AI’s climate impact is much smaller than many feared www.sciencedaily.com/releases/2025/… #AI #environment
Text Shot: New findings challenge the widespread belief that AI is an environmental villain. By analyzing U.S. economic data and AI usage across industries, researchers discovered that AI’s energy consumption—while significant locally—barely registers at national or global scales. Even more surprising, AI could help accelerate green technologies rather than hinder them.

this "claude made a c compiler thing" feels pretty dishonest and marketing-hype whenever you scroll to the very bottom to find these lines and the token cost lol i mean, sure its impressive (particularly that it was a fully offline environment), but seems like hype bait
The generated code is not very efficient. Even with all optimizations enabled, it outputs less efficient code than GCC with all optimizations disabled.
The Rust code quality is reasonable, but is nowhere near the quality of what an expert Rust programmer might produce.

Also good thing to keep in mind, that afaik the current "subscription token economy" is heavily subsidized and I am not sure Anthropic/OpenAI are charging necessarily full amount (i.e the same price that would charge for API cost)

ByteDance Seed's ConceptMoE: moving beyond uniform token-level processing to adaptive concept-level computation in LLMs! Why waste equal compute on trivially predictable tokens? When you can merge similar tokens into concepts while preserving fine-grained processing for complex content.

I did some experiments with nanochat and the SYNTH dataset from Pleias. I wanted to compare how a model pretrained with a mixture of SYNTH and FineWeb would compare to the standard FineWeb mixture. Results: Pretraining on Fineweb alone looks good (see below), but the story changes after midtraining:
Pretraining results for training on SYNTH + FineWeb vs FineWeb alone. 

Four rows are displayed: dgx1-continued, dgx1-synth-contued, dgx1-synth, and dgx1.

Rows labeled *-synth are trained with 3:1 SYNTH:FineWeb mixture. Results with *-continued* are trained for 3B tokens, 1B otherwise. CORE metric:

nanochat + SYNTH, 3B tokens: 0.147 CORE Metric
nanochat, 3B tokens: 0.166
nanochat + SYNTH, 1B tokens: 0.123
nanotchat, 3B tokens: 0.139

Been running comparisons nanochat pretrained on FineWebEdu vs synthetic data and it’s not looking great for the synthetic data runs thus far. We’ll see what it looks like after mid training

When Bill Clinton left office, we had a budget surplus. After 8 years of disastrous foreign interventions and tax cuts, we had deficit and a recession. Now with Trump we’re repeating repeating the same mistakes made under Bush

If you assume that there is an infinite number of tech workers with six figure salaries who want to live in the Bay or NY then the NIMBYs are right and no amount of new housing will help. But there is not an infinite number of tech workers, and the ones here are being laid off.

People talk about artificial intelligence but don't understand what that technology actually is, what the term "AI" is referring to, or best use cases for all the different tools that exist. Nor do they understand that they've already been using AI assistance for YEARS before LLMs became public.

All these things apply to a small percentage of AI research and companies, yet this website treats all AI models and research like it comes from xAI. You ran the actual open source and AI safety researchers off the app

Disappointing to see the president of my Alma mater reject DEI, especially given the racist incidents that marred my time there. Hopefully this rejection will be instructive for Santa Ono’s perspective on building an inclusive educational environment

The elephant in the room on social housing is that we severely lack the state capacity required to administer it at the levels required to bring down rents. And increasing state capacity is what’s explicitly being argued for in the Abundance agenda

I hear this myth all the time and it’s bizarre. Rich people hire property management companies to handle all the logistics for them and still get 90% of the rent each month. The idea that landlords are forgoing free money en masse makes no sense.

Someone should make a subscription service that makes it easier for middle aged men in their 40’s to blow up their lives. There could be a portal for boats to buy, red pill podcasts to follow, drugs to abuse, or people to have an affair with. Just a frictionless midlife crisis

Strongly endorsed. I don't care what Khalil said. What matters most here is the state punished him, without charge or trial, for speech. They disappeared him like in the sort of authoritarian country America used to criticize. Anyone adjudicating the content of his speech is missing the point.
