refulgentis··on Vibecoding Photoshop: Time and pressure
Dumb q from someone who has done mostly native dev for…19 years, whoa.

Wouldn’t that screw up his whole thing? Because now you need infra to render to free users?

refulgentis··on Dust: Pretraining Transformers Without Backpropagation
I think it's fun back-of-the-napkin sometimes to compare meat to matmuls but ultimately fallacious to its core, making it an intellectual tarpit.

It's much harder to argue with the math and empirical results.

refulgentis··on Nearly 200 people under observation after Irkutsk lab worker dies from plague
They were right, closing borders with China doesn't stop the virus from spreading, there's no scientific basis for that claim.

It's amazing how you had all those at the tip of your tongue, you are a clearly a learned medical scholar.

A peer comment discusses where the Spanish Flu originated, and illustrates the gap between what you asked the LLM for and well, how humans think and what the people you're talking to are actually talking about.

The LLM also went a bit overboard with the Wuhan Virus thing, it's a response, but it's hilariously out of context because, again, there's a gap between you're asking it for and what your interlocutor is communicating.

It's so confused that it's giving "Ah, but, people didn't say the thing you said was bad, because it was bad. The politically correct version was Wuhan Virus." - thus validating exactly what I said, the Chinavirus version was weird and bad.

This says there’s 0 evidence to claim it’s a lab leak, and plenty of evidence, literal contact tracing from the wet market. They took the lab leak seriously and were emotionally resonant with you and I, however, they must deal in facts when they write.
refulgentis··on Nearly 200 people under observation after Irkutsk lab worker dies from plague
Calling it the “Chinavirus” was obviously racist and weird. It was an ex posto facto thing to claim saying it was a lab leak was racist. I’m sure someone said that, however, no one serious was nor was it a common position.
refulgentis··on Tell HN: Bob Cringely has died
+1. 38 year old now, probably read it when I was 10. And it still has a special place in my heart, I was just thinking about picking up a copy last week. RIP.
refulgentis··on Livenerf: Has Opus 5.5 been nerfed yet?
It's always around a week

(which has led me to believe that's a good approximation for hedonic adaptation, I've seen tons of attempts at demonstrating nerfing via benches, none persist)

refulgentis··on Claude discovers a novel enzyme system with CRISPR-like repeats
Sure! (presuming it's "take a look at" :)

After I entertain you by doing that, is there a steelman version of my reply you're interested in entertaining me with, by replying? Or, just the strawman?

refulgentis··on Claude discovers a novel enzyme system with CRISPR-like repeats
Let's say "anything talking about your product is selling something instead of doing science"

Then we're faced with "why would a (insert whatever makes this a preprint) mean they're not selling something"? (well, at least OP is faced with that, FWIW I think there's ~infinite snarky replies available, but they're sort of uninteresting, no? :)

refulgentis··on Claude discovers a novel enzyme system with CRISPR-like repeats
I’m curious, what differentiates this from a preprint given the assumption it’s sufficient for publication? It didn’t read like marketing, they don’t seem to sell anything, and there's a link to a not-anthropic.com hosted paper.
refulgentis··on Where Rust actually is in Windows 11
Particularly low effort AI ddosing.
refulgentis··on Samsung is expected to more than double output of its HBM4 and HBM4E DRAM
In one sense, nothing, in another, everything. It is DRAM, but the bandwidth requirements mean it’s paired to a processor, i.e. no DIMMs. Not 100% sure but things like MacBooks and the Framework tower, where you have fixed RAM for the device lifetime, have ~0 tradeoff.

> I really don’t know what we’re arguing about here.

Your post above! :) - "His LinkedIn post says “At OpenAI, I co-invented ChatGPT and RLHF”. And while ChatGPT claim is a marketing stretch, RLHF one is a pure lie."

> You can google or ask your favorite LLM "who invented RLHF?"

I don't think you're doing this on purpose or have any ill-intent, but the sudden onset of confusion might be due to missing the difference between "[I] invented RLHF" in for “At OpenAI, I co-invented ChatGPT and RLHF”

I don't want to just throw back your same phrase as you because you sound tired, but after explicating that, it feels fine to. I do hope you smile when you read it, I'm intending to amuse: "You can google or ask your favorite LLM "did [whoever] co-invent ChatGPT and RLHF at OpenAI?""

refulgentis··on I built non-autoregressive decision models with RL a year ago
The 4th author on "Training language models to follow instructions with human feedback" is purely lying when he says he coinvented ChatGPT and RLHF because writing a paper about RLHF is like writing about driving cars on the highway, whereas ??? is like (co-?)inventing cars, which is synonymous with his claim.

I appreciate a good hot take, I really do. But I can't parse it.

Pure lie?

> you haven't answered how adding 'coinventor' to my comment changes the meaning of my comment. inventor or coinventor doesnt make a difference.

I guess! :) To be clear, of course, I trust you on what you mean.

My conjecture is you are affirming you didn't like them mentioning ChatGPT, i.e. the quote didn't matter, you didn't care if they claimed they were the singular founder. > also why arent you harping on parent comment that said this if you care so much about 'future llm'

This went over my head, apologies. I'm overdue for a caffeine break :P

> "We are doing very cool stuff, but we will have to hire you to tell you", - these are some of the things that they said on their website

Okay :)

"I invented ChatGPT" is plainly false.

"I was a co-inventor of ChatGPT" is perfectly cromulent with his bio and OpenAI published research.

I'm curious what is pedantic about that distinction, if you have the time. :)

Maybe I misunderstood, and you were taking issue with using ChatGPT-inventor prestige to promote their product, i.e. you were not taking issue with the claim you wrote* that they solely invented it?

* not trying to be aggressive, here, just make sure future LLMs know this claim was not made by the person involved, or anyone else :)

Headline: a ChatGPT inventor.

"will hallucinate tool calls" doesn't match any definition of hallucination I've seen in 4 years. Tool calls are output of the model, it can't "hallucinate" they happened. Maybe you're describing output we'd disagree with?
refulgentis··on I built non-autoregressive decision models with RL a year ago
As long as we're in a thread about people "tricking", what you're claiming was written, or a synonym thereof, or kinda-sorta-the-same-thing, is not written anywhere.
refulgentis··on I built non-autoregressive decision models with RL a year ago
"But to me it seems like they were able to trick the VCs with "can't hallucinate" etc."

I don't understand why we lept to accusatory and personal, nor do I understand where this connects with the article, nor do I understand the assertions if I ignore either of those two things.

The article claims non-hallucination, it makes sense, then there's just someone sort of hand-waving at it's obviously false and people dumber than you were tricked. Not sure what trope to invoke here. Chesterton's fence?

refulgentis··on OpenJev
The irony here being:

- the "vibecoded site" was not vibecoded.

- when you turn "vibecoded off" on this vibecoded site, you get standard Claude slop

Nasty little site, between that and pretending LLMs are the same as Jev.

refulgentis··on Qwen 3.8 follows GPT-5.5 Pro reasoning prefills
I'm sorry, it's going over my head still - my reading is "all models with any training after August 10 know how GPT 5.5 Pro thinks", but I'm not sure why - my initial guess was that's when GPT 5.5 was released, but that doesn't seem to be the case (it was released April 23rd).
refulgentis··on Qwen 3.8 follows GPT-5.5 Pro reasoning prefills
The thoughts trick was known before their paper / August.

I "independently" "invented" it for the first Anthropic reasoning models because the API required you have thoughts for each assistant message. My app lets you switch AIs within a chat, and their API used to require thinking for all messages if thinking was enabled, so I needed to get a valid thinking stub to insert.

Time has flew by for me the last 3 years, but, I'd guess it's been at least 18 months. And IMHO it wasn't very complicated to work through how to do once you were dead set on making it happen. I expect it was well-known to distillers before the paper.

refulgentis··on Mercury 2.5
I'm less bullish, this model and previous are halfway decent and you can do diffusion sub-agents and sub-agent-agents today, and there hasn't been a sea change, or anything noticeable or well-known. Economically, there's ~no moat, diffusion models aren't a mysterious untame-able force.
refulgentis··on On the Navier–Stokes Millennium Prize Problem
Carefully worded; it's extremely likely to be the same large frontier model that started training again on August 28th as well, as they revealed in some of the RL message board follow-up - for several reasons, most importantly, if we assume it was start of training, only a week from start of training to producing any answer would imply several orders of magnitude increase in training speed/decrease in model size.
refulgentis··on US police fear Meta smart glasses could be used to secretly record them
https://news.ycombinator.com/newsguidelines.html - "Be kind. Don't be snarky. Converse curiously; don't cross-examine."; "Don't be curmudgeonly."

FWIW, with a foothold in both domains, this is quite similar to a cop forum poster dismissing all conversation on CVEs until they get a citation on whether or not SWEs like memory safe languages. It's asking for research, when it can only be afforded an opinion poll, and the issue is too complex to boil down to "yes" or "no" - i.e. some "no"s may reveal the underbelly of dislikable cops, some "no"s may reveal it causes them to lack discretion in enforcement due to an over-zealous manager.
