the recent models have the lowest hallucination rates.

A controversial study where LLMs tried to persuade users on Reddit found that: “Notably, all our treatments surpass human performance substantially, achieving persuasive rates between three and six times higher than the human baseline.”

And this applies to so many other approaches, like building-my-own-RAG...
The fast evolution of AIs makes it risky to spend tons of effort getting around current model limits through clever approaches, rather than waiting.
I trained a LoRA 6 months ago to get an image of a Wired Magazine cover, now I can just ask GPT-4o to make it.
Wonder if this was a trap for Apple.
