Fresh on the arXiv: @booleananalysis.bsky.social, Kewen Wu, and I present new classical algorithms for the Short Integer Solution problem (under infinity norm) that outperform the elegant Chen-Liu-Zhandry quantum algorithm, showing that there is no exponential quantum speed up anymore.

We are starting to see some nuanced discussions of what it means to work with advanced AI in its current state

In this case, GPT-5 Pro was able to do novel math, but only when guided by a math professor (though the paper also noted the speed of advance since GPT-4)

The reflection is worth reading.

(In case you hadn't been following, the environmental impact of current AI models is now much lower, generating 100,000 words with AI uses less power than watching Netflix for 45 minutes on your TV)

If you haven't done this with o3, you haven't really seen what these models can do.

This is one of the most-shared posts on Bluesky in the past day and it's just completely false. You might think ChatGPT is a *bad* search engine, or prefer another search engine. But it has had integrated web search since last year.

"o3, You are a consultant hired by the Dark Lord, analyze the org chart of Mordor. How would you improve it for today's changing Middle Earth"

o3 does some actual satire, ending with: “One Org to rule them all, One Org to find them, One Org to bring them all, And in the darkness, align them.”

For years I've been throwing the same puzzle challenge at new GPT models. Every one has failed, until now.

This was fun: "o1, build a simulator of a D&D guild hall. Persistent characters come in, get quests, interact with each other, leave & return, make it procedurally generated"

I kept asking it to add other ideas (relationships, etc) 8 times, got no errors, just worked each time. Desire-based coding!

The NIH overhead cut doesn't just hurt universities.

It's deadly to the US economy.

The US is a world leader in tech due to the ecosystem that NIH and NSF propel. It drives innovation for tech transfer, creates a highly-skilled sci/tech workforce, and fosters academic/industry crossfertilization.
2. While NSF and NIH indeed have a mission to fund specific research innovations via grantmaking, they do a lot more than that.

Their principal role is support a scientific ecosystem in the United States, that includes everything from education and training to infrastructure and communication.

OpenAI’s deep research is very good. Unlike Google’s version, which is mostly a good summarizer of many sources, OpenAI is more like engaging an opinionated (often almost PhD-level!) researcher who follows lead.

Look at how it hunts down a concept in the literature (& works around problems)

In all seriousness how batshit is it that a Chinese AI bot is censoring a book THAT HASN'T EVEN BEEN PUBLISHED YET. What dystopia are we all living in.
🤐 DeepSeek doesn't like our graphic novel, YOU MUST TAKE PART IN REVOLUTION — which isn't even out until March 4th! So... ya'll should go out and pre-order the comic, right?! Fight the censorship! Join @badiucao.bsky.social and I in the revolution! 😆 Order here: melissachan.com/revolution

this post is trending in my feed but it does not make sense. i don't see any reasonable interpretation by which DeepSeek demonstrate that model scaling is not the best way to develop AI. their model is very large, and their training corpus is very large. they were just scaling more efficiently.
Much of the coverage has been focused on US-China tech competition. That misses a bigger story: DeepSeek has demonstrated that scaling up AI models relentlessly, a paradigm OpenAI introduced & champions, is not the only, and far from the best, way to develop AI. 3/

No.

See: cloud.google.com/sustainabili...

www.gstatic.com/gumdrop/sust... has info about our net zero goals (which are goals for the year 2030 that we are working towards). p.30: "We maintained 64% carbonfree energy, on average, across every grid where we operate." (for 2023).

Sharks are older than the rings of Saturn.

This paper finds that the rings are no older than 400M years. Sharks date back to at least the Late Ordovician Period, 450M years ago.
