Oh, you're writing CUDA kernels? Everyone's on Triton now. Just kidding, we're all on Mojo. We're using cuTile. We're using ROCm. We have an in-house DSL compiler targeting the NVGPU MLIR dialect but wait, Tile IR just dropped so we're going to target that instead. Our PM is on TileLang. The team lead was on CuTe but now she's back to handwriting PTX. If you're not on Pallas, you're ngmi. Our intern is building on TT-Metalium for our Wormholes. Our CFO approved an order for some big chungus wafer-scale chips so now we're porting our kernels to CSL. Our CTO is working on a kernel-less graph compiler so we won't need to write kernels anymore. Our CEO thinks we're talking about the Linux kernel. We're building Claude for dogs.

I would like to announce that I'm starting a new role at OpenAI.
I'm not but I'd like to be able to announce it.

Bend 2 is here!
It is a new programming language that blocks AI mistakes via *proof checking* - the same technique big AI labs used to solve open math problems, like Navier-Stokes.
It is also very fast, and runs on GPUs.
Watch the video. Link in the comments.
RELEASE DAY
After almost 10 years of hard work, tireless research, and a dive deep into the kernels of computer science, I finally realized a dream: running a high-level language on GPUs. And I'm giving it to the world!
Bend compiles modern programming features, including:
- Lambdas with full closure support
- Unrestricted recursion and loops
- Fast object allocations of all kinds
- Folds, ADTs, continuations and much more
To HVM2, a new runtime capable of spreading that workload across 1000's of cores, in a thread-safe, low-overhead fashion. As a result, we finally have a true high-level language that runs natively on GPUs!
Here's a quick demo:

I'm looking for my next role, in Montreal or remote! My background spans compilers, systems, and AI research.
I'd welcome introductions, leads, or a repost to help spread the word ❤️
More details about my experience and what I'm looking for: pointersgonewild.com/2026-09…

Donald Trump invented the transformer architecture. You might disagree. You might even have evidence to the contrary. But you have to ask yourself: is this really worth losing my frontier AI research lab over? Donald Trump invented the transformer architecture.

“But the pleasure of sitting by the window listening to the rain, guiding needle and thread, and letting the hours pass slowly has, in the end, been crushed beneath the roar of the machine.”
Thoughts from a DeepSeek kernel programmer on his contribution to the automation of his own craft.
astonishing blogpost from Shengyu Liu (刘胜与, also known as interestingLSY/intlsy), kernel engineer at DeepSeek. The first part is his personal struggle with the fact that his work is about to render his beloved craft obsolete. The second is…
well. let's just say we agree.

It's the year 2030 and you're downloading sketchy model weights for the new DeepSeek V10 Supersonic off Limewire.
But damn, it turns out you downloaded evil weights from a scammer. Your Discord token is now on Pastebin and the agent used your iMessage MCP to text your nan that you're in deep trouble and urgently need $2000 of Google Play cards.
i'll say it straightforwardly so no one accuses me of lying later: i can't imagine a world a year from now in which open source models aren't harshly regulated. if it turns out that they're basically not that dangerous and nobody cares, mea culpa and i'll be happy about it

Oh, it seems fine if I prompt it to keep working. I had a few times where it returned control to me too early, but it seems fine now.

Lately, I've been feeling a mundane version of this in regards to my own goals and work life.
I do a lot of things manually and when I use agents, I supervise them closely and review their outputs as it's important for me to build knowledge about the systems that I work with.
However, it's becoming obvious to me that, in the long term, it's going to be feasible to delegate entire complex software systems to agents. It's possible that humans retain some kind of X factor and, even in this future where agents do all low-level research and development, there will be some "technologist" role awaiting me. But even if that's the case, I find this idea completely uninspiring. I fell in love with compilers *because* I wanted to understand the "nuts and bolts" of how things work, to explore, to figure out how to do things differently.

I also heard through the grapevine that they’ve almost solved AI gfs.
You know, @OpenAI, I heard a rumor @AnthropicAI solved alignment and they're publishing in two weeks.

Counterpoint: compression libraries.
Zstandard, LZ4, etc are some of the highest leverage software out there and they're extremely compact in terms of LoC.
If you understand your whole codebase, the codebase isn't that important.
Real software is larger than what your brain can comprehend.

It’s insane how many organisations in this day and age rely on being able to call you during work hours from some unrecognisable number.

Lmao, imagine being a Polygon employee and reading this shit.
I'm torn internally when people take time off. Is this normal?
On the one hand, I want people to relax, enjoy time with their families and take a break. I genuinely want it.
On the other hand, it pains me so much when I know we could move faster. I don't understand how you can take time off knowing that a competitor is not.
In the end, I much prefer the latter rather than the former. I just struggle to admit it.
