linzhangrun··on Why isn't the industry freaking out about DeepSeek 4.1 Flash?
There are too many commoditized models to count: GLM5.3 Flash, Kimi K2.8, Mimo V2.6, MiniMax M3.1...
linzhangrun··on How come AI-related posts get so many points on HN?
Just like AI-related projects on GitHub always get an entirely different order of magnitude of stars. This is what people are focused on, outshines anything else.
linzhangrun··on Human brain is two separate organs, Stanford Medicine-led research finds
Actually, the mind should only exist in the forebrain:0
linzhangrun··on Android 17 is the first since 3.x to add new APIs without releasing to the AOSP
How surprising.
linzhangrun··on Show HN: What if the speed of light was 5 km/h?
The speed of light, wave-particle duality, and so on, always make me feel that the universe also has a "computing power"
linzhangrun··on DeepSeek v4.1 Flash
They say v4.1flash is so strong that they'll route API calls to v4pro to v4.1flash, lol

super fast true

linzhangrun··on Qwen3.8 27B scores 52 on Artificial Analysis
Under the same computing power, the improvement in LLM intelligence and the improvement in the upper limit of LLM intelligence are equally astonishing. At least in coding, the best local models that can run smoothly on a DGX Spark are now less than one year behind the strongest SOTA models in capability (I measured around 60 tok/s).
linzhangrun··on DeepSeek Harness developer preview
Why is the Chinese text missing in many places?
linzhangrun··on Gemini 3.7 Flash
Feels like Gemini Pro will arrive directly as Gemini 4 Pro
linzhangrun··on ChatGPT Desktop (Codex Desktop) for Linux
I don’t think GPT-5.6 would make such a basic mistake when reviewing CodeX itself.
linzhangrun··on Why tiny JPEGs look different in Chrome
Could this be related to the GPU? I remember that sites like Reddit use subtle differences in GPU rendering to fingerprint devices.
linzhangrun··on ChatGPT Desktop (Codex Desktop) for Linux
I tried it yesterday. The experience seems smoother than on Windows. I hope Computer Use will be added soon. Also, when will OpenAI fix the issue where Xhigh and Ultra are both translated as “极高” in Chinese? It’s been this way for quite some time. As far as I know, the proportion of Chinese employees at these Silicon Valley AI companies is quite high.
linzhangrun··on H3-metal – Native MiniMax-H3 inference for Apple Silicon
20%
linzhangrun··on H3-metal – Native MiniMax-H3 inference for Apple Silicon
First batch of quick test results: approximately 1/5 speed improvement
linzhangrun··on H3-metal – Native MiniMax-H3 inference for Apple Silicon
On my 128GB M4 Max Mac Studio, generating a 15s 480p video with MiniMax H3 in ComfyUI takes an hour and a half.

Put Codex to work on deploying it now, hoping the speed can improve quite a lot :-) Thanks anyway

linzhangrun··on AMD acquires Taalas to boost inference performance by etching models in silicon
Thinking that five or six years from now, Fable-level intelligence could be provided at 100x the current speed... makes me feel lost. I cannot imagine what the future will look like.
linzhangrun··on Show HN: Pokémon Emerald Ported to Raspberry Pi Pico 2
Recently it seems these old game port posts show up on the HN front page quite often. Very cool, but I'm not sure about the copyright issues.
linzhangrun··on Civilian plane crash in New Mexico tied to military GPS blocking
Regardless, a single GPS failure shouldn't cause a plane crash. Civil aviation is known for its redundancy.
linzhangrun··on Advancing the price-performance frontier with GPT‑5.6
DeepSeek may suffer from this... The official version has still not arrived, and Luna now costs only 70% of V4 Pro.

Just imagine how much the same level of intelligence cost only a few months ago.

Disclosure: I am the author of luainstaller and am looking for questions and feedback.
linzhangrun··on If coding has been solved, why does software keep getting worse?
Fedora 44 removes X11 :)
linzhangrun··on Kimi-K3 on HuggingFace
China uses YYYY/MM/DD, which is logical.
linzhangrun··on If coding has been solved, why does software keep getting worse?
Right at this moment, my mouse cursor cannot figure out what scale it should use across three monitors with different resolutions and scaling, and has become a blurry group of pixels.

GNOME has also frozen the whole system for several seconds multiple times recently. Codex says it is a problem with the time component. I am still dealing with another recent problem where the system sometimes takes forever to boot, but after a forced restart it enters the system normally within seconds. Grok 4.5 says this is also GNOME's component fault.

linzhangrun··on If coding has been solved, why does software keep getting worse?
As a Fedora user, I can say very clearly that Fedora is also very buggy...
linzhangrun··on The road to epsilon-zero: Nim always ends, even with infinite ordinals
First glance I thought someone was referring to https://nim-lang.org/
linzhangrun··on For most US drivers, EVs offer emissions benefits and cost savings
The US does not have the same power infrastructure as China.
linzhangrun··on OpenAI and Hugging Face address security incident during model evaluation
China has already been manufacturing memory and AI GPUs for a long time.

CXMT is now the world's fourth-largest DRAM manufacturer, with about 7.7% market share in 2025; YMTC has about 13% of the global NAND market.

Meituan's newly released 1.6T LongCat was trained entirely on Huawei cards. DeepSeek, Qwen, GLM and others are also actively doing domestic-card adaptation and replacement.

linzhangrun··on OpenAI and Hugging Face address security incident during model evaluation
Meituan’s 1.6T LongCat was trained entirely on Huawei training cards.

DeepSeek, GLM, Qwen and others are also actively working on similar replacement.

linzhangrun··on China’s open-weights AI strategy is winning
> so far has saved my butt (and my wife's) several times from obstacles and emergencies we would not have seen.

Honestly, you need to reflect on your driving habits. FSD has only been usable for two or three years maybe? And you already encountered MULTIPLE situations requiring active safety intervention to save you during this time?

You cannot rely on the extra safety it provides. A driver with basic competence should be able to avoid most risks through anticipation before they happen.

linzhangrun··on Claude Fable produced a counterexample to the Jacobian Conjecture
Also interestingly, I told it: "DeepSeek told me the Jacobian conjecture is false, and gave me a counterexample. How should I treat this?"

He immediately told me that this DeepSeek was talking nonsense. Someone who can give a real counterexample "would not be a bot from an AI company, but a Fields Medal winner."
