So the closed model try to get client with their model by saying it's cheaper than employees, and then turn around to lawyer-out cheaper alternative?
Truly the american dream.
Even in the US, only about 23% of workers earn $100k/year or more.
According to the US BLS, the median income for "knowledge workers" is ~$65k-$72k/year.
People in SF, NYC, etc. live completely different lives from the rest of the country.
Why Kimi? because K3 is the only frontier model I can have a serious conversation with about my product's security.
(I did apply for OpenAi's Cyber Pilot but got no response)
(Grade 3 AI which can hack both previous tiers is exclusively sold to the highest bidder.)
It's also not a very good marketing strategy, secure software and quality also goes in pair and it just makes me doubt about the output of Fable/Sol

No wonder openai and anthropic are terrified
Models are quickly becoming a dumb pipe, like an ISP. Just a commodity. The labs should rightfully be terrified, eventually the value isn't going to come from the model itself but the tools & integrations built on top. Non-tech businesses and non-tech employees don't want to buy API access to a model, they want to buy off the shelf software with its capabilities packaged up into a pretty, easy to use GUI.
Claude Team w/ Cowork still only lets you set R/W permissions globally for each MCP connector for the whole team, they still don't offer config on a per-user basis. The enterprise controls are sorely lacking first party. Maybe fine for most startups or flat orgs, but any established enterprise with strong identity & access governance is going to have an issue with that. You can make it work, but you need to make your own agent/harness and give it an identity in Entra or whatever else you use, so for a non-tech company without a dev team, right back to square one of preferring to just buy a COTS solution vs trying to hand out direct model access with minimal governance.
(M365) Copilot sucks but Microsoft is putting a ton of work into agent governance & identity that sorely lacking elsewhere.
The oddly reminds me of back in the day when SOPA had caused a similar stir (https://en.wikipedia.org/wiki/Stop_Online_Piracy_Act), and all HN was up in arms against it.
Predictable power play by corporate strategy and legal departments.
Microsoft and Meta are also-rans at this point. Their best hope of catching up is probably leveraging their infra and open models.
And as a more general point - more major competitors in a domain is very good for everybody except those competitors themselves, who would rather there be as few as possible.
So Nvidia benefits from more inference providers running many Chinese models that they otherwise would not have been able to service.
If I were cynical, I'd say it isn't helped by the current US administration.
The other thing that comes to mind is they want to avoid the government from banning open models as has been suggested by some of the closed models providers.
If we go down the line of dead internet theory which I’m becoming more convinced of these days, the volume of information that’s not necessarily original or extracted from reality and just interpolated and extrapolated from existing information in different ways by LLMs will greatly outnumber human information coming up.
In which case these models should.. start to converge on the same data I imagine, with slightly different behaviors within that. One big generative orgy feedback loop.
Could you elaborate? I don't understand your implication.
Amazon in particular hosts open weight models via Amazon Bedrock (e.g. Ministral 14B 3.0, DeepSeek V3.2, ...)[1].
In case it changes the context of this comment, I am a Meta employee, all opinions are my own.
[1] https://docs.aws.amazon.com/bedrock/latest/userguide/model-c...
This is the correct stance, hopefully this is the stance that prevails.
The Chinese open models are way ahead, not by how capable they are compared to frontier models, but on how they project to the world and how they improve over time.
The gap is shrinking, but considering their models still lag our frontier, I wouldn't say they "run circles" around us.
It makes sense to see Meta, the startups, and the VC firms on this list. And it makes sense to see OpenAI, Anthropic, and Google all missing. Microsoft is somewhat unexpected to me. I don't think of them as having a focus on open weight models (no more than Google), and they have a large stake in OpenAI. Maybe they're looking at this from the angle of Azure providing compute. But then why is Amazon missing, when it has AWS?
And of course, we don't see DeepSeek, Moonshot, or Z.ai on here. The letter is about American technological leadership after all. But then we _do_ see the French company Mistral! Mistral who released [a playbook](https://europe.mistral.ai/) for Europe becoming a self-reliant AI powerhouse.
I assume all of this is in the context of influencing the Trump administration's thinking on Chinese open weights models. But the letter is really about _American_ open weights models. The call to action is all about keeping the American open weights ecosystem competitive. I didn't even realize that was under threat, so I feel like I'm missing something.
Therefore it is no surprise that both companies are among the signatories.
The motivation of Palantir is very transparent, they have launched a product created in cooperation with NVIDIA, which is a turnkey system (Sovereign AI) that includes all hardware (i.e. a rack with servers full of NVIDIA GPUs) and all software needed by a company to run on its premises LLM inference and also training/fine tuning.
Thus the Palantir product competes with OpenAI and Anthropic and it benefits from the existence of open weights LLMs.
The motivation of Microsoft is more obscure for now, but because its criticism was very similar to that of Palantir, about how dangerous it is for corporations to delegate the processing of their AI needs to external entities like OpenAI and Anthropic, I assume that Microsoft is also going to propose an alternative to using remotely the OpenAI and Anthropic APIs.
Unlike Palantir, Microsoft is not likely to suggest self-hosting on premises, but I suppose that they might promote self-hosting on some kind of instances rented from Azure.
AI models don’t really have nationality. They don’t have race/ethnicity fields on their model cards. It’s impossible to determine the country of origin of a model by looking at their weights. There is no DNA test for AIs. They exist in a mathematical space where human-made borders make no sense.
This means IF there is a regulation for open weight models, it has to apply to ALL open weight models. There is no any other option, since you can always train/fine-tune a model to change it’s weights and rebrand it as a new model.
How much of that is organic versus something a agitprop agent is commenting in places like HN would be interesting to know, but people very much talk about that from a nationality perspective.
MS is playing literally all the sides in this whole AI thing. They are a massive investor in oAI, and have lots of rights to use their models for a long time. They also have the cloud where they offer inference w/ all the benefits of already being there, data retention, etc. They also have a research wing that can build models (rumours are they're aiming for frontier-ish). I don't think there's currently an angle in this AI thing that MS hasn't aimed for.
(a) sellers of hardware (Nvidia, IBM) and those who rent hardware out to others (Amazon, Microsoft)
They want open models because they don't have to license it to run it on their hardware, so they can offer lower cost and inspect what they are offering to clients
(b) open model creators (Arcee, Perplexity, Mistral, IBM, Microsoft)
...who would be unable to work if open-weight models are banned
(c) Software-heavy companies ( Mozilla, The Linux Foundation , ServiceNow, Microsoft, IBM, heck all of them)
...who want models that are cheap to run because that reduces the cost of running an LLM (whether you are trying to replace a software developer or just assist them, the value of a reduced cost LLM is directionally the same)
OpenAI and Anthropic can bring American open-weight model providers like Meta to court but not the Chinese. Chinese companies breaking American IP law (whether the law is correct or not) are basically immune. This has been going on forever, I guess enough is at stake finally for the federal government to care.

remember when bitcoin got its first dedicated hardware, will be like that
If I change one weight in Kimi, is it still a Chinese model?
If I fine-tune Kimi on pro-America nationalistic freedom loving anti-Chinese propaganda, is it still a Chinese model?
If I distill Kimi from one server to the next without ever directly transferring any weights, is it still a Chinese model?
If Claude accidentally trains on some of Kimi's output, is Claude then considered to be a Chinese model?
If China's next open-weight model is released secretly through a European company, is it still a Chinese model?
Ungovernable makes intuitive sense, but I don’t understand how open weight models could be decelerationist or slow the development of the frontier. Was there an argument for those positions?
In other words, if AI models become a commodity, the "AI leaders" will not be able to burn the cash like they do today, thus resulting in a "slower" (one could say instead "more sustainable") development of AI models.
I don't know that the US government has a unified position on open source AI. But it's not like this isn't a discussion happening among policymakers.
Is the US planning to invade China and take away their models? Because otherwise China is still going to have the models even if the US bans them. I don't think they're going to be going with the US position on this one.
Then will attempting to cutoff China again today work or do we expect that also will prove to achieve the exact opposite of what its proponents are claiming?
The Chinese government didn't like that idea. They attacked American companies, stole the IP, and created their own analogs of American corporate offerings. If you are a company and are targeted by a totalitarian government, it's not unreasonable to pull out of that totalitarian government's jurisdiction.
Honestly, the American response to that was not nearly stout enough. Chinese goods and services had been sold in the US without issue for decades at that point, often to the detriment of both domestic and other international market players. When China was expected to play by those rules and allow American companies to do business in a mostly-unfettered way, they attacked the companies and drove them out of their market.
Start with the outcome you believe will be the most in line with the spirit and traditions of the open source community. This is precisely what won't happen.
It won't necessarily be the inverse. It could be, of course, but it's also likely to be a compromise between the two.
For a topical example: The companies doing "AI" layoffs aren't doing so out of a sense of having failed their staff that helped carry them so far. Often, these announcements come on the heels of record-breaking profits. They're doing it out of contempt for workers.
See https://www.cnet.com/tech/services-and-software/cory-doctoro... for Doctorow's take on centaurs vs. reverse centaurs. Broadly speaking: C-suite business leadership wants reverse centaurs. Workers want centaurs. Unless you have a union (or some other collective bargaining power structure that I'm not aware of), the C-suite calls the shots.
The same can be said of the current administration. They don't give a fuck what most of us want on any given issue. They're captured by an aggressive ideology. Their only incentive is to be able to spin their decision to make themselves look good; to posture as "strong" leadership.
there's nothing open source about an open weight model. It's more like the binary blobs Linux fought so hard against. If you can't compile, or in this case train, from source then you're missing the "source" part of open source.
While your point is valid on its own merits, it isn't relevant here.
Hey nvidia, what about making your full set of linux drivers open source?
I mean, I do agree that being open is important but you're hijacking the narrative here, and I suspect being open have nothing to do with any of this.
And besides, it seems to me like the ethical choice. Given how these models are, in some very real sense, mechanical plagiators, built on the generosity of creators past and present, some of them now in danger of being replaced by the machine. I think the least the labs can do is open these models up. These and other such considerations were the reason OpenAI started with that name. Of course, it was questionable that those ideals would survive the encounter with generational wealth. Just look up what the founders of Google were saying about advertising when they were two students tinkering at an as of yet unproven tech. Same thing for OpenAI, self-interest speaks that much louder when there's real money on the table.
It just boggles the mind that people now make excuses for their all-too-predictable about-turn.
Perhaps worth not calling them "labs". Are they not (for-profit) companies?
There's nothing "open" about China. Google, meta, openai, etc all blocked. Go visit and see how it goes when you try to access your gmail or open facebook. Try to use chatgpt. Try to get citizenship and see how that goes. China blocks many western companies with their great firewall and force internal similar products. This is smart, China wants to prioritize their own.
To me, "open these models up. " must mean provide all the data and supporting documentation required to reproduce the model. That would be "open". Postgres is open because you can download all the data and supporting documentation and reproduce the binary yourself. However, being able to only download a postgres binary would make it no longer open.
Additional training on top of an open-weight model sounds analogous to writing mods for minecraft. You may change some behavior but that doesn't make minecraft "open".
Having a standardized training set is valuable, though.
Like, that's just a logical thing to call it. I don't believe anyone is making a judgement on the intelligence of the reader to call it "open weight" when it refers to weights that are openly available.
"Open source" would be a more appropriate term to describe a model which also includes the training source.
Instead a bunch of tech companies are gathering to try to stop OpenAI and Anthropic fear-bouncing the White House and the Republican Congress into giving them regulatory capture and repeating the mistakes they are making around RISC-V.
Those mistakes won't just entrench two companies, they will entrench the bigger-better-faster-more model (closed companies making ever bigger cloud-bound models) when it is abundantly clear that enormous progress can still be made on smaller, even desktop-bound models (where, due to distribution, open weights are essentially inevitable).
Regulatory capture that stops open weights work will also have impacts on local and on-device AI work, as well as on academic research.
Note: Just pointing out the comment intent and nothing else
nVidia did and they released good models – same with Meta, Microsoft, IBM, Mistral – all are signatories.
It would seem as if the community either isn't doing that or is relying on the Chinese to do that.
> Distillation ... reflects a long tradition of learning from, building upon, and improving existing technologies, a tradition that has helped drive innovation since the rise of the open-source software movement. By contrast, unlawful efforts to extract value from closed models raise legitimate concerns. Those concerns should be addressed through targeted legal and commercial frameworks rather than sweeping restrictions on techniques that play an important role in AI innovation.
Sounds like they are saying "please protect our IP theft" that created closed weight frontier models in case we arbitrarily decide to close our models. But don't get rid of distillations in general so that we can all also keep benefiting from open models. We don't want to lose the ability to benefit from the work of others as we launder IP into closed models.
Surprised Linux Foundation kept their name on it with that.
i've said this in other comments but the fact that these companies are trying to align with open-source when there's no "source" included with their models is pretty damning. I think it lays bare the absence of any kind of noble or righteous motive with respect to distillation.
Microsoft, NVIDIA, Meta, Palantir, IBM...They have all been actively hostile to open source for decades, and have a history of embracing it only when convenient and profitable.
Microsoft benefited from its close partnership with OpenAI for years right up until it went sour. Where was this enthusiasm for open weights then?
Meta was developing open models and then abandoned that effort in search for profits. Muse Spark is now fully closed.
All these companies have the resouces to train and release frontier open weights models today, but choose not to. So spare me the marketing and virtue signaling.
