Some observations on Kimi:
1. It's a very good model! I don't think its performance can be explained away by distillation or anything like that. In agentic coding sessions, it seems pretty much on par with the best public models of Q1 2026. In my fairly limited use, it also seemed very token hungry. It's not obvious to me that this model is actually that cheap to run.
2. I am personally surprised the Chinese state continues to allow the open sourcing of models this good, given potential risks. To be clear, I *myself* might be fine with models presenting this level of marginal risk being open weight, but I am surprised that China is fine with it. I suspect the reason they are is 75% explained by strategic blindness/lack of AGI-pilledness (the CCP is very Yann Lecun-y in its views of AI). The other 25% or so is their lack of compute for customer inference (making China's open-weight strategy an unintended byproduct of US export controls) and the normal Chinese strategy of aggressive exports. For the companies, as opposed to the government, the decision to open source is partially ideological and partially because they are behind, and they know that very few people would pay for sub-frontier models from China.
3. Open-weight models are inherently decelerationist, and I'm continually surprised to see the so-called "accelerationists" so excited about open-weight models. I suspect the reason they are is that they know open-weight models are effectively ungovernable, and they simply like the overall cloak of ungovernability open-weight models create over the whole of AI. It's not a bad strategy; it reminds me of James Scott's recounting of the hill people in "the art of not being governed." Still, in the end, open-weight models deter further AI capex.
4. One probable outcome of an open-weight-model-dominant world is full AI communism, which is precisely what China proposes: rather than a market product, AI is a "public good" which will ultimately be provided by the state as a kind of "digital public infrastructure." This future strikes me as a dystopian hellscape, but I've never met an open-weight models advocate who doesn't ultimately concede this is where things end. You'd be surprised how many 'accelerationists' lobbied me, while I was in government, to support an eleven or twelve-figure federally funded data center so that startups could train models at a subsidy and then give them away for free. There was no other way for AI to progress, they said. Perhaps this is the logical end state of things. Nonetheless, I find myself surprised to see supposed accelerationists excited about such an outcome. I think many of them just don't know what they're doing. Many accelerationists do not view the creation and serving of frontier models as a legitimate business.
5. I would guess that the Trump Administration will at some point realize that their best strategy here would be to create large amounts of regulatory risk around the use of open-weight Chinese models. You don't need to "ban open source" (one of the dumber motifs of AI policy discussion). You just need to direct every agency to issue soft law that creates FUD. "A Federal Reserve Advisory Bulletin found that there may be backdoors in Chinese AI models." It needn't be that well justified. You just create enough regulatory risk that every regulated enterprise backs off. You probably don't want to create so much regulatory risk that you scare off the hyperscalers from serving Chinese models; this will just drive startups to sketchier providers. There's a happy middle ground here. I'd assume they will do some version of this.
6. It's probably true that open-weight models of this capability make the world a bit more dangerous, but not so much more that you'll really notice. At some point the models will be capable enough that you will notice. "A nonliving, invisible, dangerous, and infinitely self-replicating agent escaped from a Chinese lab," you say? Color me shocked.

A Brown professor gave his students a take-home midterm exam. After suspecting many cheated using AI, he made the final in-person. The orange dots are the midterm scores and the gray dots are the final scores. Looks like all but 3 cheated on the midterm.

I was wrong about the Midjourney ultra-sound scanner.
Well, maybe not wrong, but at a minimum I missed something obvious because I was thinking like a doctor who's been practicing for 25 years.
And I didn't explain my point well.
First, where I was wrong:
All historical precendent that showed that widespread screening imaging is net neutral or harmful was imaging that was expensive, inconvenient, gated by physicians and couldn't practically be repeated frequently short term.
If the Midjourney ultrasound is high resolution, harmless, inexpensive and convenient, people can get an initial scan, then if there are abnormalities concerning for cancer, they can get weekly follow up scans to see if it's growing/changing, and if it's not, they can leave it alone.
In retrospect, that is obvious but it never occurred to me.
Now, you'd assume that that approach would have to lead to it being useful and saving lives, and it probably will. But we won't really know it does until we have a couple years of data. Lots of things that seem obvious in medicine end up being wrong once we collect data.
Second, what I didn't explain well:
It's not that I think non-doctors are 'too dumb' to use the results effectively.
Its that historically it was literally impossible to use the results effectively, and that is super, super counterintuitive. It seems obvious that finding stuff early is beneficial, but experience has shown that it isn't.
Here's why:
The vast majority of abnormalities (i.e. possible cancer) isn't cancer - like over 90% of them, ends up being harmless - something thay your body could have handled on it's own.
But the only way to find out was to have invasive, risky procedures to biopsy or remove what was found.
And overall, the side effects from all the risky, invasive procedures to track down the over 90% of stuff that was harmless equal or outweigh the benefit from removing the less than 10% of stuff that wasn't harmless.
If the MIdjourney device can be repeated frequently, like weekly, at a low cost and is harmless, it could negate the need for the risky, invasive procedures.
Not saying it will, but it seems like it could and I confidently posted yesterday that it was a bad idea.
I was wrong to confidently post that.
I usually agree with Dr. Locasale.
But not on this.
A $100 full-body ultrasound on asymptomatic people, sold as a wellness service, will open a massive can of financial worms for individuals. You’ll pay around $100 for the scan, there’s a 90% chance they find something you’ll worry about, your insurance won’t cover the expensive follow-up they recommend, so you’ll be deciding whether to spend thousands to relieve anxiety about something with a 98% chance of being nothing.
How’d I get there?
Enough screening full body MRIs have been done to give us a good idea of the size of the can and what’ll be in it.
Roughly 90% of asymptomatic people who get a screening full body MRI have an abnormality. We have decades of diagnostic imaging with millions and millions of followed-up findings that allow 2/3 of those to be classified as incidental findings that definitely don’t need further work up.
Of the roughly 1/3 they can’t be sure about, after work up, 10% of them (4% of people who got a scan) end up with something important, and about 1.5% of people have a cancer detected.
And the existing evidence says finding those lesions doesn’t improve overall mortality. I know that’s hard to believe, but it’s true. Look up Korean thyroid ultrasounds or German melanoma screening.
Now extend it to a modality we have no baseline data on follow-up of lesions. Midjourney has been explicit that the early scans train the model and diagnostic accuracy comes later.
For the first year or two, it’s reasonable to say 90% of people who get a scan will have an abnormality they can’t rule out as concerning, and it’ll be up to the individual to pay to train Midjourney’s model.
Insurance probably won’t cover the follow-up scan or biopsy with an established modality, because there’s no evidence saying it needs follow-up.
So 90% of people who get scanned will be worried and facing the decision of whether to pay out of pocket for the expensive follow-up. A small percentage of those will have side effects and complications from the follow-up testing. And remember, 98% of the findings are nothing.
You can argue affluent people could get one, chase down all the abnormals, then repeat a scam (sorry, meant scan) every 3 months to look for changes. But that just leads to over-diagnosis with no mortality benefit.
So, rich people get scanned every 3 months with subsequent overtesting and overdiagnosis, normal people get anxious over things that are 98% likely to be fine, nobody has a survival benefit and Midjourney gets their model trained for free.
I wonder who’s coming out ahead here?

It simply was a no-brainer to this guy.
HOW I KNEW EPSTEIN WAS A FRAUD
A mathematician friend of mine was told by Epstein in 2004 that he made his money as a "mathematical option trader". My friend was impressed as Epstein had the largest mansion in Manhattan.
My option friends found no trace of him in the option markets; in the pre-electronic days it was impossible to have a size position w/o being traced (he needed size to make this kind of money). So I knew at 100% there was a scam.
Later was told that he was a "money manager". Again no footprint in the investment world. And supposedly his minimum size was 1 Bn. Impossible.
Epstein tried at several occasions to meet with me through two different people, after he served some jail time. I told them to tell him to fuck off.
So my only contact with him is through his reading of my books.

Five percent of patients account for HALF of healthcare spending, and the most expensive 1 percent account for TWENTY ONE PERCENT 🤯
This is one of the few things worth reading about the current healthcare debate.

I really like the term “context engineering” over prompt engineering.
It describes the core skill better: the art of providing all the context for the task to be plausibly solvable by the LLM.
