Are they buying them to try and slow down open source models and protect the massive amounts of money they make from OpenAI, Anthropic, Meta ect?

It quite obvious that open source models are catching up to closed source models very fast they about 3-4 months behind right now, and yeah they are trained on Nvidia chips, but as the open source models become more usable, and closer to closed source models they will eat into Nvidia profit as these companies aren't spending tens of billion dollars on chips to train and run inference. These are smaller models trained on fewer GPUs and they are performing as good as the pervious OpenAI and Anthropic models.

So obviously open source models are a direct threat to Nvidia, and they only thing open source models struggle at is scaling inference and this is where Groq and Cerberus come into the picture as they provide the fastest inference for open source models that make them even more usable than SOTA models.

Maybe I'm way off on this.


Shy of an algo breakthrough, open source isn't going to catch up with SOTA, their main trick for model improvement is distilling the SOTA models. That's why they they have perpetually been "right behind".
They don't need to catch up. They just need to be good enough and fast as fuck. Vast majority of useful tasks of LLMs has nothing to do with how smart they are.

GPT-5 models have been the most useless models out of any model released this year despite being SOTA, and it because it slow as fuck.

For coding I don’t use any of the previous gen models anymore.

Ideally I would have both fast and SOTA; if I would have to pick one I’d go with SOTA.

There a report by OpenRouter on what folks tend to pay for it; it generally is SOTA in the coding domain. Folks are still paying a premium for them today.

There is a question if there is a bar where coding models are “good enough”; for myself I always want smarter / SOTA.

FWIW coding is one of the largest usages for LLM's where SOTA quality matters.

I think the bar for when coding models are "good enough" will be a tradeoff between performance and price. I could be using Cerebras Code and saving $50 a month, but Opus 4.5 is fast enough and I value the piece-of-mind I have knowing it's quality is higher than Cerebras' open source models to spend the extra money. It might take a while for this gap to close, and what is considered "good enough" will be different for every developer, but certainly this gap cannot exist forever.

I just use a mix of Cerebras Code for lots of fast/simpler edits and refactoring and Codex or Claude Code for more complex debugging or planning and implementing new features, works pretty well. Then again, I move around so many tokens that doing everything with just one provider would need either their top of the line subscriptions or paying a lot per-token some months. And then there's the thing that a single model (even SOTA) can never solve all problems, sometimes I also need to pull out Gemini (3 is especially good) or others.
> just need to be good enough and fast as fuck

Hard disagree. There are very few scenarios where I'd pick speed (quantity) over intelligence (quality) for anything remotely to do with building systems.

If you thought a human working on something will benefit from being "agile" (building fast, shipping quickly, iterating, getting feedback, improving), why should it be any different from AI models?

Implicit in your claim are specific assumptions about how expensive/untenable it is to build systemic guardrails and human feedback, and specific cost/benefit ratio of approximate goal attainment instead of perfect goal attainment. Rest assured that there is a whole portfolio of situations where different design points make most sense.

> why should it be any different from AI models?

1. law of diminishing returns - AI is already much, much faster at many tasks than humans, especially at spitting out text, so becoming even faster doesn’t always make that much of a difference. 2. theory of constraints - throughput of a system is mostly limited by the „weakest link“ or slowest part, which might not be the LLM, but some human-in-the-loop, which might be reduced only by smarter AI, not by faster AI. 3. Intelligence is an emergent property of a system, not a property of its parts - with other words: intelligent behaviour is created through interactions. More powerful LLMs enable new levels of interaction that are just not available with less capable models. You don’t want to bring a knife, not even the quickest one in town, to a massive war of nukes.

I agree with you for many use cases, but for the use case I'm focused on (Voice AI) speed is absolutely everything. Every millisecond counts for voice, and most voice use cases don't require anything close to "deep thinking. E.g., for inbound customer support use cases, we really just want the voice agent to be fast and follow the SOP.
If you have a SOP, most of the decision logic can be encoded and strictly enforced. There is zero intelligence involved in this process, it’s just if/else. The key part is understanding the customer request and mapping it to the cases encoded in the SOP - and for that part, intelligence is absolutely required or your customers will not feel „supported“ at all, but be better off with a simple form.
Speed is great for UI iteration or any case where a human must be in the loop.
As long as the faster tech is reliable and I understand its quirks, I can work with it.
> They don't need to catch up. They just need to be good enough

The current SOTA models are impressive but still far from what I’d consider good enough to not be a constant exercise in frustration. When the SOTA models still have a long way to go, the open weights models have an even further gap distance to catch up.

GPT 5 Codex is great - the best coding model around except maybe for Opus.

I'd like more speed but prefer more quality than more speed.

This. You can distill a foundation model into open source. The Chinese will be doing this for us for a long time.

We should be glad that the foundation model companies are stuck running on treadmills. Runaway success would be bad for everyone else in the market.

Let them sweat.

I'd prefer a 30 minute response from GPT-5 over a 10 minute Response from {Claude/Google} <whatever their SOTA model is> (yes, even gemini 3)

Reason is: while these models look promising in benchmarks and seem very capable at an affordable price, I *strongly* felt that OpenAI models perform better most of the times. I had to cleanup Gemini mess or Claude mess after vibe coding too much. OpenAI models are just much more reliable with large scale tasks, organizing, chomping tasks one by one etc. That takes its time but the results are 100% worth it.

I get GPT 5.2 responses on copilot faster than for any other model, almost instantly. Are you sure they’re slow as fuck?
Confused. Is ‘fuck’ fast or slow? Or both at the same time? Is there a sort of quantum superposition of fuck?
It's an intensifier
Wasn't that supposed to be 'ass'
Then how would double intensifier look like?
well, it's not slow as fuck! it's quick as lightning and speedy as hell
Too bad, so sad for the Mister Krabs secret recipe-pilled labs. Shy of something fundamental changing, it will always be possible to make a distillation that is 98% as good as a frontier model for ~1% of the cost of training the SOTA model. Some technology just wants to be free :)
We trust in our lord and savior China and Zuck to keep the peasants fed.
> their main trick for model improvement is distilling the SOTA models

Could you elaborate? How is this done and what does this mean?

I am by no means an expert, but I think it is a process that allows training LLMs from other LLMs without needing as much compute or nearly as much data as training from scratch. I think this was the thing deepseek pioneered. Don’t quote me on any of that though.
No, distillation is far older than deepseek. Deepseek was impressive because of algorithmic improvements that allowed them to train a model of that size with vastly less compute than anyone expected, even using distillation.

I also haven’t seen any hard data on how much they do use distillation like techniques. They for sure used a bunch of synthetic generated data to get better at reasoning, something that is now commonplace.

Thanks it seems I conflated.
Yes. They bounced millions of queries off of ChatGPT to teach/form/train their DeepSeek model. This bot-like querying was the "distillation."
They definitely didn't. They demonstrated their stuff long before OAI and the models were nothing like each other.
Why would OpenAI allow someone to do that?
>Are they buying them to try and slow down open source models

The opposite, I think.

Why do you think that local models are a direct threat to Nvidia?

Why would Nvidia let a few of their large customers have more leverage by not diversifying to consumers? Openai decided to eat into Nvidia's manufacturing supply by buying DRAM; that's concretely threatening behavior from one of Nvidia's larger customers.

If Groq sells technology that allows for local models to be used better, why would that /not/ be a profit source for Nvidia to incorporate? Nvidia owes a lot of their success on the consumer market. This is a pattern in the history of computer tech development. Intel forgot this. AMD knows this. See where everyone is now.

Besides, there are going to be more Groqs in the future. Is it worth spending ~20B for each of them to continue to choke-hold the consumer market? Nvidia can afford to look further.

It'd be a lot harder to assume good faith if Openai ended up buying Groq. Maybe Nvidia knows this.

> Besides, there are going to be more Groqs in the future.

And likely some of them are going to be in countries that won't let them sell out to Nvidia.

NVIDIA release some of the best open source models around.

Almost all open source models are trained and mostly run on NVIDIA hardware.

Open source is great for NVIDIA. They want more open source, not less.

Commoditize your complement is business 101.

Then why are they spending $20 billion dollars to handicap an inference company that giving open source models a major advantage over closed source models?
Realistically groq is a great solution but has near impossible requirements for deployment. Just look at how many adapters you need to meet the memory requirements of a small llm. SRAM is fast but small.

I would guess their interconnect technology is what NVIDIA wants. You need something like 75 adapters for an 8b parameter model they had some really interesting tech to make the accelerator to accelerator communication work and scale. They were able to do that well before nvl 72 and they scale to hundreds of adapters since large models require more adapters still.

We will know in a few months.

> to handicap an inference company

That's a non-charitable interpretation of what happened. The are not "spending $20 billion to handicap Groq". They are handing Groq $20 billion to do whatever they want with it. Groq can take this money and build more chips, do more R&D, hire more people. $20 billion is truly a lot of money. It's quite hard to "handicap" someone by giving them $20 billion.

Groq doesn't have any employees. They can't do R&D because there's no one to do it. The $20B goes to Groq's investors.
From the article:

  > Groq added that it will continue as an “independent company,” led by finance chief Simon Edwards as CEO. 
The $20B does not go to Groq's investors. It goes to Groq. You can say that Groq is owned by its investors, and this is the same thing, but it's not. In order for the money to go to the investors, Groq needs to disburse a dividend, or to buy back shares. There is no indication that this will happen. And what's more, the investors don't even need this to happen. I'm sure any investor that wants to sell their shares in Groq will now find plenty of buyers at a very advantageous price.
Let's bet on this shit. Where's the Polymarket.
they spending $20 billion dollars to handicap an inference company

Inference hardware company

> handicap

Your words.

Because it's very good tech for inference?

It doesn't even do training.

And most inference providers for Open Source models use NVIDIA eg Fireworks, Basten, TogetherAI etc.

Most NVIDIA sales go to training clusters. That is changing but it'd be an interesting strategy to differentiate the training and inference lines.

You still need hardware to run open source models. It might eat into OpenAI profit but I doubt it will eat into NVIDIA's

If anything more companies in making models business the higher NVIDIA chip demand will be, till we get some proper competition at least. We badly need some open CUDA equivalent so moving off to competition isn't a problem

Nvidia's dream would be for everyone to buy a personal DGX H100 for private local inference. That's where open source could lead. Datacenters are much more efficient in their use of chips.
Exactly. Efficiency use of their chips is the enemy of Nvidia.
Yes, you are way off, because Groq doesn't make open source models. Groq makes innovative AI accelerator chips that are significantly faster than Nvidia's.
For inference, but yes. Many hundreds of tokens per second of output is the norm, in my experience. I don't recall the prompt processing figures but I think it was somewhere in the low hundreds of tokens per second (so slightly slower than inference).
> Groq makes innovative AI accelerator chips that are significantly faster than Nvidia's.

Yeah I'm disappointed by this, this is clearly to move them out of the market. Still, that leaves a vacuum for someone else to fill. I was extremely impressed by Groq last I messed about with it, the inference speed was bonkers.

If it's that good Nvidia can just keep selling it.
more like now Nvidia wants to release their own ASIC to combat google
Umm... no one tell them, okay?
Nvidia just released their Nemotron models, and in my testing, they are the best performing models on low-end consumer hardware in both terms of speed and accuracy.
I'd say that it's probably not a play against open source, but more trying to remove/change the bottlenecks in the current chip production cycle. Nvidia likely doesn't care who wins, they just want to sell their chips. They literally can't make enough to meet current demand. If they split off the inference business (and now own one of the only purchasable alternatives) they can spin up more production.

That said, it's completely anti-competitive. Nvidia could design a inference chip themselves, but instead the are locking down one of the only real independents. But... Nobody was saying Groq was making any real money. This might just be a rescue mission.

They need to vertically integrate the entire stack or they die. All of the big players are already making plans for their own chips/hardware. They see everyone else competing for the exact same vendor’s chips and need to diversify.
NVIDIA makes money no matter if the model is open weights or not. I don't think open is a concern for them and they'd very much like to be servicing China and their batch of open models I think. what's concerning them more likely is

A. The inevitable breakdown of their massive head start with CUDA and data center hardware. A serious competitor at real scale.

B. Anything that'll cool off the massive data center buildouts that are fueling them.

Seems clear that locking up a major potential competitor especially the minds behind it solves for A. And their ongoing machinations with circular funding of companies funding data centers is all about B - keeping the momentum before it fizzles.

With RAM/memory price this high, open source is not going to catch up with closed source.

The open source economy relies on the wisdom of crowds. But that implies and equal access to experimentation platforms. The democratization of PC and consumer hardware brings the previous open source era that we all love, I am afraid the tech mongols had identified the chokehold of LLM ecosystem and found ways to successfully monopolized it

They acquired in order to have an ASICs competitor to Google TPU.
> It quite obvious that open source models are catching up to closed source models very fast they about 3-4 months behind

> Maybe I'm way off on this.

If by open source, you mean downloadable from huggingface and SOTA you mean opus 4.5, yes you are way off.

I don't see where is the benefit for Nvidia to limit the open source models.

The more competition, the more shovels they sell.

It's like saying that Intel would've benefited if only Dell and few others sold servers because they brought in multiple billions per year.

More like they’re trying to snuff out potential competitors. Why work as hard to push your own products if NVIDIA gave you money to retire for the rest of your life?
Show me an affordable open source coding model thats closet to GPT-5.2-codex capabilities. Note: I do not have tons of HBM lying around
The constant threat of open source (and other competitors) is what keeps the big fish from getting complacent. It’s why they’re spending trillions on new data centers, and that benefits Nvidia. When there’s an arms-race on it’s good to be an arms dealer.
Idk- cheaper inference seems to be a huge industry secret and providing the best inference tech that only works with nvidia seems like a good plan. Makes nvidia the absolute king of compute against AWS/AMD/Intel seems like a no brainer.
How does this work considering the Nemotron models?
China may take over the open source part. That is the only country with exposure to hardware, software and political might.
Your way off, this reads more like anti capitalist political rhetoric than real reasoning.

Look at Nvidia nemotron series. They hav become a leading open source training lab themselves and they’re releasing the best training data, training tooling, and models at this point.
