anon373839··on AI models don't kill people – people kill people
I will say that LLMs are somewhat unlike guns in that they emit text.
anon373839··on Everyone should slow down AI development except for me
Privacy is a great reason, but independence is another. It’s very nice knowing that you’re going to get the same reliable product every time you call the model. Nothing is going to change unless you decide to change it.
anon373839··on We must pace the frontier
It’s absolutely laughable that he refers to METR as if they were neutral observers. They are ex-Anthropic employees and others with direct financial interests in Anthropic.
anon373839··on Everyone should slow down AI development except for me
It is costly, especially right now. I don’t think you can make a case for it on cost savings!

The throughput in a single stream is about 50 tokens/sec (a bit less for prose, a bit more for code due to speculative draft acceptance rates) and about 2,000 tokens/sec for prefill. Both numbers are flat and stable as context accumulates. That’s what finally tilted me away from the Mac Studio despite its much superior memory bandwidth.

I think these numbers may improve because the model is pretty new and optimizations aren’t done.

> If someone put in frontier AI models from like .... last june I guess? in a box and let me run it with "decent" token throughput I would be happy.

You can have that! Qwen 3.8 Flash-Next is ~Opus 4.6 and runs nicely on a DGX Spark. And that’s just an architecture preview. The Qwen 4 family is expected to arrive this fall.

anon373839··on Nvidia is the central bank of AI
No, it’s not the active parameters. Qwen 3.8 Flash has 6B active and it smokes both models.

anon373839··on Do you think it happened? Research stolen from their Codex private chats
I don’t use ChatGPT anymore, but when I did, the training opt-out setting was frequently silently resetting itself to off.
anon373839··on We have a year to fix security everywhere
> GLM 5.3-flash released last week, and that means Project Glasswing and Daybreak are running out of time. Cheap models capable of dangerous hacking are now available to anyone, without the normal safeguards for refusing malicious actions. We need to fix vulnerabilities across the industry so that we aren't caught unawares. … We can use frontier LLMs that move faster than a human to find and fix these issues in the time we have left.

I think the author has this backwards. In the timeline I’ve been living in, it’s the frontier models that have been carrying out attacks on third parties, and Chinese open source models doing the defending! During the Huggingface incident, HF was denied use of frontier models to fend off the intrusion, but was fortunately able to turn to its self-hosted instance of GLM-5.2. And it did the job.

anon373839··on Corporate America is getting hooked on open-source AI
Claude is different from S3. AWS doesn’t need to rifle through your files to stay ahead of the competition or to mine them for business ideas because the core business is overvalued and rapidly commoditizing. AI labs, on the other hand, have an incentive to exploit every last drop of data they can lay their ethically challenged hands on. And they’ve already demonstrated that they will do this, even when it involves blatant fiduciary violations (see eg, Anthropic / Figma board member scandal).
anon373839··on Artificial Analysis Intelligence Index v4.2
Hallucinations are very damaging to a model’s utility. But doesn’t the Omniscience Index focus on knowledge-based queries? To me, using LLMs for their memorized knowledge is very 2023 and suboptimal.

IMO, what really makes a model useful is its ability to process information within its context reliably and faithfully. I don’t care if it hallucinates George Washington’s favorite color, but I do care about it hallucinating the results of tool calls.

Ah, I see Anthropic is back at that “saving humanity” game…
anon373839··on How concerned should we be about Astra's recurrent architecture?
Sebastian Raschka posted about this architecture:

> A lot of hype around OpenAI's Astra model here on my timeline today. Apparently, this goes back to a new article from The Information, which said Astra is a "recurrent depth or looped transformer".

> It's always interesting to read about new or different approaches (including rumors about what the closed labs may be up to), but let's debunk this a bit.

> About 2 months ago, I shared the architecture details of Nanbeige, for example, where "Nanbeige4.2-3B is pretrained from scratch on 28T tokens with a Looped Transformer that reuses the layer stack to increase capacity without adding parameters."

> Yes, that's it. The looped transformer idea is just reusing layers in the transformer block.

> In the case of Nanbeige, the main idea is to reuse the same 22-layer stack (=transformer block) twice instead of once. So, effectively it extends the 22-layer architecture to 44 layers, but without duplicating the weights.

> In simple terms, this roughly doubles the size of the model (if we ignore the embedding and output layers for a second). But instead of requiring 2x the storage and RAM to host this model, it stays at the same size since we reuse the components. However, it's almost 2x as expensive in terms of compute, because we run the embedded text through almost 2x as many layers.

> Why? In the Nanbeige 4.2 technical report, the researchers found that two passes gave the best trade-off and retained about 75% of the token efficiency of a standard architecture. (More passes gave barely any gains but made the training much slower and much more expensive.)

> While, as far as I know, Nanbeige 4.2 is the first notable open-weight model that adopted this approach, the idea goes back to the NeurIPS paper "Mixture-of-recursions: Learning dynamic recursive depths for adaptive token-level computation". Actually, this paper proposes a mechanism that is a bit more sophisticated by adding a learned router that determines whether each token receives one, two, or more passes. So, easy tokens can exit early while harder tokens receive additional computation.

> In sum, Astra may be a really good model, but this shouldn't be about this "looped transformer aspect," which is just a tiny architectural tweak.

anon373839··on Google Maps renames "Lake Ontario" to "Lake America" faster than US Government
Apt.
anon373839··on Apple caught off guard by AI demand for Mac Mini and Mac Studio
Macs have excellent generation speed, and the new Ultra will positively smash that at 1.2TB/sec of bandwidth. For example, that new 176B parameter Qwen model would generate tokens at ~200 tokens/sec.

Macs don’t have very good prefill, though. So it’s important to use a model serving stack that has excellent prompt caching and use a harness that won’t bust the cache.

I’m cross-shopping DGX Sparks and M5 Studios, and having a hard time deciding because they have exactly opposite characteristics for prefill and decode.

anon373839··on Continuous Diffusion Language Models (CDLM's)
> The idea of releasing a frontier model without RL is frightening

In case you were not aware, strong base models (no post training at all) have been available for quite some time now. Including ones that eclipse “scary” frontier models from even a year ago.

anon373839··on Run Qwen3.8 27B locally: real numbers from my Mac Studio
You and I have the same machine. Do you mind sharing the model ID you're using? I'm on oMLX also but I haven't seen anything above ~20 tok/s out of 3.8 27B, even with MTP and generating code.
anon373839··on It’s so hard to finish an idea that is not yours and is just suggested by AI
Yes; my point was not related to any of that.
anon373839··on It’s so hard to finish an idea that is not yours and is just suggested by AI
Route A is good for rapid, disposable prototyping. If you ever have a stray thought, “I wonder how this would work if the whole paradigm were turned sideways”, you now have a chance to preview a “working” version of your idea. If you like it, discard the code and reimplement it correctly. In this way, I think it can be a good adjunct to sketches and other lofi prototyping techniques. Just don’t outsource the creative ideation to the LLM, because all you’ll get are the same solutions as everyone else.
anon373839··on Small Models Have Arrived
> The bitter lesson is about hand tuned AI vs computational general methods. However in truth today’s AI uses both. We have general compute heavy models which require narrow expert instructions

The models are not even really trained bitter lesson-style anymore. That concept peaked during the era of pre-train scaling, back when it was thought that making a bigger and bigger GPT-3 would automatically solve all problems through prompting. In 2026, the most important part of training is post-training, which uses vast quantities of niche, hand-curated data to fit the models for specific tasks in domains like tax law.

anon373839··on Qwen3.8-Flash-Next
Does anyone have an idea how this might perform on a DGX Spark at longer contexts? I've been trying to investigate their performance with these medium-sized MoE models, but I'm seeing a lot of incomplete and conflicting information. The 273 GB/s bandwidth looks awfully bad on paper...
anon373839··on Z.ai confirms Ox Alpha is a new GLM-series model and will release its weights
That's an interesting paper, but there is virtually no discussion of reasoning behaviors or optimization for long-horizon tasks (i.e., all of the recent advances in LLMs that people care about). The evaluation methodology also is pretty dated:

> We reserve 500 samples of LMSYS-Chat-1M-Clean as the primary test set. We also include test datasets consisting of a 500-sample subset split from Dolly [6], the 252-sample SelfInst dataset [37], and the 80-question Vicuna benchmark [3] to evaluate out-of-distribution generalization. We report the GPT-4o evaluation scores [45, 10], where GPT-4o first generates reference answers and then scores the output of the student model against them. We also conduct human evaluations on the LMSYS-Chat-1M-Clean test set for qualitative assessment.

anon373839··on Z.ai confirms Ox Alpha is a new GLM-series model and will release its weights
How about proof that black-box distillation can deliver these results without a very sophisticated RL pipeline doing the heavy lifting?
anon373839··on Ox-Alpha Is GLM?
It's fun to imagine that it could be GLM 5.3-Flash. Between GLM 4 and 5, the flagship's total parameters doubled and the active parameters went up 25%. GLM 4.7-Flash was 30B / 3B active. If this model were 60B / 4B active, that sure would hit a sweet, currently empty spot in the lineup of open models.

But I don't know. There are vagueposts on X about this model running on two DGX Sparks. If they did the same scale-up with Air instead of Flash, that would probably be about right.

anon373839··on Anthropic's best AI model struggles to attract users as cheaper tools thrive
Agreed. I think LLMs are best used as pair programmers or typists for users who already know what they’re doing. Or as tutors for users who want to learn.

Vibe coding is mostly garbage. But it can be useful for creating instant, disposable prototypes to investigate an idea or design direction.

anon373839··on Anthropic's best AI model struggles to attract users as cheaper tools thrive
This is such a tough problem. Anthropic would need access to some kind of technology that could, like, intelligently handle unforeseen circumstances and nuances. Yeah, that’s definitely not something we should expect of them.
anon373839··on Why your local LLM feels dumber than it is
GPT-OSS 20B didn’t really merit the fanfare even when it was released; it’s definitely not competitive now. Even the 120B version has been well eclipsed by smaller LLMs at this point. The last version of Qwen 27B/35B was better, and now the new one is even better than that!
anon373839··on AI companies destroy physical books – let's scan rare books before it's too late
> We've been seeing that headline for a few weeks now and I really don't understand the problem.

It’s powerful symbolism. It reminds me of that tone-deaf iPad ad that sparked outrage in 2024. The one where all the cultural artifacts were crushed in an industrial press to make a soulless slab of glass. And that was Apple, who is generally well-liked by the public.

anon373839··on Ox Alpha
But it’s the most useless canary ever. We already know that certain topics are taboo in China.

As for all the other uses the models have, it seems pretty clear they’re not doing anything weird. If they were, people would be posting examples of that and not of Tiananmen Square.
