Reason for specifically citing open weight (and therefore Chinese LLMs, but not only Chinese) is that, even if they have built-in guardrails, somebody with the relevant knowledge can go in and remove them. In principle, harder to do with Anthropic or Open AI LLMs.

My best guess is that for scaled RL most of the top Chinese AI labs are starting to use a lot of Huawei for inference and Nvidia for training (maybe not for weird architectures). As agent swarms, even more scaled post-training, etc becomes the norm, this will accelerate their domestic industry. China Related

I, for one, am excited about China's progress and aspirations in designing new medicines. Pharma innovation is positive sum, and the benefits go overwhelmingly to patients and society, globally. Only a small fraction of the value is captured by producers or by the nation they hail from. A drug invented in China will cure me or someone I love just as well as one invented in the US or Europe. I do understand the fear in the US industry. And I hope that motivates us to accelerate the pace in the US, and pass some of regulatory reforms that @RuxandraTeslo and others have eloquently made the case… Quoting @fjeg1987 China wants its drugmakers to have originated 25% of first-in-class drugs and $522B in sales by 2030. This is compared to the total market of $800B today. I'm simultaneously in awe of the ambition and paranoid about the US ability to compete.

Some food for thought when designing benchmarks... So, here's a little computer-use (visual) comparison between GPT-5.6 Astra and Qwen3.8 Max.

I.e., Astra tried to approach this by drawing and layering geometric shapes. Qwen approached this pixel by pixel.

I think any LLM system that uses compaction needs to both preserve the pre-compacted text and make that text available via agent tool calls, to protect against this kind of problem.

What should be obvious is that inference, running a large language model, is the part that has to be cheap. Most of our hardware was not designed for that. LLM inference is limited by bandwidth. You do a great many matrix-vector multiplications against a huge weight matrix, and you barely reuse those weights. It is closer to streaming a video than to running a simulation or drawing a scene in a game. Graphics processors from Nvidia and others were built for something else. They pileed compute first, then bolted on high-bandwidth memory. It is expensive. An obvious answer is to invert the desi… LLMs Related

Sound like many employees at Anthropic share Jacob's POV, as many posted yesterday that (1) they agree, and (2) said that many more inside the company do also. It would be useful to name this "belief system" so that we can talk about it in a reasonable way. I suspect "doomer" seems derogatory, and "accelerationist" has others uses.

Thinking about trying Codex, I see everyone enjoying that party.

LLMs
Their words
There is no reason NOT to have every single email you get routed through an agent / LLM / API to be scored and approved or rejected And then the approved emails ordered by importance It's crazy this isn't a feature of Gmail, Fastmail etc AI could permanently fix email!

Screenshot diffing, feedback inboxes, PWAs, and of course local-first sync layer with self-hosted backend. Matches up pretty well with my approach on personal apps thus far into the LLM coding age. Curious to hear from others. Quoting @flourish.org I vibe coded three personal apps that I'd wanted for a while. They work on mobile and web, sync offline first between them, and are polished. This write up describes why, how, and what I learnt. www.flourish.org/2026/08/pers... LLMs Related

Their words
So we should also have the humility. As amazing as the LLMs are now, it could be that they eventually plateau. We haven't seen any evidence of it yet, and I think this is also why we're seeing this absolute gobsmacking levels of investment, because so far the scaling laws are true, and the more billions are poured in, the more intelligence comes out.

This thread helped me understand that the outrage about Anthropic's watermarking is the confluence of a lack of understanding of how LLMs (or any statistical language model) works and general angst at the current economics. Quoting @hern.bsky.social If you use Claude right now, then it doesn’t pick the “best” word for a sentence. It creates a distribution of possible words, assesses the probability of any given word fitting the slot, and randomly picks between them based on that probability. LLMs Anthropic Related

A korrent is a belief a person has stated in their own words: one
sentence stating the claim, backed by a quote and a source, kept at
korrents.com .
Under a name here, the quoted block is what they actually said.
The korrent beneath it is the claim those words support, in
korrents' wording — tap it to see the record, its source, and who
else holds it.
Nobody here wrote their own korrents. They are compiled from public
statements, and a person can change their mind, which is recorded too.

About the English under a post
Some people here publish in a language other than English. Where they
do, this site shows a machine translation beneath the post, in
this typeface — the site's own, not theirs.
The post itself is never changed, moved or hidden: what is set in the
serif above is exactly what the person published, and it is what to
quote them on. A translation can be wrong in ways that matter,
especially about tone.
Only the post's own words are translated. A quoted post, a linked
article and a belief on korrents.com
are left in their original language.
