I have updated OpenAI's chart[1] from yesterday to include one more datapoint: DeepSeek V4 Flash 0731. It's on the frontier.

> For the Code Agent tasks among the public benchmarks above, DeepSeek-V4-Flash-0731 is evaluated with the minimal mode of DeepSeek Harness (to be released) as the agent framework

So, are they planning to announce an optimized coding agent harness as well ? DSv4 flash is a fantastic model, and my daily driver. With reasonix or pi, I can code all day long and pay a few pennies for it. No token anxiety. Whereas the same model with fireworks/openrouter, with zdr thrown in, token costs ratchet up with no explanation. Likely that the model is subsidized for gathering usage data. I am waiting for the day I can run this locally.

If you're not paying for the model through Open router, then which provider are you buying it from? I thought that if that provider was listed on open router it would be the same price as going directly to the provider? Are you buying from a provider that isn't listed on open router already?

> Are you buying from a provider that isn't listed on open router already

I am using openrouter with zdr guardrail which routes to any provider that supposedly doesnt train on user data. I also use fireworks (directly, not via openrouter) which is a provider promising zdr and has a bunch of open weights models. My issue is that these zdr providers dont transparently disclose caching/tokens etc and so they end up being far more expensive than directly using DS.

Have you tried Novita? They're zdr and I find they usually have better cache hit rates than fireworks. No affiliation.

They announced it already, read the tech report.

"For the Code Agent tasks among the public benchmarks above, DeepSeek-V4-Flash-0731 is evaluated with the minimal mode of DeepSeek Harness (to be released) as the agent framework, using the max reasoning effort level with temperature = 1.0, top_p = 0.95."

Somewhat relatedly, how do the economics for Huggingface work? They must be hosting petabytes of models and datasets by now. I have downloaded quite a few “just in case”, only to replace them with the later iteration months later.

Does the file hosting actually cost peanuts when you do it yourself and the cloud has shattered my understanding of what it actually costs to deliver so much data?

wongarsu 5 hours ago||
File hosting is pretty cheap. Egress traffic is about $90/TB in the cloud, but around $1/TB in the real world. Storage is in the realm of $5/TB/month after adding redundancy

At the scale of Huggingface, that still amounts to a lot load of money. Significantly less than if you did the same in AWS, but still a lot

That said, they do have a deal with AWS to make the data available in AWS ip space. Maybe they got some cheap hosting out of that too

oceanplexian 3 hours ago||
It's less than $1/TB. If you have settlement-free peering it's like fractions of a penny at scale. Cloud provider DTO pricing is literally the biggest scam on Earth.

Some enterprising ISPs get into the hosting business because most of their traffic is ingress, so adding some egress revenue is effectively zero cost.

Two (linked) DGX Sparks would do it I guess. Though probably slowly (I'd guess 15-20 tok/sec for decode, but higher for prefill). So ~$8-9k USD at current RAM prices, substantially less if they ever (sigh) drop. Electricity use would actually be relatively modest.

But it makes little to no sense as long as API prices are what they are. Except for maybe privacy reasons.

the rational in one’s mind is similar to buying expensive supercar but no driving it daily.

owning a few GPUs is a lot cheaper than supercars.

I dunno. I bought the Spark in January and it has led indirectly to paid work.

I don't use it for local inference so much. I use it to learn.

I also use it as my daily driving Aarch64 development system.

Aside it's also very cool what else can be done with unified GPU memory, once you realize you have it...

For people with single RTX PRO 6000 96GB or DGX Spark 128GB, vllm-moet is a very good engine, although lesser known. It auto generate a symmetric 2-bit plane for inference and also generate a 4-bit delta cache to recover precision. Support ssd streaming oversized weight. You pick how much VRAM to allocate to each to balance out speed vs precision. 170 tps with ds-v4-flash demonstrated.

It use the stock model, no new models requires.

Worth spend a few hours to try.

The DGX Spark requires a small hack to ignore the difference between sm120 vs sm121, but it does run on sm121.

If deepseek v4 flash is beating DeepSeek V4 Pro, can we expect new V4 Pro which is on par with Opus 5 in couple weeks (even better if it beats Opus)?
jmathai 8 hours ago||
I’ve been using v4 flash for an app I’m building [1] and it’s amazing how cost effective and good it is coming from having always used gpt, opus and sonnet models.

It’s so cost effective I can offer a generous free tier since my goal isn’t to make money with it.

I get where you're coming from, and the intent to make it easier for people to find examples and verses, but there's a fine line with LLMs giving you answers, is that it's interpreting it in some form. Doesn't that run counter to prevailing ideology, that you're meant to either struggle with the materials / seek understanding yourself, or have your religious leaders interpret/receive those insights?
jmathai 7 hours ago|||
You’re correct. The hard line for me is ensuring that any scripture presented to the user is verified correct. LLMs can’t be trusted in this regard.

One feature of the app is that all scripture is verified and what’s show to the user doesn’t come from the LLM at all and instead a trusted source.

I think exploring scripture this way does not alleviate you from struggling to learn and apply it. It hasn’t for me.

weiliddat 7 hours ago||
I don't necessarily mean reguritating it, but choosing which part of the scripture to surface to the user is already some interpretation/choice. Even the devil can quote scripture (I'm playing the devil's advocate here).
jmathai 6 hours ago||
Very true. The verses selected come from a tool call. The LLM queries the app for relevant verses. It picks the keywords - so perhaps there’s bias there but the verses are handed to the LLM.

But there are ways to control and constrain the LLMs and what the user is presented with.

These are all top of mind for me and why I felt there could be a better option than asking ChatGPT directly.

I think it depends, Catholics wouldn't be able to use this because the Magisterium is the ultimate authority on interpreting Scripture, so the personal interpretation isn't really needed. This is not to say that Catholics don't read the Bible, they are encouraged to do so since it deepens their faith

On the other hand, for Protestant it varies, the High Church denominations are closer to Catholics (though none of them accept the Magisterium) in terms of scripture interpretation, but the Low Church ones (like Baptists or Non-Denominational ) are more open to personal interpenetration.

Disclaimer: I'm a Catholic, so if I made a mistake here fellow Protestants, please correct me.

hirako2000 7 hours ago||||
It doesn't prevent you from going to the source and struggle with the text, nor seek expert commentary.

What's difficult and doesn't have to be with philosophy/ spirituality is to find relevant bits off situation, theme etc.

This app does that very well, LLMs are good at entity recognition.

weiliddat 7 hours ago||
Yes it can point you to the right place, but choosing which part of scripture to point you to is already a choice/interpretation

Is the difference between this and a frontier model that the scripture is guaranteed to be real?

I'm on a team that develops a Bible study app, and we're all relatively content with how the basic models converse regarding scripture. Even as far back as GPT-4 was excellent. They occasionally have minor hallucinations (a dealbreaker for a production app), but they do an excellent job with theology and Bible scholarship, given reasonable guardrails.

I'll admit I'm coming from the perspective of "should we be implementing this?" It seems, on the surface, that a strong embedding-based verse retrieval covers the bases at a microfraction of the cost.

If you're interested, check out the development server where we're working on this. You navigate to the search (magnifying glass) and then hit "Meaning". Sorry for the confusing route; we're still deciding on back-end details and haven't focused on the front yet.

Philosophically, I don’t believe we should outsource the accuracy of scripture to any single entity (let alone a for profit secular one).

So it’s less about model choice and more about governance of scripture.

I was under the impression you were getting BOOK.CHAPTER.VERSE references from the model and then sourcing them from a ground truth db.

Anyways, impressive app! We haven't tackled such an ambitious project just for it being daunting.

irthomasthomas 4 hours ago||
It can still generate a wrong reference and select the wrong verse.
jmathai 4 hours ago||
That’s okay, IMO. Ultimately it’s the readers responsibility to apply their own intelligence. But the app should not misquote scripture itself.

Maybe I'm reading that incorrectly, but it seems to me the cost is on the X-axis.

First, your direct comparison, Deepseek V4 Flash 0731 (max effort) $0.03 (rounded up) per task @ index 50.

OpenAI Luna:

* high effort $0.03 (rounded down) @ index 46

* xhigh effort $0.04 @ index 49

* max effort $0.07 @ index 51

So I would say a fair statement would be "OpenAI Luna between 2x and 3x the price of Deepseek Flash, what you get is 2 to 5 times faster inference"

The cheapest OpenAI model that beats it is OpenAI Luna (max effort) $0.07 @ index 51 (if you take the rounding out it summarizes to triple the price for similar performance), but still close to 3x faster.

And can SOMEONE please tell artificialanalysis that using dark blue for both Deepseek AND OpenAI is an especially unfortunate choice of colors, especially today?

andai 9 hours ago|||
For anything substantial, you'd want a bigger model anyway.

For simple tasks, they're already saturated, and you'd prefer the faster model, so that you can have a realtime/interactive-ish experience.

Or to put it bluntly, it's cheaper if you don't value your time. That goes for smaller models in general -- need more handholding, more correcting -- but the Chinese ones are slower on top of that.

As for speed, Sol on Low is faster than Luna on most settings.

kamranjon 6 hours ago||
The really interesting thing about this is how big of a jump was achieved with just extra fine-tuning here. No structural changes to the model, just more data, compute and time. It makes me pretty excited for the future of small models - DS v4 flash is a relatively small model when compared to the class it's competing with, so likely similar gains can be made applying quality data/training pipeline to other smaller models.
WhitneyLand 7 hours ago||
It’s exciting that a model scoring this high is dirt cheap.

It’s also so inefficient, when they release the full performance numbers it’s not going to be good.

One example, it takes about 3.6x more tokens to finish the same work as Gemini Flash 3.6.

Bnjoroge 7 hours ago||
Using tokens to evaluate models is an outdated approach. Cost per task is what matters. Not all tokens are created equal

Yes, but… more thinking tokens also means longer solution generation time. That said, v4 Flash is a fast model. I use it all the time because it’s very smart for the price. But it is verbose sometimes.

That depends. Is it also more reliable?

If two books, one big one slim, prove the same thesis, what I would be interested in is the quality of the content, not the size. There can be a measure of efficiency in "have you really thought it through", but it is clearly complex - it requires measuring how solid the reasoning is.
