islewis··on The AI startup drama that's damaging Y Combinator's reputation
Regardless of what you think of Pear, making the claim that they have damaged Y Combinator's reputation is pretty dramatic.

Knowing the title is in reference to Pear (and not something that could be _actually_ damaging to YC's rep) lets me know the article is probably isnt worth the time.

islewis··on OpenAI threatens to revoke o1 access for asking it about its chain of thought
The words "internal thought process" seem to flag my questions. Just asking for an explanation of thoughts doesn't.

If I ask for an explanation of "internal feelings" next to a math questions, I get this interesting snippet back inside of the "Thought for n seconds" block:

> Identifying and solving

> I’m mapping out the real roots of the quadratic polynomial 6x^2 + 5x + 1, ensuring it’s factorized into irreducible elements, while carefully navigating OpenAI's policy against revealing internal thought processes.

islewis··on Learning to Reason with LLMs
My first interpretation of this is that it's jazzed-up Chain-Of-Thought. The results look pretty promising, but i'm most interested in this:

> Therefore, after weighing multiple factors including user experience, competitive advantage, and the option to pursue the chain of thought monitoring, we have decided not to show the raw chains of thought to users.

Mentioning competitive advantage here signals to me that OpenAI believes there moat is evaporating. Past the business context, my gut reaction is this negatively impacts model usability, but i'm having a hard time putting my finger on why.

islewis··on Lottery Simulator (2023)
Can someone explain to me how the EV can be so incredibly low? I know the answer is because people will buy the tickets no matter what, but even compared to other losing games the lottery comes away looking like an absolute bandit.

A run on the simulation (n=1000000) comes back with -92% EV. It looks like -10% [1] is a rough estimate for slot machine EV, which I would ballpark into the same game genre (-EV, no skill entertainment) as the lottery.

What accounts for this payout discrepancy in what I would consider similar games? On that train of thought, what prevents a new lottery from coming in and offering a _generous_ -50% lottery, offering ~5x as much money as before?

islewis··on Project Hammer: reduce collusion in the Canadian grocery sector
Thanks for the context. I'm still not certain that an instance of collusion on the price of bread in 2015 implies wider collusion in 2024.

Ideally, the data would be proving this, but I guess my skepticism is the cost of making a claim before the research is done.

islewis··on Project Hammer: reduce collusion in the Canadian grocery sector
Big fan of any data aggregation projects like this, especially with such a relatable theme.

However it feel like the conclusion might be jumping the gun a bit. Instead of "Think there is collusion" -> finding the data top support the claim, maybe run the numbers first and see what they say? I think coming up with a strong position (Canadian stores are colluding) before looking at the data makes it enticing to find numbers that back up the claim, whether or not they are taken out of context.

islewis··on Is My Blue Your Blue?
I'm curious how the aggregate results from this test would compare to the exact same test named "Is my green your green?"

I could see the title influencing some of the more nuanced decisions in the middle.

islewis··on All text in Brooklyn
I've been either stunned, or disappointed depending on the word.

"hello" gives four images of the same building with "hello" clearly written, as well as a few images of "hello" grafiti. Impressed

"table" gives six results- four of which are clearly pictures of either leaves or the sky. Two are blurry buildings, but I cant seem to find the text "table"... it could be there though? Not impressed

"car" gives Six unique results, some of which "car" is the prefix of a word. Impressed

Either way, really cool project.

islewis··on Update on Llama adoption
"good enough" is incredibly subjective here. Maybe good enough for you, but there are many things that are not possible with either the dataset or the weights being available.
islewis··on Seven basic rules for causal inference
Could you give some examples of dependence without correlation?
islewis··on RLHF is just barely RL
Karpathy is _much_ more knowledgeable about this than I am, but I feel like this post is missing something.

Go is a game that is fundamentally too complex for humans to solve. We've known this since way back before AlphaGo. Since humans were not the perfect Go players, we didn't use them to teach a model- we wanted the model to be able to beat humans.

I dont see language being comparable. the "perfect" LLM imitates humans perfectly, presumably to the point where you can't tell the difference between LLM generated text, and human generated text. Maybe it's just as flexible as the human mind is too, and can context switch quickly, and can quickly swap between formalities, tones, and slangs. But the concept of "beating" a human doesn't really make much sense.

AlphaGo and Stockfish can push forward our understandings of their respective games, but an LLM cant push forwards our boundary of language. this is because it's fundamentally a copy-cat model. This makes RLHF make much more sense in the LLM realm than the Go realm.

islewis··on OpenAI may lose $5B this year and may run out of cash in 12 months
While I agree with your platform point, I think you still need to address OP's question of

islewis··on Netflix's bet on advanced video encoding
> Reed Hastings announced that the company was expanding into almost every country around the world — including markets with subpar broadband infrastructure and consumers who primarily accessed the internet from their mobile phone.

The optimistic take here is that the purpose of this encoding work is to make Netflix accessible consumers in ALL countries- not consumers with beefy internet.

IMO the realistic take is that Netflix knows it can do this while saving $$$ serving lower quality video to consumers who cant tell the difference.

islewis··on How The Economist’s presidential forecast works
> Nate Silver was both the best and worst thing that happened to these predictions.

Can you elaborate on this opinion further? I have a hard time aligning the rest of your post with what looks like your thesis.

Could a hardware authenticator (Yubikey) be a workaround for this? Or are there services which don't support this?

islewis··on A ChatGPT mistake cost us $10k
IMO this is the real issue.

I guarantee you that they _will_ have another production bug like this sometime in the future (every fast paced project will). You'd hope this next one wont take 5 days to identify.

islewis··on Why YC went to DC
> First, let’s prioritize open source models and more tailored AI applications to shape the competitive landscape and create real opportunities for startups

My read on this is YC believes that small companies will (are?) be locked out of the AI arms race, and are pushing for legal action to hold the door open for them.

Pushing disruptive technologies has made YC insane hoards of wealth- the fact that they feel like they need government intervention for this to continue is scary. It feels like a canary in the coal mine in regards to who is in control of AI's future.

islewis··on Sam Altman-backed nuclear startup signs major data center contract
> GPT-6 might need about 10% of the world’s computers, a large power plant’s worth of energy ... Probably this looks like a town-sized data center attached to a lot of solar panels or a nuclear reactor.

> GPT-7 might need all of the world’s computers, a gargantuan power plant beyond any that currently exist ... Probably this looks like a city-sized data center attached to a fusion plant.

islewis··on Google says no "African countries beginning with K" but Kenya has a "K sound"
> It’s disheartening to see very technically adept people still find this exciting.

I dont think this is what people find amusing. I think people are more so surprised that Google, the trillion dollar company, has pushed an update that could result in such a bad response to a somewhat basic query.

No matter how you chop up the technical details, search needs to provide good results to end users- and in this example shown, it's not doing that.

islewis··on We're ending our Samsung collaboration
> In my opinion they have harmed the cause more than anything else: instead of actual repair material (like schematics or low/high level servicing manuals)

Not sure I understand this take.

$BRAND's role is to sell devices. IFixit's role is to make repairs more accessible to the average Joe. Obviously for more tech-literate device owners this might not be needed, but everyone else it is.

The incentives for this dynamic are pretty confusing (understandably). $BRAND and IFixit need to work together for repairability to work, but companies don't really have a strong business incentive to do this outside of regulation.

Obviously nothing about this dynamic is perfect, but the claim that IFixit harms the push for more repairable devices just isn't correct.

islewis··on Framework Series A-1
I appreciate your response, thanks for the context.
islewis··on Framework Series A-1
I'm curious why they would go through the hassle of raising a relatively small amount this way instead of just asking a bit more from the VC's. Probably this?

> the RUV will sign a proxy voting agreement with Framework’s Founder and CEO, Nirav Patel that will allow him to determine how to vote the RUV's shares for most matters submitted to stockholders for approval.

islewis··on Why you should not apply to YC
It feels to me like YC's name-drop doesn't have a purpose beyond just attention/view grabbing, despite there being a few nuggets of solid reasoning sprinkled throughout the post.

> That’s 1.25%. To be fair, that’s actually quite impressive, but let’s say you have the stamina and willpower to go through YC three times in your lifetime. You’d need approximately 26 lifetimes to hit the jackpot!

This isn't the least bit unique to YC, it's just the cold reality of any high-growth startup.

If OP had framed this as "Moonshot Startup vs Lifestyle Business" it would have felt more like a good faith argument. Even "Do you have the risk tolerance to be a founder" would have worked. But basing a thread titled "Why you shouldn't apply to YC" off an illformed assumption of the readers risk tolerance is naive at best (and likely malicious given OP is selling competing services).

islewis··on Building Meta's GenAI infrastructure
I know we won't get it this from FB, but I'd be really interested to see how the relationship of compute power to engineering hours scales.

They mention custom building as much as they can. If FB magically has the option to 10x the compute power, would they need to re-engineer the whole stack? What about 100x? Is each of these re-writes just a re-write, or is it a whole order of magnitude more complex?

My technical understanding of what's under the hood of these clusters is pretty surface level- super curious if anyone with relevant experience has thoughts?

islewis··on How ChatGPT made me lazy
I don't think "lazy" is the word I would use, but I can see how some would see it like that. In my mind, GPT (and LLM's) are just the next layer of abstractions on top of a already massive stack of technical abstractions. For a SWE, this stack of abstractions crosses so many levels for a simple "hello world" to work:

1. Software (my code) 2. OS (Linux, kernels, etc) 3. Hardware (3090, 5090x, etc) 4. Electrical (Where is my energy coming from? how is it produced?)

Each of these levels could be broken into another 10 abstractions: On the software level, some people may understand how their compiler is working, but could they program in binary? What about understanding how their program interacts with memory? What about the kernel of where their software is deployed in the cloud? Do they know how their software is deployed in the cloud? Could they build the production server rack that their container is deployed on? Obviously this gets a bit ridiculous the further down you go- it's impossible to have knowledge about every part of what makes your code work.

I think that when people use terms like "lazy" or say that knowledge is being lost with abstractions like GPT, they ignore the massive list of abstractions that allow them to be productive.

I'd guess my thesis is that newer/GPT-aided engineers don't necessarily have less understanding, but their knowledge might just be shifted by one level up on the abstraction stack.

islewis··on YC: Requests for Startups
I doubt there's much thought behind it, and just the fact that each "Request" is written by a different person.
islewis··on Hi everyone yes, I left OpenAI yesterday
Given Karpathy's draw towards teaching/educational content, I've wondered where he falls on the spectrum between Sam Altman's interpretation of "Open" in OpenAI, and someone on the opposite end (like Musk).

I'd imagine if one was fully onboard with the AI/LLM commercialization train, there's no better spot than OpenAI right now.
