>> Truly open source coming from China.

> Open weight!

They clearly were implying it's not open source.

alecco··on DeepSeek v4
X is full of "open weights!" corrections as a dog whistle by the anti-China crowd. And they are right about models from the Chinese Big Tech, but completely wrong about DeepSeek.

Did you even read my comment?

alecco··on DeepSeek-V4: Towards Highly Efficient Million-Token Context Intelligence
If 5090 has 32GB, and let's say somehow a 1-bit quantization is possible and you don't need more VRAM for anything else (forget KV cache etc), it would be able to fit a 256B 1-bit model. Just to picture it in extremes how unlikely this is.

And the active parameters come from the experts. For each token the model picks some experts to run the pass (usually 2 to 4, I haven't read V4's papers). It's not always the same experts.

OTOH, being DeepSeek, I foresee a bunch of V4 distilled FP8 models fitting in a 5090 with tiny batches and with performance close from 75 to 85% of V4. And this might be good enough for many everyday tasks.

Today is a good day for open models. Thank god for DeepSeek.

Please don't slander the most open AI company in the world. Even more open than some non-profit labs from universities. DeepSeek is famous for publishing everything. They might take a bit to publish source code but it's almost always there. And their papers are extremely pro-social to help the broader open AI community. This is why they struggle getting funded because investors hate openness. And in China they struggle against the political and hiring power of the big tech companies.

Just this week they published a serious foundational library for LLMs https://github.com/deepseek-ai/TileKernels

Others worth mentioning:

https://github.com/deepseek-ai/DeepGEMM a competitive foundational library

https://github.com/deepseek-ai/Engram

https://github.com/deepseek-ai/DeepSeek-V3

https://github.com/deepseek-ai/DeepSeek-R1

https://github.com/deepseek-ai/DeepSeek-OCR-2

They have 33 repos and counting: https://github.com/orgs/deepseek-ai/repositories?type=all

And DeepSeek often has very cool new approaches to AI copied by the rest. Many others copied their tech. And some of those have 10x or 100x the GPU training budget and that's their moat to stay competitive.

The models from Chinese Big Tech and some of the small ones are open weights only. (and allegedly benchmaxxed) (see https://xcancel.com/N8Programs/status/2044408755790508113). Not the same.

Yes, I was thinking that. But it could as well be the other way around. Using the pretrained 4.7 (1T?) to speed up ~70% Mythos (10T?) pretraining.

It's just speculative decoding but for training. If they did at this scale it's quite an achievement because training is very fragile when doing these kinds of tricks.

alecco··on Claude Opus 4.7
They don't have demand for the price it would require for inference.

They are definitely distilling it into a much smaller model and ~98% as good, like everybody does.

alecco··on Taking on CUDA with ROCm: 'One Step After Another'
Apple got it right with unified memory with wide bus. That's why Mac Minis are flying for local models. But they are 10x less powerful in AI TOPS. And you can't upgrade the memory.

I really wish AMD and Intel boards get replaced by competent people. They could do it in very short time. Both have integrated GPUs with main memory. AMD and Intel have (or at least used to have) serious know-how in data buses and interconnects, respectively. But I don't see any of that happening.

ROCm? It can't even support decent Attention. It lacks a lot of features and NVIDIA is adding more each year. Soon they will reach escape velocity and nobody will catch them for a decade. smh

> I'm afraid the music may be slowly fading at this party, and the lights will soon be turned on. We may very well look back on the last couple years as the golden era of subsidized GenAI compute.

Indeed. Anthropic is just leading the pack switching to juicy corporate users who are happy to pay thousands per month per dev and leave the fans behind. And now OpenAI is following suit. They lowered significantly the limits for the Plus $20 plan and answered concerns with vague confusing tweets about promotions.

All this is pushed by the fastest rising demand (Codex growing +50% monthly) while having a serious bottleneck building data centers and getting parts (permits, energy, memory, flash, etc).

Users on reddit and Discord are trying to switch to open models or Chinese alternatives. But there's no real replacement.

So long, Hollywood.

All these, include the war and oil spike, and all the current liquidity dramas, will be historic rounding errors.

Boomers already started to burn their $78 trillions in savings. And taxes will skyrocket for the rest to pay their fat unfunded pensions. Oh, and don't forget giving them subsidized/free healthcare. And a last FU, they collude to rise rent (they are the landlord class).

But hey, they never forget to vote.

alecco··on Private equity turned vulnerable elderly people into human ATMs
> taking care of the elderly is a fundamental tenet of Judaism

As it's done in most of Europe, Latin America, Asia, Africa. US/Canada were turned against family and tradition thanks to decades of brainwashing by movies, TV, and ads. To be cool you had to go to a college in another state. Then move to a big city. Pick career over family and having children. Take antidepressants.

This started in the 70s and is well documented.

alecco··on OpenAI offering Private Equity a return of 17.5% and early access to models
https://archive.ph/3MXXE

Exclusive: OpenAI sweetens private equity pitch amid enterprise turf war with Anthropic, sources say

NEW YORK, March 23 (Reuters) - ChatGPT maker OpenAI is offering private-equity firms a sweeter deal than rival Anthropic as both artificial intelligence companies court buyout firms to form joint ventures aimed at raising fresh capital and accelerating adoption of enterprise AI products, according to people familiar with the talks.

OpenAI is offering private-equity firms a guaranteed minimum return of 17.5%, significantly higher than typical preferred instruments, two people familiar said. It is also offering early access to its newest AI models as it seeks to enlist investors like TPG and Advent for its joint venture, three sources said.

I’m not American, and yet I can tell this is extremely unlikely to happen. I’ve lost track of all the Cassandras raising the alarm who were shot down or even laughed at. But there is still a bit more road left for the can to be kicked one more time.

How is this garbage at the front page? Unix is 56 years old, SQL is 50. Of course they are not perfect.

But the take from this post sounds ridiculous. I clicked expecting some take on consistency and some nice paradigm. But no, some weird-ass ranting with 80s UIs. I couldn't keep reading.

Iran denies Trump's claims: 'We reject all negotiations – US has failed and Hormuz will remain closed' https://www.ynetnews.com/article/0t2zpd7dr

And Brent futures are starting to climb up again fast.

Trump's post is either him freaking out of a Black Monday and/or losing military command, or it can be interpreted as market manipulation. But I don't think he is much in control anymore.

alecco··on Can the world get its supply of oil by bypassing the Strait of Hormuz?
Yes it can. It's only 20%. The difference is ME is very cheap to extract relative to other places like shale.
alecco··on Can the world get its supply of oil by bypassing the Strait of Hormuz?
At these higher prices you can safely bet other producers are drilling new wells, adding more infrastructure, and upgrading refineries.
alecco··on Can the world get its supply of oil by bypassing the Strait of Hormuz?
Eventually, yes. But 1) it's not a magic tap on/off, 2) refineries are specialized for specific types of oil, 3) a lot of ships are stuck there, 4) wells and refineries usually take a long time to restart.

Serious oil traders are saying it will take months or even more than a year to get back to normal.

The only thing containing prices at the moment is many exporters sold futures to lock-in prices for the rest of the year (it wasn't market manipulation as many suspected). But once they are sold out we'll have some interesting price discovery.
