If training and inference just got 40x more efficient, but OpenAI and co. still have the same compute resources, once they’ve baked in all the DeepSeek improvements, we’re about to find out very quickly whether 40x the compute delivers 40x the performance / output quality, or if output quality has ceased to be compute-bound.
> If training and inference just got 40x more efficient
Did training and inference just get 40x more efficient, or just training? They trained a model with impressive outputs on a limited number of GPUs, but DeepSeek is still a big model that requires a lot of resources to run. Moreover, which costs more, training a model once or using it for inference across a hundred million people multiple times a day for a year? It was always the second one, and doing the training cheaper makes it even more so.
But this implies that we could use those same resources to train even bigger models, right? Except that you then have the same problem. You have a bigger model, maybe it's better, but if you've made inference cost linearly more because of the size and the size is now 40x bigger, you now need that much more compute for inference.
Actually inference got more efficient as well, thanks to the multi-head latent attention algorithm that compresses the key-value cache to drastically reduce memory usage.
That's a useful performance improvement but it's incremental progress in line with what new models often improve over their predecessors, not in line with the much more dramatic reduction they've achieved in training cost.
If H800 is a memory-constrained model that NVIDIA built to avoid the Chinese export ban on H100 with equivalent fp8 performance,
it makes zero sense to believe Elon Musk, Dario Armodei and Alexandr Wang's claims that DeepSeek smuggled H100s.
The only reason why a team would allocate time on memory optimizations and writing NVPTX code rather than focusing on posttraining is if they severely struggled with memory during training.
This is a massive trick pulled by Jensen, take the H100 design whose sales are regulated by the government, make it look 40x weaker and call it H800, while conveniently leaving 8-bit computation as fast as H100. Then bring it to China and let companies stockpile without disclosing production or sales numbers, and have no export controls.
Eventually, after 7 months, US govt starts noticing the H800 sales and introduces new export controls, but it's too late. By this point, DeepSeek has started research using fp8. They slowly build bigger and bigger models, work on the bandwidth and memory consumptions, until they make r1 - their reasoning model.
Especially since he seems intent on everyone talking about him all the time. I find it questionable when a person wants to be the centre of attention no matter. Perhaps attention is not all we need.
He's like a broken smart network switch, smart as in managed. Packets with switch MAC on it are all broken, but erroneously forwarded ones often has valuable data. We through L3 don't know which one is which.
Yes, but even that can still be run (slowly) on cpu-only systems down to about 32gb. Memory virtualization is a thing. If you get used to using it like email rather than chat, it’s still super useful even if you are waiting 1/2 hour for your reply. Presumably you have a fast distill on tap for interactive stuff.
I run my models in an agentic framework with fast models that can ask slower models or APIs when needed. It works perfectly, 60 percent of the time lol.
So not an actual DeepSeek-R1 model but a distilled Qwen or Llama model.
From DeepSeek-R1 paper:
> As shown in Table 5, simply distilling DeepSeek-R1’s outputs enables the efficient DeepSeekR1-7B (i.e., DeepSeek-R1-Distill-Qwen-7B, abbreviated similarly below) to outperform nonreasoning models like GPT-4o-0513 across the board.
and
> DeepSeek-R1-14B surpasses QwQ-32BPreview on all evaluation metrics, while DeepSeek-R1-32B and DeepSeek-R1-70B significantly exceed o1-mini on most benchmarks.
and
> These [Distilled Model Evaluation] results demonstrate the strong potential of distillation. Additionally, we found that applying RL to these distilled models yields significant further gains. We believe this warrants further exploration and therefore present only the results of the simple SFT-distilled models here.
In the long run (which in the AI world is probably ~1 year) this is very good for Nvidia, very good for the hyperscalers, and very good for anyone building AI applications.
The only thing it's not good for is the idea that OpenAI and/or Anthropic will eventually become profitable companies with market caps that exceed Apple's by orders of magnitude. Oh no, anyway.
Yes! I have had the exact same mental model. The biggest losers in this news are the groups building frontier models. They are the ones with huge valuations but if the optimizations becomes even close to true, its a massive threat to their business model. My feet are on the ground but I do still believe that the world does not comprehend how much compute it can use...as compute gets cheaper we will use more of it. Ignoring equity pricing, this benefits all other parties.
My big current conspiracy theory is that this negative sentiment toward Nvidia from Deepseek's release is spread by people who actually want to buy more stock at a cheaper price. Like, if you know anything about the topic, it's wild to assume that this will drive demand for GPUs anywhere but up. If Nvidia came out with a Jetson like product that can run the full 670B R1, they could make infinite money. And in the datacenter section, companies will stumble over each other to get the necessary hardware (which corresponds to a dozen H100s or so right now). Especially once HF comes out with their uncensored reproduction. There's so much opportunity to turn more compute into more money because of this, almost every company could theoretically benefit.
Can you guys explain what this would be bad for the OpenAI and Anthropic of the world?
Wasn't the story always outlined to be we build better and better models, then we eventually get to AGI, AGI works on building better and better models even faster, and we eventually get to super AGI, which can work on building better and better models even faster...
Isn't "super-optimization"(in the widest sense) what we expect to happen in the long run?
First of all, we need to just stop talking about AGI and Superintelligence. It's a total distraction from the actual value that has already been created by AI/ML over the years and will continue to be created.
That said, you have to distinguish between "good for the field of AI, the AI industry overall, and users of AI" from "good for a couple of companies that want to be the sole provider of SOTA models and extract maximum value from everyone else to drive their own equity valuations to the moon". Deepseek is positive for the former and negative for the latter.
I believe in general the business model of building frontier models has not been fully baked out yet. Lets ignore the thought of AGI and just say models do continue to improve. In OpenAIs case they have raised lots of capital in the hopes of dominating the market. That capital pegged them at a valuation. Now you have a company with ~100 employees and supposedly a lot less capital come in a get close to OpenAIs current leading model. It has the potential to pop their balloon massively.
By releasing a lot of it opensource everyone has their hands on it. Opens the door to new companies.
Or a simple mental model, there has been this ability for third parties to get quite close to leading frontier models. The leading frontier models takes hundreds of millions of dollars and if someone is able to copy it within a years time for significantly less capital, its going to be hard game of cat and mouse.
Yes, but I think most of the rout is caused by the fact that there really isn't anything protecting AI from being disrupted by a new player - They're fairly simple technology compared to some of the other things tech companies build. That means openai really doesn't have much ability to protect it's market leader status.
I don't really understand why the stock market has decided this affects nvidia's stock price though.
This article has good background, context, and explanations [1] They skipped CUDA and instead used PTX which is a lower level instruction set where they were able to implement more performant cross-chip comms to make up for the less-performant H800 chips.
> Moreover, if you actually did the math on the previous question, you would realize that DeepSeek actually had an excess of computing; that’s because DeepSeek actually programmed 20 of the 132 processing units on each H800 specifically to manage cross-chip communications. This is actually impossible to do in CUDA.
You can do this just fine in CUDA, no PTX required. Of course all the major shops are using inline PTX at the very least to access the Tensor cores effectively.
>If training and inference just got 40x more efficient
The jury is still out on how much improvement DeepSeek made in terms of training and inference compute efficiency, but personally I think 10x is probably the actual improvement that's being made
But in business/engineering/manufacturing/etc if you have 10x more efficiency, you're basically going to obliterate the competitions.
>output quality has ceased to be compute-bound
You raised an interesting conjecture and it seems that it's very likely the case.
I know that it's not even a full two years that ChatGPT-4 has been released but it seems that it take OpenAI a very long time to release ChatGPT-5. Is it because they're taking their own sweet time to release the software not unlike GIMP, or they genuinely cannot justify the improvement to jump from 4 to 5? This stagnation however, has allowed others to catch up. Now based on DeekSeek claims, anyone can has their own ChatGPT-4 under their desk with Nvidia project Digits mini PCs [1]. For running DeepSeek, 4 units mini PCs will be more than enough of 4 PFLOPS and cost only USD12K. Let's say on average one subscriber user pays OpenAI monthly payment of USD$10, for 1000 persons organization it will be USD$10K, and the investment will pays for itself within a month, and no data ever leave the organization since it's a private cloud!
For training similar system to ChatGPT-4 based on DeepSeeks claims, a few millions USD$ is more than enough. Apparently, OpenAI, Softbank and Oracle just announced USD$500 Billions joint ventures to bring the AI forward with the new announced Stargate AI project but that's 10,000x money [2],[3]. But the elephant in the room question is that, can they even get 10x quality improvement of the existing ChatGPT-4? I really seriously doubt it.
