Speculation: open models is what will kill Anthropic and OpenAI. Hyperscalers can run the models without a licensing fee. Apple can make them smaller and put them on the device.
The frontier models are an edge and a liability. They're astronomically expensive to train. Without them, their models will fade into obscurity. Their marketing depends on people believing the models are meaningfully different, as people have sweatily argued on this forum. Personally, I'm not convinced there's much of a difference between these models at this point. The harness is what takes these random and hallucinogenic models and make them into something deterministic and useful.

The outcome is plausible. Open weights models though look like a tactical more than a principled play by Chinese companies to overcome the disadvantage and difficulties to access western markets. Two issues:
1. If market conditions change they might decide to close down like Meta did.
2. If as you said models keep getting more expensive to train, is an open weights strategy financially sustainable?

That's probably pretty likely, but if we're honest, are LLMs built and funded by a hostile Chinese authoritarian regime any more dangerous or harmful than LLMs built and funded by a hostile American authoritarian regime?
China absolutely does not have my best interests at heart, but America's technofascism is probably more immediately dangerous and harmful. Americans genuinely have more to fear from America than China at this point.

Open models are probably also comparatively astronomically expensive to train - just less so than the frontier models because they’re somewhat smaller, +/- the creators are more incentivised to focus on getting more from less compute because they’re have to, +/- they rely on distillation of the frontier models and this is more efficient.
But efficiencies aside; creation of open models still requires a lot of money and compute from a large organisation which is willing to accept zero return for that spend. This largesse is unlikely to continue forever; so the question is which will crack first, the frontier models’ business model or the fast followers’ generosity?

Yes, the problem with comparing open models to open source is that open source requires humans to volunteer their time. Open models requires humans to volunteer their money.
These two types of contributions have very different behavioral profiles, and it doesn't obviously follow that the historical success of getting people to collaborate socially on building software for fun and for the benefit of the community will translate in any meaningful way to the necessity of being able to raise enormous amounts of money to pay for enormous amounts of electricity.

I don't think it needs to be framed purely as generosity. You just need a sufficiently self-interested actor that sees open ecosystems as a necessary part of reducing their own risk profile, relative to the alternative of complete reliance of a third-party business that can take an exorbitant cut and/or Sherlock them at any time.
Valve and SteamOS are a good example of what this idea looks like in practice. (Though they may also illustrate a third thing you need: a privately-run company, that has enough profit, and enough commitment from leadership to the company's vision, that they can make long-term bets without having to eventually bow to investors seeking short-term gains.)

I’m not exactly sure on the “how” but it only makes logical sense for (non-AI) companies to band together to fund the training of a shared model. Apple is a great example, AI is not their core business but they still require it.
The only thing that took us down a different path is the vast sums of VC funding pumped into the AI companies.

How does it work if people flock to open models but they're too expensive to train? What is the financial incentive to do so?
I seem to understand open models are mostly coming from China, and the benefit of training and releasing them for 'free' is a powerful geopolitical weapon against the Western/US economy that at this point depends on OpenAI & co. to succeed.
Will the West make open models illegal?

I would definitely pay a monthly subscription to help fund a non profit compete with Anthropic and OpenAI. I already pay subscriptions for myself and 2+ other people. It's a non brainer to be able to pay for the training of better models that I can then run myself for many more. I hope someone starts this, I think this model would work. I'd start it today if I had the team and initial capital to bootstrap the infr. I know VCs won't fund it, but we definitely will, enthusiastically and continually.

I'm a bit skeptical of the token cost/ROI for all models, but sunk costs are sunk.
It has the feel of self-improving super-intelligence or bust to me. If you get that, the frontier model(s) run away with a faster exponential. It's a bit like semi with Moore's Law with silicon, GaAs could never catch up. If you don't get it, the fast followers crush the high investment and there's no moat. Not like they can enforce copyright!

My prediction is that hardware costs will make open source models impractical for the foreseeable future.
Yes, tinkerers and enthusiasts will continue to make use of them, but frontier companies will maintain near total dominance because they will be the only ones with access to the hardware.

For the near future it seems that the new models will consume whatever improved hardware capacity we have. Competing with that is challenging, but I also think there will be strong economic incentives towards cheaper but adequate models on other providers.
I don't think we'll see home users being able to match even the low end clouds for a long time.
Longer term I think we'll see these uses of AI cluster into a few groups:
- maximal code / reasoning quality, at high prices (Fable)
- typical code / agents (sub-Opus, Terra)
- cheap but decent enough quality (think Deepseek / GLM / Luna)
- so cheap I don't care about utilization (Deepseek, and friends)
And also more niche ones:
- ultra fast with high quality answers (typically sub-SOTA). Cerebras / dedicated silicon type approaches, expensive.
- ultra fast with mostly-adequate answers, and an openness to retries, moving up to better models
I think the open models will dominate (not with individuals, but low cost providers) all except the top 1-2 of those categories, and there will be a continuous erosion on the big player's moats. The top categories are also where all the money is, but I'm not sure it can justify those investments long-term. I also think they will have to squeeze more money out of them to justify the investments, which will also drive people down the list.
Edit: clarifications.

Completely agree. Once I can reliably get open models doing what I am on Fable ultra I imagine I will switch for good. I am fortunate to have access to a decent bit of local RAM, 192GB of DDR5 at an OK speed. It is not enough and costs are well past absurd. In a few years time I envisage a setup that is sub $10k which can accomplish such tasks. The pace so far has been breakneck. That is all I personally need. That may change, but until true AGI I do think there will be a ceiling to how much I will pay for something frontier if it is only marginally better.
wosk 3 hours ago
This is easier to say as Fable is good (even SOTA). But people have been were saying this continuously for the current model and for now the improvement are still coming.
A better question is would you settle for o3 now or pay 20$ or 200$/month for fable ? Because o3 quality is available OSS.
It is like the new IPhone, in some sort. At some point come a feature many would like to have, despite diminishing returns.
We will see how long labs can keep up and what the scaling curve look like, but I would be more worried into losing sota status to Chinese companies than letting them take the open non-sota approach.

I agree with your speculation to be honest. And yet I’ve tried several local open weights model now and none gives the same quality of answers as Claude gives me on a regular Sonnet model. Mind you: I am “running” 48GB of RAM so I can’t try every model. Where does this difference come from? Can we actually get close locally?
midnightbobarun a minute ago
Something I've noticed is that local models are giving better answers these days than they did a year or two ago, even if the size (in parameters and in the amount of RAM used) hasn't increased. I'm not familiar enough with the technical side of model training to explain how they're doing this, but I think in another couple of years, models that use up 48 GB will be able to squeeze out even more incredible performance.
Though on the level of something like Sonnet 5... well, maybe not.
pocketarc 26 minutes ago
You’re running 48GB now but imagine a future where everyone has 512GB RAM or 1TB RAM in their computers (it might sound like a lot but also 20 years ago we had 512MB PCs).
It’s not hard to imagine what 5-10 years of pressure to increase RAM will do to specs, on top of the normal tech improvements.
That’s worth bearing in mind when thinking about local models.
Plus, local models keep getting better and better; 2 years ago what you could get out of those 48GB of RAM was embarrassing compared to what’s doable today.
We’re getting there. Just takes time.

Speculation: Anthropic and and OpenAI become more like hedge funds, keeping their models to themselves, using their them and their compute for market/event prediction, internal tech development, and AI self improvement. I already wonder if that is what Google is doing. Why release your best models to help the competition? Their published models are good enough for 99% of consumers, and they can leverage their market dominance in other areas to put that consumer model in front of eyes. Then the decision to improve your internal models would both depend on whether you think they'd have value internally.
Yeah, I'm pretty sure AI is going to go insular within the largest companies. This will only be hastened by the growing national security concerns/awareness.

If consumers ever have enough VRAM for it locally, sure, otherwise nowhere near close.
Nvidia is looking like they are ditching consumer markets in favor of enterprise GPUs since nobodys heard a peep about the next iteration of RTX cards. The 60xx series is postponed till 2028.
Nvidias playing a dangerous gamble, in my eyes I see all the frontier labs eventually just only buying Nvidia chips for training and building custom ASICs for a fraction of the cost, longer lifespan and cheaper to host.
This will eat their 5 year gravy train for GPUs vs the 10 to 15 for ASICs.

The real moat aren't the models, but the tooling around the models that allow them to perform specific tasks/goals. That's what really sets apart frontier vs open. Open only has the model itself, closed have the tooling to enhance the model.

As these frontier companies have been boasting, writing software is now a negligible cost because the LLM can do it.
IOW, no, their software can't be a moat, because, according to their own arguments, you can use their LLM to trivially clone their software.

unfortunately, for me, that's an anti-moat; their dark, inconcievable, alignment, random "no goblins" and inability to be reliable where their models are inevitable non-determinant means you're going to constantly run into the "this worked yesterday" problems, no matter how smart the models actually are; being filtered constantly through economics, political and ego-maniacal filters means everything you do with it will break at any given interval.

i doubt it. it cost money to train a model. we can see that with the price increase for Kimi3. Chinese AI companies is leaving a lot of money on the table for third party providers. you think they going to let go of those money that they can make. sooner or later they will want to collect. after all, none of Chinese open weight model is release by a none profit. its all for-profit companies that is releasing open weight model.

I can't take anybody seriously when they keep declaring open models is beating frontier models. What they don't understand is that besides the huge capex to train and run inference, the real gold is in the human response to the prompt results, this is what all the Chinese companies are making their open models dirt cheap and distilling american frontier models via scraping.
The idea that we can out-parameterize frontier models is a common misconception, the true moat that Anthropic and OpenAI is why Chinese model providers are open sourcing and making it dirt cheap to keep pace through its "proxy chain operators"

You can run the same harness on fable, opus, sonnet, and see a huge difference between them. It is true the harness is important, and openai has begun encryption its instructions to swarmed sub-agents instead of just encrypting the chain of thought, but the model is still important at this stage.

You're saying it's important to have up-to-date facts stored in parametric knowledge? It seems to me like that's grown less and less important as agentic capabilities have grown. Even if a frontier model doesn't know something, if it's out there, it can easily find it through tool use.

The thing about not much difference between models and the harness making them deterministic and useful is wrong. Also models have different strengths and weaknesses and some are better at almost everything by a large margin compared to others.
As for your speculation, I think it's hinging on some companies releasing models for free or no big differences between models. In a world with hyperscalers and companies training models you can quickly recreate Anthropic or OpenAI by having an hyperscaler ally with a model training company, train a good/a better model, and not release it.

Open models are 4k TV (or maybe 1080p tv now and 4k TV soon) and SOTA frontier models are 8k TV. Can I or the average user tell the difference? Not really. Would they pay for that difference? Not a chance. Our entire economy is teetering on some future hope that this fragile and immaterial difference will pay off, when the reality is that LLMs are a race to the bottom and eventual razor thin margins. Maybe a tiny vocal subset of programmers can use it for work and make paying for it worth it to them, but that can't prop up an entire economy, especially when said programmers are phased out, jobless, and replaced by AI with each better iteration...

>There were a million cell phones before the iPhone took over the world.
You have tripped yourself up there.
iPhone took over as it introduced something innovative over standard phones, but then Open Source (Android) matched the multi-touch and software differences and Apple's branding, lock-in and design etc have managed to keep it as a big player in wealthier countries. IPhone also came on the back of the massive iPod success.
ChatGPT launched the same innovation vs Google Search, but just like Android Opensource AI is moving fast now.
Android has 72.7% market share at present, Open Source AI will do the same unless the frontier labs can continue to do something new.
The frontier labs are saddled with enormous investor and other debts. How long they can keep innovating by spending so much on R&D and paying there staff very high wages remains to be seen.
Once investors cash out via an IPO, the companies are back down to earth and playing in the real world again.

Exactly 4 months ago, the marketshare on openrouter was 60%-40% in favor of closed models. Now it's 63%-37% in favor of open models. On March 19th, the open models processed 888B tokens in aggregate, yesterday, they processed 4.19T tokens in aggregate. That's almost 5x in 4 months!

I think the frontier AI companies think you're missing key details:
- they can still discover entire new untapped markets for AI (that, potentially, only their models can unlock)
- they can find (novel, unique to them) ways to drive down the cost of running their models
- they can provide other ancillary value (e.g. write better harnesses) because of their expertise, and then charge for that value
I'm probably missing a few bullet points also. However, none of those are moats (or at least not yet) ... I'd consider them more like bets. The frontier AI companies are betting "the house" on them, and if they pay off they could, hypothetically, make them financially competitive.

Mozilla presents themselves as an "open community". But they are a commercial corporation bankrolled by Google, and with an oppressive organizational culture. I would interpret this post as being not just about an opportunity for their self-aggrandizement, but also Mozilla trying to whitewash its mass surveillance of users, likely used also to train some model or another, or perhaps just to feed their patronn (Alphabet)'s ad machine.
They tell us about how the farmers and native people and whateve are all happy with their chatbots and models. The major effects are a massive and ever-increasing energy use - in a time where we must cut back and economize to avoid further global warming; a massive diversion of investment capital - especially in the US; fantastic stock valuations for a few tech giants (gee, I wonder whether any of them is related to Mozilla somehow); and other effects one could survey, all more significant by far than the examples they bring.

I think it’s supposed to mean “open source is easily shipped, but open source is hard to deploy”? Or perhaps “deploys hard” is a figure of speach, as in “we are deploying this open source and we are deploying it /hard/“? I don’t know, it’s not good.

This is truly some proper slop. The "PRODUCTION RATE BY COMPANY SIZE" graph has bars that start offset from the text underneath them, which LOOKS like a mistake that happened due to word wrap, but if you visibly compare the 54% to the 55% bars they seem to have compensated for this?! I can't tell if his was on purpose or accident and it's impossible to take the data seriously!
This is on mobile in portrait. In landscape the text doesn't wrap or offset anything.

It's their own fonts: Mozilla Headline and Mozilla Text.
No idea why they'd be using the display font for the abstract though, that kind of defeats the whole purpose. It's supposed to be quirky and bold, but used far more sparsingly.

mozilla only began babbling about open source ai when they got their teeth extracted for free via the entire community giving them the curbiest of curbstomps.
i still use firefox but hot damn did they utterly fail to read the room initially. the only other company i can think of in recent memory -- besides sony cutting out discs -- is logitech when their ceo began gibbering about a subscription mouse or microsoft and its copilot button(s).

It's frustrating because I truly believe they are well-meaning, honest actors. Every single "controversy" surrounding Mozilla can be directly attributed to miscommunication rather than malice. They do often struggle to read the room.
That said, the takeaways from this report are exciting, and I do feel that Mozilla now has the right lens in their assessment of OSS AI and their own approach to ensuring interoperability and setting open, modern standards.

This new trend of content appearing while scrolling down is so terrible accessibility-wise, I do not understand how Mozilla of all institutions would do it.
Not every trend needs to be followed. Have some backbone. You receive donations to have that.

Apart from the website being - frankly - bullshit, the content is also - frankly - bullshit.

Could you explain what is wrong with the accessibility of this page? All the content is included in the html payload, so it is accessible to screen readers and text-based browsers; and as for the "reveal" effect, it seems to respect user's choice of "prefers reduced motion" and is disabled when that is user's preference.

> it seems to respect user's choice of "prefers reduced motion".
Cool, that I didn't check, because it is impossible to enable that setting, as it breaks _huge_ amounts of websites.
I'm not aware of a way to enable it selectively, but one could also just display the content at all times. It's a static page. It's static content. None of this makes any sense.

The idea behind that style of gradual reveal is probably some kind of storytelling, but the only story it tells is that mozilla is wasting donations on people with incorrect opinions that could be used on.. idk not building torment nexii?

Quick fix for the font, which many people are (rightly) complaining about.
Array.from(document.getElementsByClassName("quote")).forEach(p => { p.style.marginTop = "20px"; p.classList.remove("quote", "reveal") })
The issue is that all of the text is a quote, and that renders enormous. That’s probably fine for a tiny quote amongst more text, but here it is jarring.silverlimetea 4 hours ago

querySelector/querySelectorAll() are great for plucking out deeply nested elements but if all you need is to find all elements of a certain class and the API gives you a tool to do exactly that, why not do that instead of reaching for the general-purpose Swiss army knife? Sure, the execution speed difference may be only measurable in microseconds, but it takes about the same amount of time to type so why not use the specific tool?

Seems quite odd to use OpenRouter as “proof” that open weights models won. If you’re using OpenRouter, you’re already looking to bypass frontier models. To suggest there’s no longer a tradeoff simply isn’t true. But this isn’t the first time I thought Mozilla was a less than trustworthy source of information.
hungryhobbit an hour ago
I think "If you’re using OpenRouter, you’re already looking to bypass frontier models." is false. Our company uses both Claude subscriptions and OpenRouter ... and a lot of what we use OpenRouter for is more Claude.
We do a little exploration with other models through it, but it's not at all accurate to say we use it because we are "already looking to bypass frontier models".
... or at least, no more than any other company that doesn't want to overpay for their tooling, but is basically happy (ATM) with the current state of Claude.

The UI is really hard on the eyes. Personally, I think the font size is way too big, and the animation timing feels off. If this is a benchmark page and not a product page, I feel like the information should be scannable at a glance. The UX is bad.

There isn't any open-source AI. There is Open AI (not to be confused with the closed company called OpenAI, which was unable to trademark its name). There's no open source AI both because the open source community doesn't have the resources to train a useful AI and because AI doesn't have source code.

GuB-42 3 hours ago
I don't know of any useful model that would match the usual definition of "open source". That is, where everything needed to build the thing is provided, such as the training data and code. Not that it would be tremendously useful anyways considering how expensive training a model is.
I much prefer the "open weights" term. It is not open source in the sense that you only get the finished product, not the actual source, but it is still open in the sense that it is not only accessible as a service.
For an analogy, take Quake for instance. When it was launched, its game server was available as an executable, so you could run it your machine, but that didn't make it open source. Only much later it was released as true open source software.

Just like how the web was won?
I think Mozilla is chasing a past formula, but the projection isn't linear enough to remain consistent, and the critical parts of the outcome, utter centralization of the market dominance of the three C's, are left out of the equation.
We might get the consolation prize, a few nerds having competitive alternatives to applaud, but we will be left with the hidden costs: stagnation by bloated market leaders, consumers and businesses pouring trillions of dollars into the commercial offerings while open development wonders where money comes from, and the leakage of these imbalances into political and social spheres.
If we follow a Mozilla template and get to the peak of Mozilla's success at the web, look at what that really is. Facebook, Amazon, Google etc are orthogonal to that equation.

Haven't been following the articles and snippets we get from these labs about training their models for a while. But I'm guessing the latest chinese models are way less based on distilling? If not, then your speed of progress is still limited by the two labs (which we are collectively, in various forms subsidizing).

This is really insane to me.
There's nothing practical about open-source models yet that makes them even remotely comparable to closed frontier models.
All the hype around GLM, Qwen, now Kimi.... Are people really this naive that they believe these reports or, more worringly, are people NOT using these models and seeing the HUGE gap that still exists?
Take a task, any medium-sized task, decently scoped that you'd trust to give to Sonnet to finish without a hitch. Now give it to ANY open-source frontier model and watch them struggle and go in circles while failing tool calls and randomly assuming things.
Open-source is and has been amazing but its so hard to deploy reliably and at scale and there's still big problems in the underlying models with instruction following and tool calling that makes it basically unusable for production workloads at a decent price point...

Claude used to be much worse than it is now, just as bad the open weights models are. And the open weights were worse. The labs will also try to keep the lead, but at some point people start seeing real value from open models. Maybe you say they're not ready yet for medium tasks, but everyone sees the writing on the wall.
brunooliv 4 hours ago
I hope you're right and I want you to be right, but, even seeing the current hype around local models, etc... and open-source models, I think the industry is currently under a big confusion where they see the benchmarks of things like Kimi, GLM, Qwen, they play with it via opencode, and they think like: "Wow this is pretty good, I want to deploy this". But they don't understand how the KV cache grows over time and can take almost as much memory as needed for a 30B param model, they dont understand that a quantized model WILL NOT be the same as a full precision one, and they surely don't see the engineering work needed to serve inference to even tens of customers at a decent quality and latency level.
The biggest moat of these giant labs and models is increasingly shifting towards deployment capabilities and (debatably) having better (proprietary) harnesses.
The models themselves can be impressive on benchmarks, but unless they can be served reliably to customers either at scale, hosted somewhere, or even on edge with predictable latency and memory usage, then frontier will always be leading.
