This sounds more or less unavoidable? Decompilers are inherently security-sensitive. If you take avoiding cyberattack uplift seriously as a goal, I don't see how you get around essentially refusing to work on them.

Obviously there are plenty of innocuous applications too, but it's not like the people building decompilers for nefarious reasons will be explicit about it. The LLM abstraction just inherently doesn't have enough context to distinguish your intentions or your broader use cases. This is why both Anthropic and OpenAI have had to create side channel mechanisms for security researchers to establish a trusted use context. It sounds like this makes this not a viable product for you, unfortunately, and it makes sense that that's frustrating. But I also don't see what different behavior one could reasonably expect given the constraints.

If it's any consolation, these restrictions only make sense for models that are ahead of the open-weights frontier, so open-source hackers will presumably get Mythos-level capabilities in the relatively near future anyway.

The KV cache consists of activation vectors for every attention head at every layer of the model for every token, so it gets quite large. ChatGPT also estimates 60-100GB for full token context of an Opus-sized model:

It's true that these are very different activities, but I think most ML researchers would agree that it's actually the creation of ImageNet that sparked the deep learning revolution. CNNs were not a novel method in 2012; the novelty was having a dataset big and sophisticated enough that it was actually possible to learn a good vision model from without needing to hand-engineer all the parts. Fei-fei saw this years in advance and invested a lot of time and career capital setting up the conditions for the bitter lesson to kick in. Building the dataset was 'easy' in a technical sense, but knowing that a big dataset was what the field needed, and staking her career on it when no one else was doing or valuing this kind of work, was her unique contribution, and took quite a bit of both insight and courage.

There actually has been some recent work on digitizing smell, most notably Osmo, which was founded by some ex-Google ML researchers: https://www.salon.com/2025/01/05/digital-smell-has-arrived-a...

Even if you charge $10/hr, or whatever the market rate would be for street parking spots, you still need an enforcement mechanism to prevent people overstaying.

In general, the idea of a "market rate" for any given property depends fundamentally on a system of property rights actually being enforced.

Senators, especially committee chairmen, have quite a bit of implicit leverage, beyond the direct leverage of subpoenas or directly cutting funding to an offending agency.

Any given Senator is to some extent constantly in a favor-trading game with executive branch officials. People from the President on down need congressional cooperation to get their pet provisions into bills, programs funded, nominees approved, etc. A Senator can tell a White House official "I'd love to help you with that, however I have this issue with this agency not responding to my requests". Assuming it's a reasonable thing, whoever at the agency is in charge of this then gets an irate call from their boss's boss's boss ordering them to cooperate.

Of course this mostly doesn't actually get played out, because everyone understands the dynamic that defying senatorial requests will ultimately cost the President in terms of cooperation on other issues. So the norm is mostly to comply with reasonable requests, unless you're quite sure that it's a top-level priority where the White House really wants to take a stand.

If you enjoyed this article then you must watch the A Capella Science music video on the same subject:

By far the catchiest song about eel mating you will encounter today.

The public interest is in judging the trial process, not in judging the defendant.

Suppose the government charges you with murder, searches your house, and finds your sex toy collection. At trial they present some elaborate thesis about how you used a sex toy to kill someone, but do not convince the jury, so you're found not guilty. The public has a legitimate interest in judging that the trial was handled with integrity and that the correct verdict was reached. They do not have a legitimate interest in judging you based on whatever private information presented at trial might in some way embarrass you (eg, photos of your sex toy collection). On balance, it could be that the public-record interest does in fact justify making public the evidence of the sex toys, but you have to justify it on those terms. The transparency is not itself intended to be punitive.

Regardless of the effects, I don't think the case against MS was brought with the intent to "punish" MS through the trial process. The government brought the case because it thought it could win, it did win, and a judicial remedy was imposed. Trials are inherently unpleasant, but a just system tries to minimize this, not exploit it.

Any unjust policy (including just dispensing with trials altogether and allowing the executive to arbitrarily break up companies) will get to the 'desirable' outcome in some cases. That doesn't make it a just policy.

The specific allegation in the post is that the Trump administration will not appeal the verdict because Sundar gave $1M to Trump's inauguration. As far as I know, the government has not yet indicated whether it will appeal, so the claim that "Trump just paid him back, 40,000 times over" is in fact not true. (whether it becomes true at some point in the future, it was a falsehood at the time the author wrote it). It's also quite plausible that a Republican administration wouldn't appeal the verdict just due to being more pro-business in general, even without explicit corruption. But it's precisely because we have such a corrupt executive that it becomes all the more important to stick up for the rule of law. The correct response to authoritarianism is not to advocate for more authoritarianism!

Sure, there's a strong public interest in having proceedings on record. US civil cases are supposed to have a presumption of openness, which the judge weighs against other interests, like protecting trade secrets, confidential business information, privacy of third parties, etc.

The public record argument is fine; it's just a different argument than the extrajudicial punishment advocated by the original post.

If there's a general standard of transparency applied to all companies, fine. There are costs to increasing transparency, but certainly you could argue for that policy.

The argument that we should cheer on the use of government power to target a specific company, to selectively expose their dirty laundry as punishment for a crime they have not been convicted of, is what I found noxious in the original post.

> The government doesn't have to win an antitrust trial in order to create competition. As the saying goes, "the process is the punishment."

Regardless of what you think of Google or this case specifically, this is an argument for authoritarianism: that it is legitimate for the government to "punish" any company at will, based only on them falling into political disfavor.

> ... the only punishment Google would have to bear from this trial would come after the government won its case, when the judge decided on a punishment (the term of art is "remedy") for Google.

Yes, this is called the rule of law. Punishment comes through the courts, after a guilty verdict. The government has to actually win the argument as to what remedies would be proportionate under the law. In this case the judge didn't buy it. It's fine to disagree with his reasoning (or with the law), but the fantasizing about extrajudicial punishment here is frankly un-American.

You're totally right there must be supervision; it's just a matter of how the term is used.

"Supervised learning" for LLMs generally means the system sees a full response (eg from a human expert) as supervision.

Reinforcement learning is a much weaker signal: the system has the freedom to construct its own response / reasoning, and only gets feedback at the end whether it was correct. This is a much harder task, especially if you start with a weak model. RL training can potentially struggle in the dark for an exponentially long period before stumbling on any reward at all, which is why you'd often start with a supervised learning phase to at least get the model in the right neighborhood.
