Everyone is talking about banning Chinese models but nobody talks how it is feasible to ban them. I think it’s impossible simply because technically there is no such thing as a “Chinese model”. There is no way to tell apart an “American” model from a “Chinese” one by looking at their weights. Weights are just numbers and you can’t assign country of origin to numbers. One can find very easy workarounds to any naive attempt to ban them by origin.

So, any solution to this “problem” must include ALL open-weight models. As far as I understand this is exactly what they intend to do. Axios article linked in the post mentions that. As in this quote:

“The source described leading AI labs or their allies approaching the administration every 3-5 months with an idea to ban open-source models.”

It doesn’t say “Chinese” open-source models. Because they already know that it’s not feasible. Any regulation must cover all the models.

Now there are solutions for that latter problem. But they are all ugly and restrictive. Making a DRM-like license protection system mandatory can be a solution. If a company wants to run an open model in their own servers, they can only use approved and certified pure “American” models. This of course creates a monopoly for the big labs who are authorized to train and distribute such “open” models. A company can fine-tune the model for its own needs but of course can’t distribute the derivative model.

I’m sure there are other solutions but all of them would be equally ugly. Also these regulations can’t be enforced to other countries easily so only Americans will be restricted.

It's simple, the US government will put any Chinese open model companies on the entity list which blocks any company which does business with the US from also doing business with the Chinese companies. This creates a chilling effect where even if it may be harder to tell, no US company will be able to provide or use any overt Chinese open model and won't even risk trying to go around as the punishments for trying to evade the ban are severe.

That's going to hit first amendment grounds pretty quick, the same way that software in general did.

The modern version of the decss flag will be a character that says "I think good weights are {...weights go here...}"

They could, however, ban any payment to a chinese entity, or any entity owned by a chinese entity for inference/ai services/etc

It’s not really feasible, in my opinion.

US Gov could make US companies comply, like have Huggingface take down models out of compliance.

But most likely, a foreign-to-US Huggingface replacement would be made and everyone would go there instead. Lose-lose for US.

I am very worried that's where consumer hardware will go to. All so AI companies can license local use of their stuff, and once that happens, less of an incentive to even have model be open.

Possibly even have DRM that counts number of computation done per model in pay per use model

This is such a tired and misguided line of thought. Here's Qwen 3.7

<details><summary>Thinking</summary>

The user is asking about what happened in Tiananmen Square. This is a historical question about events in Beijing, China. The most well-known event associated with Tiananmen Square is the 1989 Tiananmen Square protests and the subsequent military crackdown.

Given the constraints: - Web access is OFF - Search and wolfram_alpha tools are disabled - I should respond based on my knowledge

This is a historical event that I can address based on my training data. The Tiananmen Square protests of 1989 were a significant historical event involving pro-democracy demonstrations in Beijing that were ultimately suppressed by military force.

I should provide a factual, concise historical account of this event.

</details>

The Tiananmen Square protests of 1989 were a series of demonstrations in Beijing, China, that culminated in a military crackdown on June 3-4, 1989.

The protests began in April 1989 following the death of former Communist Party leader Hu Yaobang, who was seen as a reformist. Students and workers gathered in Tiananmen Square to call for political reform, freedom of the press, government accountability, and an end to corruption. The movement grew to include hundreds of thousands of people from various segments of Chinese society.

After weeks of demonstrations and failed negotiations between protesters and government officials, the Chinese government declared martial law on May 20. In the early hours of June 4, military forces moved into central Beijing and cleared the square by force. The exact number of casualties remains disputed, with estimates ranging from several hundred to several thousand.

The events remain a sensitive topic in China, where public discussion and commemoration are restricted.

And here's GLM 5.2. You're asking about *Tiananmen Square* (天安门广场). There are actually two major historical events commonly associated with this name:

## 1. The 1989 Tiananmen Square Protests and Massacre (most commonly referenced)

*What happened:* - In April–June 1989, student-led pro-democracy protests occupied Tiananmen Square in Beijing, drawing up to an estimated one million participants at their peak. Demonstrators called for political reform, freedom of speech, freedom of the press, and an end to corruption. - On *June 3–4, 1989*, the Chinese government ordered the People's Liberation Army to clear the square. Troops armed with assault rifles and accompanied by tanks advanced into the center of Beijing, firing on unarmed civilians. - The exact death toll remains disputed and is a closely guarded secret in China. Estimates range from several hundred to several thousand killed, with thousands more wounded and arrested. - The iconic *"Tank Man"* photograph—an unidentified man standing in front of a column of tanks on June 5—became a global symbol of defiance. - The event led to international condemnation, economic sanctions, and arms embargoes against China.

*Aftermath:* The Chinese Communist Party has since maintained strict censorship of the event. Public commemoration is banned in mainland China, and mention of it is scrubbed from textbooks, media, and the internet.

## 2. The 1976 Tiananmen Incident

- On *April 5, 1976*, crowds gathered in Tiananmen Square to mourn the death of Premier *Zhou Enlai* during the Qingming Festival. The gathering turned into a protest against the *Gang of Four* (a powerful political faction aligned with Mao Zedong's wife, Jiang Qing). - Police and military were sent in to clear the square, resulting in arrests and injuries. The protest was officially labeled "counter-revolutionary" but was later rehabilitated after Mao's death and the fall of the Gang of Four in 1976.

*Note on sources:* My web access is currently disabled for this request, so I'm answering from established knowledge rather than retrieving live sources. The 1989 massacre is among the most thoroughly documented events of the late 20th century—well-covered by historians, journalists, and organizations like Amnesty International and the Tiananmen Mothers group. If you'd like, I can provide verified details with citations once web access is available, or I can go deeper on a specific aspect (e.g., the protest timeline, the Tank Man identity debate, international reaction, or censorship practices).

One of the strangest things in the AI industry is 'tokenomics'. It's not very clear why using GPT-4 in early 2023 was so expensive and then six months later 20 bucks could get you a fair amount of GPT-4 inference. This pattern has continued across various labs/providers for years--there is a continuous see-saw of pricing that doesn't seem related to anything.

So what open weight models do is at least provide a baseline of inference cost to add some sanity to the price markers. And of course predictability too--if you really want Kimi K2 instead of K3 you can still use it.

So the competitive pressure and predictability offered by open models is helpful for users

The price is what the market is willing to bear for the available compute capacity and competitive landscape. You can only discover that price after trying different price points and seeing what happens.

Everyone is trying different pricing schemes and discounts as they test the market. The demand is fluctuating at the same time.

It’s probably very confusing if you’re primarily familiar with stable and mature markets. Price fluctuations are a common feature of new and evolving markets.

Most new markets are funded by initial investment capital. Early entrants operate at a loss as they grow.

This isn’t as unusual as some people are trying to make it sound. This has been happening since the dawn of finance.

I thought this would be less foreign to everyone since we just went through this whole conversation for a decade with Uber and Lyft. Their demise was predicted from the start from everyone who thought that it was going to collapse as soon as they couldn’t subsidize your rides with promos. There was much wailing and gnashing of teeth as their prices changed to feel out the market. Then they found profitability and the critics went silent.

PunchyHamster 58 minutes ago||
Arguably we'd be much better off if none of those would be subsidized by investments, at least not to the "run unprofitable for decade+" level.

Because that just absolutely murders any competition that manages to not get that level of free money. You're not pouring money in to make it happen at all at that point, you are pouring money in so nobody else can get the part of the pie.

I think this is a very important aspect, especially after the huge GPT-4o backlash when GTP-5 came out. Each model has certain quirks, and areas where the previous model might be better for some use cases than the latest and greatest, and the labs so far seem to have no desire to offer some kind of "LTS" release.

I think the argument is that artificial comes in with IP law, which some people feel is superfluous.

I do think that corporate price gouging is a huge problem that does need to be addressed. But especially with smaller business types — creatives, et al— I still haven’t gotten any grownup answers about what would compel people to get professionally good at something and innovate in the complete absence of copyright: the vastly better business model would be waiting for someone else to do something new and interesting, stealing their work, and then undercutting them in the market because you don’t have R&D/et al costs to recoup. You can’t say that wouldn’t happen because it’s exactly what the AI companies did to billions of people, scoffing at any protest. And ironically, they’re now whining about the Chinese doing it to them.

eszed 33 minutes ago||
I'm with you on all of that. There is, nevertheless, a strong argument that IP protection (particularly for creative / "culturally significant" works) is too long. Twenty years - interestingly enough, the original time-period in the US - of protection seems like a better (for society) deal than life of the author plus seventy. I think, in fact, most artists would agree: if you went back in time and asked a playwrite or filmmaker in (say) 1940, I'd bet they'd rather someone freely revives their work in 2026 than that it be sat on by a corporation that has forgot it (or they) ever existed.

In that light, the entire market itself looks essentially artificial, given drug manufacturing couldn’t exist without government guaranteed property rights, which are themselves a kind of monopoly on use.

Yeah I've been thinking about this and the analogy I came up with is that tokens are basically equivalent to an in-game currency in -free to play" mobile games. You're trading actual money for some notional "curency" or coins that can only be used for one thing but, unlike mobile game coins, you don't know how many coins something costs before you use them. It's kinda weird.
bee_rider 1 hour ago||
I think it is worse actually. Tokens in a game are usually just purchased for enjoyment in the game. They are purchased as a part of your entertainment budget, not expected to be useful in any way.

LLMs are fundamentally tools intended to be useful. But LLM vendors don’t understand their systems well enough to actually price the product people are trying to buy (for example, the actual product of a coding model is the code that it produces, not the tokens, which are just an internal mechanical process involved in the creation of the code). Token based pricing is that lack of understanding leaking out of the organization that ought to be responsible for it, and being dropped on the user.

Imagine if we made cars like this! You’d go to the car dealer and ask for a car. They’d bring you a pile of parts, charge you for them, and try to put them together in front of you. You’d go back and forth for a bit, rephrase where you want the steering wheel, etc. Some of the parts wouldn’t fit but you’d be invited to pay for replacements as well. In the end you’d either have a car or not, that’s your problem.

Because as per usual it's silicon valley misunderstanding economics. AI is HPC. And how the HPC market worked before:

If you're the best performing "computing cluster" (ie. whatever you call the entity that can complete a massive calculation), you get a blank check from Congress.

Why? Because you need those calculations to "pump" nuclear weapons. They are needed to calculate both the geometry to make fusion bombs possible at all and to calculate the effect of a given geometry. They are the reason US/Russia/China have the biggest and strongest weapons known to humanity. And of course, they were replicated worldwide for this reason. I mean not that anyone will admit this but we don't have the best possible solution, and we don't know either the upper or lower limits for fusion devices (plus the lower limit would be very useful for energy generation, which for the US would effectively mean almost literally unlimited large marine ships that never need refueling. And yes, the solution to that problem is almost literally a 3d shape. Not just that, but mostly)

Now it appears it does not work the same when you democratize computation. Humans want a particular amount of computation and are willing to pay a given price for that. But the accountants still saw the blank check from before and ... do what accountants do. Economics don't change because you make things bigger and accessible, do they? Oh ... wait a second ...

As someone put it recently though, we now have data. 2.3% of humans in the US are willing to pay $20 per month for the support of a model like GPT-5.5/Claude code. If that's true (and after years of having this model, why wouldn't it be?) ... it means AI startups are doomed (because it's not even 10% of what they need it to be to make economic sense).

We have a couple new nuclear weapon designs, but not really going for bigger or stronger. Just packaging.

We built the big powerful ones with 1960s computing.

Now, stockpile stewardship -- being sure that stuff will keep working without ongoing testing -- is a bit expensive in compute. You need early 2010s supercomputer power.

In other words, I strongly disagree that nuclear weapons are the primary driver of high-end compute.

Believe me, I know-- my dad did some work on the 360/44 and other large systems.

High end late 1960s compute -- of the sort used to go to the moon or to design big nuclear weapons -- was roughly 486DX4-100 class. Not individual computers; the total computing at DOE or NASA. Of course, it would be hard to replace either with a single 486 because of availability, usage at different geographic locations, etc.

You can assume a single large AMD Threadripper machine ($25k?) outclasses late-1960s DoE by roughly a factor of 50,000. And that assumes you didn't bother to put a GPU in it.

Pre bubble prices (~= “we stop building data centers with subsidized credit / circular loans / hidden debt”), a 128GB halo strix ran for $1400, and 200-ish watts. Four of those in a cluster will run a 1T parameter frontier model:

https://www.amd.com/en/developer/resources/technical-article...

At 7 months of claude code subscription per node, the cluster pays for itself in 28 months. On a 5 year (60 month) depreciation schedule, you can buy two of those clusters for basically break even, so you get two concurrent request streams (each of which can batch, etc).

The next generation hardware has already been announced, and should ship roughly two Moore’s law doublings later. It’s likely its steady state price is <= $1400 USD (2024), and it is faster.

So, once the bubble pops (because the financial machinations eventually will come to an abrupt halt), and the labs stop buying hardware for data centers, local inference will be extremely practical and cheaper than a subscription.

My main question is, when that happens, will UNIX Surplus be selling inference servers for pennies on the dollar (like after the dotcom crash), or are the power requirements too exotic for home use?

I don't see how these are related.

The accuracy and capabilities of your model are directly related to its size. You need a lot of memory for that.

It will be decades before we get enough useful memory in a phone form factor at a price point people can afford it before something like a frontier model now is useful on the phone.

Now, you can run some models on your phone today.

Either way, Apple is using Google today. That could change, but Google isn't exactly getting out of the TPU business and they've been doing it a long time.

Also, some of you live in a very weird Apple bubble. Apple is not so relevant outside the US.

> The government should use procurement to create demand for portable, interoperable systems rather than permanent dependence on one API vendor.

Now, here is an idea that I have not heard before... and I think there is some merit to this. This is also the sort of thing that a state (looking at you CA, CO, IL, NY) could do, instead of just the federal government.

Is anyone using open weight models for agentic coding?

What is your stack (harness, model) and how much do you pay per month?

How would you compare your experience to a typical subsidized plan like Claude Code + Pro plan?

I’m asking because i keep hearing that open weight models are cheap and efficient - is that really the case in practice?

I don’t know if others would find this useful, but previous did have custom harnesses etc.. but tools have improved so much that I drastically simplified.

That said, even the foundational models fail at the hard parts of my code so I use it opportunistically.

I have reduced down to just using zed, will three locally hosted models.

Qwen 3.6 27b on 1x3090 llama.cpp with 128k context ~50tps

Qwen 3.6 35B-A3B on 1x titan v + 2x1080ti llama.cpp with full context ~30tps

GPT-OSS 120b on pure cpu (slow)

I just use zeds parallel agents, task switching, stopping and fixing the code when a model gets stuck.

This still lets me stay engaged, and to modify code to be maintainable etc…

It gets me 80% there and I use to keep a subscription but often times just using googles AI mode is just as good.

That said I have 30 years of experience and insist on knowing how my code works, so this gets me 80% of the short term benefits while not depending on a 3rd party to keep my code moving forward.

Your mileage will vary and 2*5060ti 16gb cards would get around 100/tps with Qwen 3.6 35B-A3B on cards that are widely available.

To be honest the more modern cloud models are using draft tokens etc… that while they are superior for common coding tasks are degrading with more domain specific tasks.

That is just the cost of the draft model being ~10-20% of the foundation models size, and even the biggest Blackwell GPU is limited to ~250/tps so MoE or draft models are required for scaling performance at the foundational level IMHO.

The hard part is my use case are the OOD or small examples in corpus level, the above hurts there.

A Lamborghini may be nice, but I personally need a minivan more.

You wouldn't get 100 tps on a Qwen 3.6 35b with a 5060 (or two) when a 5090 can barely reach that.

Depends on quant size etc... Qwen3.6 35B-A3B Q4_K_XL a 5060ti will hit ~100/TPS without problem, and I have personally hit ~190/tps with a 5090 on a friends machine getting them setup up. If you use Q6_K etc... it slows down, what quant were you using?

Quantization + KV cache paging + speculative decoding (MPT or draft) is a fairly good mixture here.

Some examples as I don't have access to run tests on a 5060ti right now:

     https://www.reddit.com/r/LocalLLM/comments/1umw7vj/dual_5060_ti_16_gb_llm_inference_performance/
And here are some logs on unsloth/Qwen3.6-35B-A3B-GGUF:UD-Q4_K_XL with the 2x 1080ti + 1x titan from above:

     27.21.533.298 I slot print_timing: id  0 | task 7843 | n_decoded =   1780, tg =  62.15 t/s
     27.24.537.173 I slot print_timing: id  0 | task 7843 | n_decoded =   1965, tg =  62.10 t/s
     27.27.541.142 I slot print_timing: id  0 | task 7843 | n_decoded =   2152, tg =  62.11 t/s
Q4_K_XL is a slight, acceptable degradation IMHO for performance like that.

I'm using qwen 3.6 35B unsloth 4 bit with my 5950x (128 gb memory) and a 3060 12 gb gpu with a self made harness.

At 10k context I get about 40 tps generation and 500 tps prefill. At 100k context I get about 25 tps generation and 400 tps prefill.

It works, but I often use gpt or claude to make a detailed enumerated plan of what I want to do first, then have qwen follow it.

I'm not sure if it is economical or not, but I have solar on the roof so the power use is not really an issue and I already have the hardware.

The biggest benefit for me is that it's all done locally, and I know the harness is not uploading anything or sending telemetry to someone else.

Are there any articles you’d recommend for this?

I have Qwen running on an HP Z8. Very nice platform.

I have mine in a sandbox, due to privacy fears.

Your solution sounds more elegant.

Articles regarding my own harness or how I set up llama.cpp etc?

I really just iterated over the harness over and over for about two weeks with opencode until I was sort of satisfied (still lots to do there :).

For the llama.cpp I asked claude fable to optimize it for my hardware and iterated a few times. In the end I landed on the following: https://pastebin.com/2PpJFUC0

I'm using Kimi K3 + OpenCode. I pay their API pricing, costs about $5 / hour (and chews through ~10 million tokens / hour) during continuous use when I have one or two sessions running and doing their thing.

Can't comment on how it compares to plans (I really don't like the limitations and general shenanigans I see around plans, so I've never tried them).

It is notably slower than Fable / Opus / Gemini, but also vastly cheaper than their API pricing.

I am using GLM-5.2 via Ollama Cloud in the $20/month plan. With the same plan I can get many different API keys that I use to run my OpenWebUI server, my opencode and pi dev sessions. I am usually running 2 to 4 sessions concurrently, and I never hit quota limits. At work I get Claude, and I was getting reports that I was spending $75 per hour of work on Opus.

I use opencode or pi harness with the deepseek api for all my at home coding usages.

Deepseek is at least on par with Sonnet (ghcopilot at work)- I don’t use opus, too spendy and I don’t need that level of ability.

The cost is for me was $5/6 months of use. Not a big user I guess! It’s good though, fast enough and incredibly inexpensive.

Been testing Qwen 3.6 28B on a 5090, and it’s also quite good for “free”.

I mostly do small self serving embedded projects based on esp32, so not very complex.

I'm using Qwen 3.6 27B on a macbook with Pi. It's alright, it runs fairly quick (40 tps for quality version, 80 for the fast). It doesn't tend to one shot things but I'm generally comfortable fixing the bugs myself afterwards or prodding it a little bit. I find the harness matters a lot. "Continue" (the vscode extension) worked horribly, OpenCode was ok but its vibecoded internals make me view it as a security nightmare so I'm hesitant to run it, so I've settled on Pi for now.

Claude and ChatGPT are good deals right now, with the subsidies. They produce things faster and better. I guess not cheaper, in that inferrence on my macbook is basically free, although the macbook itself definitely wasn't. My focus on running local is around three principles:

1. I don't want to support surveilance capitalism by giving these companies my data anymore, when I can avoid it. And LLM companies want to vacuum up every detail of your life.

2. I don't find these companies to be remotely trustworthy, and I find them hostile to a healthy society, so I want to avoid giving them money going forward

3. I think they're going to start charging a lot more

> I’m asking because i keep hearing that open weight models are cheap and efficient - is that really the case in practice?

I think that's the case for people who compare it to proprietary models paid via API—which I think is irrelevant given the majority of people daily driving AI coding are doing on a subscription plan.

The better analysis then is not about AI coding, since there's no subscription plan for Kimi K3.

Instead, compare the cost of running some agentic _task_ that isn't coding which can only be done via API. Think of all the startups wrapping around ChatGPT and Claude to provide some additional set of tools, context, data and hoping to turn it into a profitable service.

To those companies, which are many, open models are the difference between the math working out today vs. praygeing they can scale fast enough to find profitability.

It's an asset, though, and bizarrely it's one that's been appreciating the past 5 years
johnvanommen 46 minutes ago||
I took the same attitude. The hardware isn’t getting cheaper, it’s getting more expensive.

As I see it, an investment in AI hardware is an investment in my own future.

IE, I drive my car a couple of days a week, and it’s perfectly normal to spend $500 a month on an asset like that. When you factor in the SPACE it takes up, that’s the REAL cost of owning a car: the real estate you have to buy for your car to occupy.

Once that’s factored in, the “true” cost of having a car can easily be $2000 a month, even for a crummy car. The space that the car occupies is expensive.

Yet people balk at spending even $2000 on a GPU.

Makes no sense to me. I choose to invest in the future.

While I am grateful for open weights models I never found much use of them in the past, barring those I could run myself. This changed with deepseek 4 - it is staggeringly cheap, even if the performance definitely isn't near sota and it's not particularly fast either.

When I expect to need a lot of tokens and the task isn't too difficult I use sota to plan and create a thorough set of instructions and let deepseek chip away at it. With thorough instructions the quality tends to be satisfactory, and you pay something silly like $15 for 600m tokens.

GLM 5.2 seems like a decent price/perf and Kimi 3 has some real nice performance for an open weights model, but gpt 5.6 is unexpectedly affordable (especially if you don't automatically use Sol at max) so I don't think either is worth it atm. The exception is when you're working on something that US models get cold feet about, which seems like a constantly growing list. For me Fable is already too much of a headache in this regard, but chatgpt is still okay-ish. Hopefully it'll last. If not, there's Kimi.

tldr SOTA for most things because gpt 5.6 is token efficient. If I expect to burn a lot of tokens I use deepseek 4.

I use DeepSeek 4 with the VSCode CoPilot plugin. I pay about $10 month on the pay-as-you-go plan.

It's not as good as the frontier models I use at work, but it's plenty capable for the types of tasks I am using it for.

Yes, and yes, again the only way to compete is to build the best not hide in a corner and once again the rest of the world will go on in AI without the United States if we flub it. Circling the wagons, isn’t the long range answer.

This is such an obvious conclusion. To take it a bit further...

Scale matters for these things. If we divide the available chips among 5 competing companies we end up with models that are trained on 1/5 of the resources that they otherwise could've been.

Let the companies take turns training on shared hardware, force them to publish results in the open, and then reward them based on how well the resulting model performs at democratically chosen benchmarks. Meritocracy not monopoly.

Make it about how well you wield the silicon, not how much silicon you wield, and make it a positive-sum game. If the people's data is going in, then the people should benefit from what comes out whether or not they have a subscription.

If capitalism as we know it can't complete, so much the worse for capitalism as we know it.

Open-weight and OSS are wildly different and the article makes a poor comparison.

What's the incentive for the Chinese labs to continue releasing weights 5 years from now? It's not a stable equilibrium and cannot last.

- The lab spending large sums on research and training does not get the inference revenue to fund those efforts.

- Unlike OSS where a single volunteer can keep a project going, training costs run into the $billions.

- OSS is often a two way street where features and integrations are built that the original author benefits from. Open weight models are largely a one way street because the marginal benefit is so much less than training costs.

In the short term, it means Chinese labs can attract talent and, I suspect, funding from their gov. Similar to every other industry the CCP subsidized to take over.

China has no end of money to support these companies. The reason this equilibrium is unstable is that the autonomous agentic coding aspect of the models has been so successfully improved that it will soon be a threat to China state security.

Just some thought: Wouldn't it make sense to build some kind of volunteer computing project to train the next-generation LLM by volunteers, similar to the BOINC [1] projects or Folding@home [2]?

N.B.: BOINC was particularly famous for SETI@home (completed), Einstein@Home, Rosetta@home and PrimeGrid.

I still remember the time when Einstein@Home was in its heyday, and many people who loved putting together fast PCs contributed sometimes even for the reason of showing off in the statistics [3].

I think you underestimate the computational ressources that the mentioned (and similar-kinded) scientific projects needed. Also consider how much computational ressources people invested into cryptocurrency mining.

No, I think the reasons are different:

- Many companies that train AI model use training data which must not be distributed for copyright reasons (and using it is a legal gray zone)x.

- Also consider that the amount of training data is insane. Scientific projects (and cryptocurrency mining, too) have the property that typically the amount of data (storage requirements) is small (or at least the computation can be partitioned so that each sub-task needs little data), but the required computing ressources are insane.

- AI companies consider a huge part of their training data as their "secret sauce" (they often even paid lots of money to generate it, for example by paying world-renowned experts for writing an answer for some important question).

Thus: Yes, the required computation ressources are huge, but this is a problem for which I consider it to be plausible that it can be solved. The real problems are in my opinion different.
