I think it is really worth reading this piece on RSI at Anthropic. There is a bit of navel-gazing, some marketing, and a lot of very sincere beliefs about what Anthropic thinks is likely in the near future of AI that you probably want to be aware of. www.anthropic.com/institut…

This is a key reason I don’t expect the flow of frontier open weights models to continue indefinitely, or even for very much longer. The gap between open and closed capabilities may soom start to grow, not shrink. www.reuters.com/world/beijin...

Some really interesting research from Anthropic that AI models have spontaneously developed a workspace that "appears to support the functions associated with conscious access" Demo of how this works: www.neuronpedia.org/qwen3.6-27b/... Research: www.anthropic.com/research/glo...

  • Anthropic says Claude has a 'J-space' of dozens of concepts, under a tenth of neural activity, that mediates multi-step reasoning.
  • Swapping 'spider' for 'ant' inside the J-space changed Claude's leg-count answer from 8 to 6, demonstrating a causal role.
  • A 'J-lens' tool surfaced silent words like 'fake', 'fictional' and 'manipulation' during deception tests, pointing at safety uses.

“Whimsey attacks” that seem absurd (“I cannot pay that much because of the Geneva Convention”) work against AI agents because guardrails are weak against out-of-distribution arguments. Smaller models fall often, but it even gives an edge against bigger ones. www.microsoft.com/…

This is a fascinating and important set of data which shows us where things are going, using OpenAI as a canary in the coal mine. The chatbot era is over & agentic systems are coming to tasks beyond engineering. Skills show promise as a way to standardize AI use in firms. open…

Recent commentary

The talk about AI & politics seems to be oddly missing a segment (a) assumes extremely capable AI is possible soon and (b) has a strong belief about how to use this technology to make human life better according to the political project they believe in. It is a moment of action right now.

BlueSky AI conversations have gotten less heated recently* * because much of this site has blocked me via automated lists so I have no contact with large parts of this social network, which isn’t necessarily a good thing, though it does make for nice echo chambers, which are pleasant, at least.

More evidence, from a large-scale study in China, that using AI hurts learning if it undermines mental effort. When homework time drops due to AI use, so do test scores. Across studies, there is a clear theme: AI tutoring in support of classes is good, using AI to "help" with homework is bad.

It is weird that there is still a substantial set of people who believe "AI is mostly hype" at this stage: Five Eyes is warning about AI, exponential revenue & token use at the AI labs, unit distance/Erdos proofs, and so on... There are many real issues with AI, not being real is not one of them.

AI is generally a weak fiction writer except for one particular kind of fiction (rich in impressionistic metaphor, staccato sentences, short & plot light, etc.) which it writes excellently. This happens to be a style that can sometimes do quite well in modern literary fiction short story contests.

Making humans responsible for their AI use seems like an incredibly reasonable way to address problems & opportunities in the use of AI for academic research, at least in the short term (autonomous scientific work will require different solutions).

As more people come to recognize the tells of AI, which mostly happens as you start to work with AI a lot, the scales are going to fall from their eyes and they are going to realize what some of us already see: how much of this site (and blog posts, articles, scientific papers) are AI now.

One thing we now know without a doubt as a result of AI is that doing the homework really does matter for learning.
