gok··on Introducing System One Models and Jev
So... a classifier model?
gok··on Xiaomi: New CPU matches Apple cores single threaded, much faster multithreaded
"Arm-designed CPU core matches Apple-designed CPU core from a year ago"
gok··on MicroGPT-C in pure C hits 10M TPS on Apple M5
It could probably go quite a bit faster using Arm SME. The entire network could fit into the ZA register.
gok··on Heart aerospace completes first flight of largest electric aircraft
New York State is funding Plattsburgh as an electric aviation R&D hub, and actually gave BETA $20M in a grant.
gok··on Starship V3
It's a fascinating design but it's been 14 years since the concept was first announced and it's never really completely worked. If it ever was possible, it's not clear the talent for it still works for SpaceX.
gok··on Interfaze: A new model architecture built for high accuracy at scale
Ok that's...just cheating. You can't take a benchmark like MMLU designed to test the performance of a single general language model and compare it to performance of a small specialized model designed to do well on MMLU.
gok··on Trevor Milton is raising funds for a new jet he claims will transform flying
An HTML5 super jet?
gok··on MacBook Pro with M5 Pro and M5 Max
consider using fp16 or bf16 for the matrix math (in SME you can use svmopa_za16_f16_m or svmopa_za16_bf16_m)
gok··on Mercury 2: Fast reasoning LLM powered by diffusion
Do you use fully bidirectional attention or is it at all causal?
gok··on 27-year-old Apple iBooks can connect to Wi-Fi and download official updates
The oldest iBook G4 is from October 2003, not even 23 years old.
gok··on U.S. jobs disappear at fastest January pace since great recession
There are many marginally employable swing voters who vote Republican when they have jobs and the Democrats in charge ask for taxes, then vote Democratic when they get put out of work and need a social safety net.
gok··on xAI joins SpaceX
> it is possible to put 500 to 1000 TW/year of AI satellites into deep space, meaningfully ascend the Kardashev scale and harness a non-trivial percentage of the Sun’s power

We currently make around 1 TW of photovoltaic cells per year, globally. The proposal here is to launch that much to space every 9 hours, complete with attached computers, continuously, from the moon.

edit: Also, this would capture a very trivial percentage of the Sun's power. A few trillionths per year.

gok··on A quarter of US-trained scientists eventually leave
Yes.
gok··on The security paradox of local LLMs
> While they provide data privacy, our research shows their weaker reasoning and alignment capabilities make them easier targets for sabotage.

If you are using any LLM's reasoning ability as a security boundary, something is deeply, deeply wrong.

gok··on We found a bug in Go's ARM64 compiler
The real lesson here should be that doing crazy shit like swizzling the program counter in a signal handler and writing your own assembler is not a good idea.
gok··on Alibaba's new AI chip: Key specifications comparable to H20
tldr it's somewhat comparable to an A100, which was released in May 2020.
gok··on AMD claims Arm ISA doesn't offer efficiency advantage over x86
This has been done in fact: https://doi.org/10.1016/j.sysarc.2024.103102
gok··on Fil's Unbelievable Garbage Collector
How hard would it be to add generational collection?
gok··on GPT-5: "How many times does the letter b appear in blueberry?"
This is like asking a human how many pixels appears in the word "blueberry".
gok··on Qwen3-4B-Thinking-2507
So this 4B dense model gets very similar performance to the 30B MoE variant with 7.5x smaller footprint.
gok··on There is no memory safety without thread safety
Java is not memory-safe in the Rust sense.
gok··on A big problem for Tesla isn't getting much attention
It's emissions credits, saved you a click.
gok··on New York’s bill banning One-Person Train Operation
CTA stopped having conductors over 30 years ago. Peak ridership and performance was in 2012, decades after the move to OPTO.
gok··on Transition to using 16 KB page sizes for Android apps and games
It's kind of too bad Linux to doesn't just support multiple base page sizes.
gok··on Why DeepSeek is cheap at scale but expensive to run locally
MoE is in general kind of a stupid optimization. It seems to require around 5x more total parameters for the same modeling power as a dense model in exchange for around 2x less memory bandwidth needs.

The primary win of MoE models seems to be that you can list an enormous parameter count in your marketing materials.

gok··on Experiments with Byte Matrix Multiplication
Curious how this compares with, say, the implementation of gemm_s8s8s32 in Intel's MKL / OneAPI.
gok··on Google must open Android for third-party stores, rules Epic judge
Which mean Tencent (Epic's parent company) will finally be free to open their app stores world-wide.
gok··on The Fastest Mutexes
Consider adopting `os_sync_wait_on_address()` on Darwin for your futex needs
gok··on Reconductoring: Boosting U.S. Grid Capacity Efficiently
previously https://news.ycombinator.com/item?id=39485940
gok··on Conservative GC can be faster than precise GC
I would have assume the major benefit to precision is that it enables compaction…
