pkroll··on MiniMax H3 Day-0 Support in ComfyUI: Open Weights, Native Audio, and 2K Video
People on reddit have definitely pointed out that sageattention will speed up the renders.

And it's literally the first day. Someone will make a distilled 4-8 step LoRA and we're off to the races.

Edit: did a couple of 10 second long 864/480 i2v videos on my RTX Pro 6000: sageattention bumps them up 33%, that is to say, 140.89 seconds without sageattention becomes 105.69 with sageattention on (if using the KJ Sageattention node, "allow_compile" doesn't seem to affect it, just "sage_attention" set to "auto" works fine).

EasyCache also appears to work, but does affect quality, at least with the default threshold or even down to 0.10. Still, at 0.10 threshold the same render above, with sageattention, is down to 71.33 seconds, so depending on your use case the quality hit might be worth it. Also it seems that with EasyCache the video still matches the un-EasyCached video (with the same seed), so you could use it to do seed hunting.

pkroll··on Qwen 3.6 27B is the sweet spot for local development
Since no one else posted it... I have open-webui pointed at a linux box with 128 gig of ram and an RTX Pro 6000, and after a couple of runs on trivia, had it do one of Open WebUI's conversation starters: "Show me a code snippet of a website's sticky header in CSS and JavaScript."

72.06 t/s. That's the full Qwen 3.6 27B model BF16, using MTP, running on Ollama. Yes I know I should bite the bullet and get vllm running on that box.

That was, also, at a 570 watt limit: I normally run a little less, but when I first tried this I actually forgot I had set the limit to 300 (it's a hot day, I figured why fight the A/C?), and at 300 watts the same question came back at 69.38 t/s. (The extra power matters more for compute bound things, the difference in generating LTX2.3 videos is considerably higher... but still not linear.)

pkroll··on Qwen 3.6 27B is the sweet spot for local development
Check the LLM benchmarks once it's out: it's such a common use case for these kinds of machines, you won't be waiting long.
pkroll··on GLM-5.2 is a step change for open agents
If this pans out, you're not at all kidding: https://www.youtube.com/watch?v=8ekndZwyOzo
pkroll··on Sandboxes won't save you from OpenClaw
Really? Why? I'd bet the opposite: the worst of the things happening with OpenClaw aren't being revealed.
pkroll··on The Walt Disney Company and OpenAI Partner on Sora
Not a shareholder, but on first try, it won't do it because it recognizes Iger's name. And clearly the deal is fresh because it balked at Mickey Mouse too. But it has no trouble with just, "mouse": https://sora.chatgpt.com/p/s_693ae0d25bbc819188f6758fce3f90c...
pkroll··on We ran over 600 image generations to compare AI image models
It's likely that I'm seeing this from my deep into ComfyUI bubble. My impression was that AUTOMATIC1111 and Forge and the like, were fading as ComfyUI was the "what people ended up on" no matter which AI generation framework they started with. But I don't know that there are any real stats on usage of these programs, so it's entirely possible that AUTOMATIC1111/Forge/InvokeAI are being used by more people than ComfyUI.
pkroll··on We ran over 600 image generations to compare AI image models
Did you test some local image gen software in that you installed the Python code on the github page for a local model, which is clearly a LOT for a normal user... or did you look at ComfyUI, which is how most people are running local video and image models? There are "just install this" versions, which eases the path for users (but it's still, admittedly, chaos beneath the surface).
pkroll··on What Americans die from vs. what the news reports on
Mass shootings in the US, are a little over 1 a day. School shootings are a subset, and as cudgy says, so far 13 this year.
pkroll··on Decoding Netflix's AV1 Streams
"NTSTC content at 23.976 I'd hope the player would just speed up at that point, but even if not... judder at 120 Hz is better than at 60 Hz."

I'd bet money when TVs are advertised at 120 FPS, they're really 119.88 FPS, so no judder showing 23.976 FPS and the other NTSC-off display rates.

pkroll··on Show HN: A zoomable, searchable archive of BYTE magazine
It's a regular expression, and OS/2 was referred to in many ways, so try something like: "os-2|os\/2|os2" (without the quotes)

I get 136 results, from that query.

pkroll··on Wan – Open-source alternative to VEO 3
Well, they sort of do: they keep referring to the 4090, on their Github and primary promotional pages (https://wan.video/).

But really all the various video models really want an 80+ gig vram card, to run comfortably. The contortions the ComfyUI community goes through to get things running at a reasonable speed on the current, dinky-sized vram consumer cards, are impressive.

pkroll··on Qwen3 30B-A3B
As jasonjmcghee says, they're available... but if you go to ollama.com and set models to "newest" you'll see Mistral (specifically mistral-small3.2 at this writing) because they seem to not sort the models based on newest update: only newest "group" or however you'd phrase it. So you need to scroll down to "qwen3" to see it's been updated.

Slightly frustrating. But good to know.

pkroll··on The ‘white-collar bloodbath’ is all part of the AI hype machine
https://arxiv.org/abs/2412.10849

"Our study suggests that LLMs have achieved superhuman performance on general medical diagnostic and management reasoning"

pkroll··on If it is worth keeping, save it in Markdown
I use Markdown Viewer, in Chrome: I'd bet there are multiple equivalents in Firefox and Safari. Well. I don't know what Safari's extension universe is like but it seems likely.
pkroll··on The AMD Radeon Instinct MI300A's Giant Memory Subsystem
You're not the only one thinking that: https://www.nvidia.com/en-us/project-digits/

128G of unified memory. $3K. Throw ollama and ComfyUI on that sucker and things could get interesting. The question is how much slower than a 5090, is this gonna be? The memory bandwidth isn't going to match a 512 bit bus.

pkroll··on We all took the DVD boom era for granted
That's too simple a comparison, against something that's a little more complicated. A 720p stream without adequate bandwidth can have terrible artifacts, mostly showing up during fast motion/panning/action. They can look objectively worse than DVDs.
pkroll··on FLUX.1 Tools
I don't get it: the new models still need to be used somewhere, unless you're coding everything yourself, and that means they'll mostly get used in the updated ComfyUI nodes that work with the new checkpoints and LoRAs (and are available today).
pkroll··on Teri Garr, offbeat comic actor of 'Young Frankenstein' and 'Tootsie,' has died
Well, MS isn't fatal, but it certainly doesn't HELP... people with it have a generally shorter life expectancy (by like 7 years) from complications with something else, like heart disease or cancer.

None of which takes away from it being terrible that we've lost Terri Garr.

pkroll··on ADHD headband treats symptoms in 20 minutes per day
The "fixes your colorblindness" glasses don't work, and they're still a thing.
pkroll··on Roger Corman has died
Worked with a lot of directors on their first or nearly first movies, like James Cameron, Martin Scorsese, Francis Ford Coppola, Peter Bogdonovich, Ron Howard. Even the Fantastic Four movie he produced had some pluses (the Red Letter Media review is worth watching).
pkroll··on Cold brew coffee in 3 minutes using acoustic cavitation
For anyone who hasn't gotten into the coffee insanity yet, he doesn't mean his friend literally gives the coffee acupuncture... but a cork with some acupuncture needles (or a device that looks like such) is commonly (!) used to stir/even out/redistribute/break up clumps of coffee in the portafilter before tamping. And reading that I now need to go get some coffee.
pkroll··on Cold brew coffee in 3 minutes using acoustic cavitation
Oh, THAT's pretty? I give you the Manument: https://manument.com/en/manument-leva-machine

Well. Not GIVE. It's $20K.

pkroll··on The LaserDisc
Not just dropout: the disc stacker will set each pixel to the median (if there are enough copies) or an average (if there are just two) so even slightly off pixels on one disc of three, will be caught/fixed. (You can do the same thing with VHS, but not with their stacker software. You'll need to resort to VapourSynth or Avisynth/Avisynth+.)
pkroll··on Study: Water spritz before grinding coffee yields less waste, tastier espresso
"...our very expensive grinder." To save you the effort: that's about $4300 of coffee grinder, in that video. (Weber EG-1, Black. White is $400 "cheaper.")
pkroll··on YouTube Begins Blocking Users Who Use Adblock
It's not ever illegal, as long as it's your physical copy. Is it unethical? Well if you're censoring your copy, clearly not: you still saw the ads.

But are you asking in good faith? Or are you asking because you want to get to a point where you use a service that costs money to maintain and yet you don't spend money or view ads but you still feel ethical?

pkroll··on YouTube Begins Blocking Users Who Use Adblock
No: but the ads ARE THERE. They're actually in front of you. Not so with an ad blocker.
pkroll··on YouTube Begins Blocking Users Who Use Adblock
I'm with nickthegreek: I hate ads, but YouTube saying you can't make use of our service without paying or seeing ads isn't bullying.
pkroll··on The Economics of Programming Languages [video]
We need more languages, not fewer. We need all the experimental languages, the attempts at solving issues at the language level, to get to the next Good Language. We've got plenty of Good Languages right now, but we don't get others without a LOT of little languages getting made and inspiring the next ones.
pkroll··on Tech Progress Is Slowing Down
Why is "of a radical nature" the important part here, and who gets to define it? Is fuel injection radical? Seatbelts? Crumple zones? GPS? In 1909 a car had 35HP and could peak at 53MPH, and was an ultimate death trap in an accident. Hundreds of improvements, some more radical than others, led to the cars of today being better in virtually every way, including subtle ways nobody knew mattered at the time (like not flinging people out the windshield in an accident).
